Install Ubuntu 14.04 alongside Windows 8.1 in 10 easy steps

Posted by Gary Newell  |  at  23:27 145 comments

Introduction


By far the most read article on this site shows how to install Ubuntu alongside Windows 8 in 10 easy steps

Those instructions have helped people install Ubuntu since 12.04 but now with the introduction of Ubuntu 14.04 and many Windows users upgrading to Windows 8.1 there are a few new challenges that have been brought to the table.

Over the weekend I have played around with dual booting Ubuntu 14.04 and Windows 8.1 and the following article highlights the steps that I took to get it to work.

It may be tempting to jump in and skip the steps that show you how to back up your Windows files but I can't impress on you enough the importance of doing so.

A review of Ubuntu 14.04

Before you start it might be worth reading the latest review of Ubuntu 14.04 to make sure dual booting with Windows 8.1 is something you want to do.

1. Back up Windows

There are two steps to backing up Windows:

  1. Create a recovery drive for backing up Windows 8.1
  2. Create a file history for backing up personal files
For the recovery drive you will need a USB flash drive with at least 16gb of space. Insert the USB drive into your computer. You should make sure that you have no data that you need to keep on the drive as it will be wiped during this process. If you don't have a USB drive you can create recovery DVDs.

For the file history backup I would recommend using an external hard drive but it depends on how much data you have. If you don't have much then a USB drive will do. If you have nothing else to hand you can backup to DVDs. 

This guide assumes that you are using Windows 8.1 but most of the steps will be similar to Windows 8.

In my original guide I showed how to create recovery disks and a system image using the Windows 7 recovery tools.

In this guide I use the simpler Windows 8 recovery drive tool.

To create a recovery drive press the super key (Windows key) on your keyboard and then click on the magnifying glass in the top right corner.

Now start typing "Recovery".


An option will appear called "Create a recovery drive". Click this option. You will be asked if you are happy to give permissions for this application to run. The answer is yes you do.

A recovery drive lets you get Windows 8.1 back to a working state. 

When the "Create a recovery drive" window appears click "Next" to continue.

Click the available USB drive to be used and click "Next".

A message will appear confirming that you want to create the drive and you are warned again that all the data on the target drive will be deleted.

If you are happy that you don't need anything on your recovery drive click "Create".








It will take a few minutes for the drive to be created but eventually a screen will appear stating that the drive is ready.

Safely remove the drive, put it in a small plastic bag like a sandwich bag or in an envelope. Label the bag or envelope and place it somewhere very safe. 

If something goes wrong either whilst installing Ubuntu or later on in time you will be grateful that you followed these steps.



Now insert the drive that you want to use for storing all your personal data.

To be honest you should do this whether you plan to continue installing Ubuntu or not. 

Press the "super" key (Windows key) on your keyboard and then press the search icon in the top right corner.

Enter the words "File History". Click the option that says "Save backup copies of your files with File History".

A screen similar to the one above should appear. Click on the "Off" button to flick the switch to "On" for File History.

Click the link that says "Select a different drive". Find the drive that you want to back up to and click "Back up now".




















After a while all your files will be backed up to the new drive.

Note that this application assumes that you store all of your files under your Documents, Music, Pictures, Videos and Desktop folder. If you don't then I would recommend copying any file that that isn't stored in these folders manually using Windows Explorer.

2. Create a bootable Ubuntu USB drive

If you want to skip a step or if you have a poor internet connection then you can click here to buy a copy of Ubuntu 14.04 on a USB drive. Of course if you do that you will need to bookmark this page and wait until the USB drive arrives in the post.

If you choose to create your own bootable USB drive you will need another blank USB drive to continue. 

Insert the USB drive into your computer.

Visit http://www.ubuntu.com/download/desktop. Make sure that you choose the 64-bit version. Click "Download" to download the file.

To create a bootable USB drive the tool that I advocate using is the Universal USB Installer from www.pendrivelinux.com.

Follow the above link for pendrive Linux and scroll half way down the page until you see the "Download UUI" link. Click on the download link and wait for the program to download.

When the download has completed double click on the executable.


When the license agreement screen appears read it and then click "I Agree" if you accept the license.

Creating the drive is fairly straight forward.

The first thing to do is choose your distribution of choice, in this case Ubuntu, from the dropdown list.

Click on the "Browse" button. Find the downloaded Ubuntu ISO.


Select your chosen USB drive letter and make sure that the "We will format" option is checked.

At this point you can create the USB drive so that it persists data. This makes it possible to install software when using the live Ubuntu version and it will still be available the next time you boot from the USB drive.

Click "Create" to continue.



A summary screen will tell you what is about to happen.

Basically your USB drive is about to be completely wiped and Ubuntu is about to be installed as a live image to it.

If you are happy to continue click "Yes".






You will now see a progress bar showing how far through the process the installer is and how long it is expected to last.

Feel free to get a comfort break, have a drink or boil and egg at this point.





3. Shrink your Windows partition

Windows takes up the whole of the drive when it is first installed. In order to install Ubuntu you will need to make space for it.

Press the "super key" (Windows key) on your keyboard and click the magnifying glass in the top right corner. In the search box start typing "Partitions".

Click on the option called "Create and format partitions". This will bring up the "Disk Management" screen.













To shrink the drive, right click on the "OS (C:)" volume and select "Shrink volume".


A screen will appear showing how much you can shrink the drive by. You can of course choose to shrink the drive by less than offered but never go for any more than offered as you will break your Windows 8.1 operating system if you do.

Click "Shrink" to continue.

When you are finished you will see that there is a lot of unpartitioned space. This is where Ubuntu will be installed.

4. Turn off fast boot

To be able to boot to your Ubuntu USB drive you will need to turn off the fast boot option.

Press the "super" key (Windows key) and then click the magnifying glass in the top right corner.

Enter "Control Panel". Click on the "Control Panel" option that appears.

When the "Control Panel" appears click on the "System and Security" heading.





Now click on "Power Options".

On the following screen click on "Choose what the power button does".









A screen will appear with the heading "Define power buttons and turn on password protection".

Scroll down until you see "Shutdown Settings".

An option should be available called "Turn on fast startup" (recommended).

Uncheck this option.

Click "Save Changes".


5. Turn off secure boot

In theory you don't need to do this any more. In practise it is almost certain that you will.

Turning off secure boot depends on the make and model of your computer as each one has slightly different methods for turning it off.

Basically though click on the "super" key (Windows key) and then click on the power icon next to your user name.

Hold down the shift key on your keyboard and select restart computer. Keep the shift key held down until your computer reboots.

You will now have an option to go into your UEFI boot settings. 

Within the UEFI settings look for the option to turn off secure boot. You don't have to switch to legacy mode and you shouldn't switch to legacy mode as this will not help your cause.

Save and exit the UEFI settings

6. Install Ubuntu

When you have turned off secure boot, save and reboot. You will probably end up back in Windows.

Now at this point to boot into Ubuntu on the USB drive I had to again hold down the shift key whilst rebooting the computer. 

One of the options that appeared let me boot from the USB drive into Ubuntu 14.04 live and you should have a similar option available to you.









When you first boot into the live version of Ubuntu you will be presented with a screen similar to the one above. The only difference is that I have closed the window that shows all the keyboard shortcuts to make it easier to highlight the "Install Ubuntu 14.04 LTS" icon.

To begin the installation double click on the "Install Ubuntu 14.04 LTS" icon.

The first thing you need to do is decide which language you would like to use.

Unless you feel like the challenge isn't great enough I would choose the language that you would normally use.

Click "Next" to continue.



The next screen lets you choose which internet connection to use whilst installing Ubuntu.

I always opt for not wanting to connect and there is a good reason for that.





I live in the countryside and my internet connection is poor. I don't want the installer failing half way through because the connection dropped.

I prefer to install the operating system and run updates as a separate task later on.

If you have a good broadband connection you may wish to connect to it now so that you download updates as you go. This will slow down the initial install but will save time later on as you won't have to install lots of updates.

When you click "Next" you will be shown a tick list highlighting how prepared you are for installing Ubuntu.

As you can see I have 2 ticks because I have enough disk space and I am plugged into a power source. I chose not to connect to a network as this stage (hence the cross).

Click "Continue".

In the past there used to be an option on the "Installation Type" screen to install alongside Windows.

If you are installing alongside Windows 7 on a non-EFI based system then you will still have that option.

Click on "Something Else" and click "Next".



The next screen may look rather intimidating but it is just showing your current disk layout.

Be very careful with the next few steps. 

If you haven't taken that Windows backup, quit the installation, reboot and follow step 1 of this tutorial again.

Look at the image above. You will see a large portion of free space (710155 MB). This is where I put Ubuntu.

The free space is going to be split into 3.

The first partition is for Ubuntu and will be 50 Gigabytes in size.

The second partition is for your home partition and stores configuration files and your personal files such as music, pictures etc.

The third partition is for swap space and is used for intensive operations and suspending the computer.
When you have found the partition with free space, click on it and press the plus symbol (+) under the disk layout.

In the size box enter 50000, select logical as the partition type, select beginning of this space and choose EXT4 as the file system.

For the mount point choose / (this means root).

Click "OK".

The disk layout screen should now show a new partition for /.

Find the large section of free space again, click on it and press the plus symbol again (+).

This time you want to set the size to be the rest of the free disk space minus 2x the amount of memory in your computer.

If you have 8 gigabytes RAM, subtract 16 gigabytes.

Again choose "Logical" as the partition type, beginning of this space for where to put the partition and EXT4 as the file system.

For the mount point choose /home.

The issue of how much swap space to use is constantly up for debate. Some people say you don't need any at all, some go for 1.5 times the amount of RAM and some say 2x.

Unless disk space is at a premium I would just go for the 2x and have done with it.

In theory if you are running lots of intensive processes such as video editing then the swap space is used to store memory that isn't currently being used (swapped) to disk. This is disk intensive and slows down your computer but it will help to prevent a crash. Swap space is also used for suspending your computer.

Now find the free disk space again, click on it and press the plus symbol. (+).

Leave the size as the rest of the free disk space, choose logical as the file system and beginning of this space as the location.

Choose "swap area" as the mount point.

The final thing to concern yourself with when partitioning is where to install the boot loader.

By default it is set to /dev/SDA on the "Installation Type" screen. This can be changed but unless you are using multiple disks you should leave this well alone.

Press "Install Now" to continue.

The installation has now begun but whilst it is taking place you are asked a few configuration type questions.

First of all choose your location by clicking on the map.

Press "Continue".




The next screen asks you to choose your keyboard layout.

Simply choose the correct one for you and press "Continue".







You will now be required to create a default user.

Enter your name, a name to identify your computer, a username and a password.

You can also choose whether to log in automatically or require a password each time.


A progress bar will now show you how far through the installation you are.

You can also view a selection of messages telling you all about Ubuntu.

At this point you can take another comfort break and depending on your computer's speed you will either have time to boil an egg or wash your car.




At the end of the process you will be asked whether you want to reboot to start using Ubuntu or to continue using the live version.

When I rebooted it went straight back into Windows and I had to reboot back into the live session anyway. So at this point you can either take my word for it and stay in the live session or you can reboot and see if the installation has worked without any further steps required.

7. Boot Repair

I am going to assume that you chose to restart now and your computer booted straight into Windows without giving the option for Ubuntu.

Log into Windows and click the power icon next to your username in the top right corner.

Hold down the shift key and select to restart your computer. Keep the shift key held down until your computer reboots.

At the point of the UEFI settings appearing choose to boot from USB again.

You will now be booted back into the live session of Ubuntu.

Click on the network icon in the top right corner and choose your network connection. You will probably need to enter the security key. (If not then when you have finished with this process consider checking your router settings because your internet connection is wide open).

Now open up a terminal by pressing the "super" key (Windows key) and typing "term".

Within the terminal window enter the following commands one by one.

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo sh -c "sed -i 's/trusty/saucy/g' /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list"
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
Eventually the boot repair screen will appear.


Click on the "Recommended repair".

When I did this I received a message stating "EFI is detected". This is just an informational message as far as I am concerned because it is perfectly fine to install Ubuntu with EFI turned on.

After clicking "OK" to the EFI detected message the utility performed a few tasks and then asked me to select some text and run it in a terminal window.

If you are asked to do this open a new terminal window (press the "super" key, enter "term" into the Dash and click on the icon that appears).

Copy the text from the boot repair window by selecting it with the mouse. Press CTRL and C and then right click in the terminal window and select paste.

Make sure all the commands have run correctly. You may need to press return to get the last command to run.

Now click on the "Forward" button within the boot repair application. You may be asked to copy and paste more text.

Repeat the process of selecting all the text, press CTRL and C and then right click in the terminal window and select paste.

Make sure the commands run.

Keep following through on the process until the boot repair finishes.

If you are like me then at the very end of the process you will see a message stating that boot repair completed with errors. (not good). It is worth copying the link and posting to pastebin as suggested but I think you can just continue onto the next step.

8. Fix the boot loader

Almost there now.

Reboot your computer.

Unless you are lucky it will still boot straight into Windows and actually this is ok because we are going to use Windows to fix the boot loader.

Log into Windows and make sure you are viewing the desktop and not the tiles screen.

Hover the mouse in the bottom left corner and right click. You should see an option for the administrator's command prompt. Click on this option.

Within the administrator's command prompt type the following command:

bcdedit /set "{bootmgr}" path \EFI\ubuntu\grubx64.efi

Exit the command prompt.

9. Reboot into Ubuntu

Reboot your computer.

This time when the computer boots you should see 4 options.

1. Ubuntu
2. Ubuntu (advanced)
3. Windows (might say something similar like Windows boot options).
4. Setup

Choose option 1.

Ubuntu 14.04 should now appear. Get yourself a beer, you have earned it.

10. Reboot into Windows

Reboot your computer (click the symbol in the top right corner, click shutdown and restart).

This time when the boot menu appears click on the Windows option.

Your computer should boot back into Windows 8.

Troubleshooting

The steps I have written here are the steps I went through to get Ubuntu 14.04 to dual boot with Windows 8.1 on my Dell Inspiron.

The process will hopefully work on other computers as well and as with my last guide I will do my best to help people and clarify the points within the article.

I can't guarantee success in every case as this doesn't appear to be an exact science.

If you want to save yourself some real hassle then you might consider viewing my article "How to buy a laptop pre-installed with Linux".

You could do worse than buy a computer pre-installed with Ubuntu (make sure it will include 14.04 and not 12.04) or buy a computer without an operating system at all and install Ubuntu from scratch.

Make sure you take a backup before attempting to dual boot Windows 8.1 and Ubuntu 14.04.

    My experience with setting up UEFI multi-boot on a number of different systems has been that the UEFI firmware implementation varies significantly between different OEMs. The details of what is necessary, or what even works or doesn't, depend very much on what system you are using - and you don't even provide that information in this post. What kind of computer was it?

    Most UEFI implementations are getting to be pretty flexible and pretty stable now, and the radical procedure you suggest of replacing the Windows bootloader with Ubuntu's GRUB in the UEFI configuration is not necessary.

    - Many systems today will simply boot Linux correctly after it is installed on a UEFI firmware system, so nothing special is necessary.
    - Some systems have a UEFI Boot Priority list in the BIOS setup, and all you have to do is go there and move the Linux/GRUB item to the top of the list
    If neither of the above work, you can use the Linux efibootmgr command to set the boot priority, and put Linux first
    - If and only if all else fails, you can resort to the Boot Repair tool and bcdedit.

    The original procedure described by Ubuntu, which you quoted, was a useful workaround when it first came out. But it has become outdated and unnecessary on all but the most stubborn (broken) UEFI systems.

    1. Thanks for the comment.

      On the computer I was using which was a Dell Inspiron (sorry model number escapes me right now) the firmware system would let me select to boot windows or ubuntu but would basically always revert back to Windows.

      The efibootmgr didn't really work either.

      Hence the boot repair and bcdedit.

      I would imagine that not everyone is going to have computers with the latest UEFI and many will be stuck with stubborn systems as you put it and this guide may help them in that case.

    2. Gary, I would have preferred if you had described how to dual-boot Debian, or, even better, Fedora, with Win 8. Both of these great distributions (there or others) are backed by people who have contributed mightily to making Linux what it is. Ubuntu, on the other hand, are a band of parasitic "popularisers", eager to "make a buck" from the work of others, while contributing next-to-nothing.

    4. Suggestion: in my case i have already created previous windows partitions and i was not able to see unallocated space as free space and i can only see entire disk as a one item during ubuntu installation.

      I used 3rd party software to convert my disk from dynamic to basic from windows. Later i was able to see my other partition and my unallocated space as a free space and able to proceed the space.

  2. i have windows 8.1 and ubuntu 14.10 dual booting happily on an acer v5-572, the 1st boot is ubuntu 14.10 development.
    i found it very easy, my steps were:

    blank my whole machine immediately with gparted (free), in my opinion most laptops are sold in an almost useless state, well for me anyway.

    press F2 at boot ,change bios from eufi to legacy, change usb cdrom as primary boot, save configuration.

    boot up cdrom with gparted, change type of hard disk from dynamic to plain ordinary msdos and master boot record as grub. ( who needs more than 2TB ? as machine comes with 500mb)
    install windows 8.1 and ensure activation. update windows 8.1
    backup windows 8.1 using clonezilla( free and a wonderful program, (having used paragon, easeus and go knows how many other non-free programs )
    Now install 13.10 ubuntu remix SECURE, THIS IS BECAUSE SECURE ALLOWS YOU TO REPAIR MBR AND DELETE AN OPERATING SYSTEM.
    bootup and update ubuntu 13.10.
    update 13.10 to 14.04.
    update 14.04 to 14.10
    backup your dual boot with clonezilla
    you can now keep both operating sytems or get rid of either in 5 minutes.
    dont forget to reclaim the empty unused space if you delete either, use gparted for this, and just check the partitions with gparted.
    and all this before lunchtime.
    well allright yout warranty for the machine is probably invalid.
    this is how OAP'S spend their morning.

    1. That is an interesting way to do it. So basically you wiped your machine, turned off anything to do with UEFI and installed as you normally would.

    I don't suggest this dual boot using the same HHD. It's prone for disaster. Maybe for the more experienced - But hey aren't we all.

    BOOT REPAIR!!! That is the hell you will live.

    I have seen so many people do the dual boot and cry blood when one of the systems crashes. Or an error that is beyond their experiences. So much time can be wasted doing this.

    If you want to Linux and Windows at the same time - run a Virtual Box. Much easier and yes there are some system limitations, then get a dedicated HHD and do the right thing.

    Installer beware! this is can cause your day either to be GREAT or you will rack your head against the wall looking for help online, which I should mention, the community for the Ubuntu user beats windows any-day!

    Linux for life!

    1. Personally I would recommend separate computers than dual booting or if you want to use Ubuntu give up Windows completely. There are lots of people who like the dual boot thing and virtual machines aren't a complete win win solution as you have to use resources from the host to run the virtual machine in the first place.

    2. One of the options I think I would like to try is using my secondary SATA controller on the motherboard. My motherboard has one Intel controller and one Marvell controller. If I set the Marvell controller to RAID, and then install Ubuntu in a RAID0 configuration using its built in FakeRAID drivers (mdadm), you can be assured that Windows will never see it, because one, Windows does not have Marvell raid drivers by default and two, Windows would not understand EXT4, especially in a stripe config. It would probably, and hopefully, be completely ignored. And if it does recognize it and automatically install drivers for it, just go into the WIndows disk management and remove the drive letter, or letters for it. Then just set the motherboard bios to boot the Marvell raid array which will house the GRUB, and make the necessary changes in windows bcd and grub. Not sure if this can be done but with a Motherboard with a secondary SATA controller it sure makes me want to try, just out of sheer curiosity...

  4. ASUS must have a pretty standard implementation. I've got an N56JR-EH71 Asus laptop with Windows 8.1. I repurposed my 500+GB "data" partition that windows gave me to / 50GB, /home 100GB, and 400 GB+ of FAT32 for sharing files easily across OSs. I left secure boot on in the bios, but disabled the other options. Other than disabling secure boot, I followed the remainder of the instructions. I did not wait to try to reboot into windows. I installed boot-repair and followed all the pasting instructions, as well. I did receive an error pastebin, but the only concern that it seems to raise was a GRUB2 versioning problem.

    I rebooted a few times, testing boot into windows and into linux. It all worked like a charm. I did not have to run the windows bcdedit step. It all worked upon my first reboot after installation.

    So, your mileage may vary. I would change the instructions to run boot-repair just after installing ubuntu but before rebooting. You're already in the livedvd or usb environment, why reset it? The installer is smart enough to flush the partition tables and update the information, and boot-repair has no trouble finding the efi boot entries.

    Here's my pastebin if anyone is interested:

    http://paste.ubuntu.com/7412393/

    Definitely try to keep secure boot on. It's just a safer option against malware.

    1. There is a suggestion in my guide to just do that but I left the reboot in there because if some computers work straight away then they may not need to do the boot repair at all.

  5. It is a little easier to simply press the "Windows key + x" to get the list containing the admin cmd prompt:

  6. Gary, forget about the naysayers. You have written an excellent thorough article on how to do something that many people are hunting an answer for. And, as you stated throughout, this process may not suite every system, but this is more information on this topic than most places I've seen on the web and is a good place to start regardless of the system you're using. Great job.

  8. Hello,

    I would also like to give you a big thank you for the article! I don't understand that much of computers, but since I wasn't really happy with windows 8.1, I thought I might try ubuntu, but without touching the windows installation, in case I wouldn't like ubuntu either. And this article just showed me how to do it, and it worked without any problems!

    Just one thing: Although, as I said, I don't know that much about computers, I still like to have an idea of what I am doing. This was really well described in the beginning of the article, but in the end (when it started with the command prompts), the only option was to trust you completely and copy letter by letter what you wrote. I know that going into details would probably go beyond the scope of this matter, but I imagine that it would still be possible to give an idea of what is done, like the changing of the bootloader. I did it the way you described it, and it worked well, but after reading the comments, I am now worried if there wouldn't have been a somewhat better way (which would imply less changes, for instance) and how I could ever undo the changes I did (for whichever reason there might be).

    But still, thank you very much.

    1. Hi.

      The main advice I would give is to make sure you have followed step 1 which is to create backup and recovery media. If you do that then you always have an easy fallback.

      I can confirm that the Windows partition wasn't displayed and as long as you only use the unpartitioned space (the bit you freed up when shrinking the disk) then your windows partition will be left alone and Windows won't be messed up.

      Delete
  11. Thanks for the article. I followed every step given. But every time I restart its always going to Windows :-(

    The only deviation I took was allocated 150 MB to "Reserved BIOS boot area" in the partition section..

    Please help how to get the grub..

    There occured an error also at the end of the boot repair process. which provided an url which I need to send it to boot.repair@gmail.com. I did that too. Waiting for any reply..

    1. Hi,

      I think you need to look at step 10 again which is the bcdedit part. this switches control to the Ubuntu EFI loader from the Windows one. Make sure you have secure boot turned off.

      Delete
    2. Thanks for the reply.. Yes I have disabled the secure boot in the BIOS. Also I was able to do the bcedit part (Step 8) and it got updated successfully. When I reboot, its still going in to Windows without the grub. No clue !!
      Any idea how to bring up the grub ?
      First time when I completed the process, it didn't work. I noticed that I have created the partitions with primary instead of logical. So, I erased the partition in windows. And I did redo of everything again. But still no luck !!
      -------
      The second command to bring up the boot repair is lengthier and it is not fully visible in the post. But when I copy it got copied fully. Just thought of informing.

    3. Try using this software http://www.softpedia.com/get/System/OS-Enhancements/EasyBCD.shtml. It is a graphic interface for Windows that lets you manage your EFI partitions. Try using that to find you Linux EFI partition

    4. Thanks Gary ! Before I saw your reply, I was just exploring options in my laptop (Toshiba Satellite S50 - intel i5) , and finally it worked . :-D. .
      This is what I did :
      1: Go to - Change PC Settings - Update and Recovery - Advance Options - Restart Now - Troubleshoot - UEFI firmware Settings - Restart Now
      2: This will restart your system and it will take you to the BIOS setup.
      3: Secure boot was already disabled. So I tried to change the Boot mode under System Configuration menu - from UEFI to CEF (Legacy mode). Save and Exit.
      4: The system restarted and I got the error message that "Insert Boot device". Even Windows did not boot. (I got panicked and gave the shock of my life).
      5. But immediately I restarted again and I kept pressing F2 Key. And the BIOS setup appeared and I was happy.. Changed the Boot mode back to UEFI. Saved and restarted again.
      6. And this time.. Bingo !!! the grub menu appeared to my surprise..with the options Ubuntu and Windows Boot Manager to choose.
      7. I was able to login to both Ubuntu and Windows. :-)

      I just elaborated, so that it may help other users.. Thanks again !!

    5. Hi Gary,

      I connected the hdmi cable with youtube in Firefox. But only the wallpaper was visible on the TV. Also the right click menu, alt tab window, etc was also visible. But the side menu and the Firefox window was not visible. The cursor/pointer was visible on the tv and the touchpad was working, I was able to move the pointer.

      After I removed the HDMI cable, my cursor/pointer disappeared and my touchpad is not responding! ! I tried to restart many times, but still no luck. Its still not visible in the desktop. The pointer is visible in the login screen, but is not responding to the touchpad.

      I tried to login to my KDE session, there too the cursor/pointer is visible but is not responding to the touchpad. It is not moving.

      I then tried to connect the bootable usb linux , but in that too the cursor was invisible. So I doubt reinstalling ubuntu will help.

      Is there any fix available for this or should I remove ubuntu entirely ? :-) Kindly help if possible..

  12. Very important article to me, thank you!
    I would suggest to improve it giving more information on the porpoise of some steps like:
    - why do you need to disable secure boot?
    - what is going to do the command bcdedit?
    What I mean is to give a reason to some of the tasks.

  13. Hi Gary.

    I just started using Linux in college for C programming, so I decided to go ahead and install it on my laptop along with Windows 8.1

    I was able to get through till the part when I create a USB with the Ubuntu image, using the Universal USB, but when I boot it, I press escape to go to "Boot from USB", then I have to open the pen drive and open a folder to boot the OS from. I tried "grubX64.efi", but then I get a command prompt sort of thing, and I have no clue how to proceed after that.
    Can you please help me out at this point?

I thought that this might have been a typo and that someone else would have caught it in the comments...but alas...no.

  18. Dear Gary,
    thank you a lot for your useful tutorial: I'm from Italy, using an Inspiron 15r 5537 and unfortunately no one here (I mean italian-speaking internet) knows properly how to turn it into a dual boot kickassing machine...
    But I'm sorry to observe that even this guide doesn't work with my lap ;(
    In detalis (and without taking notice of the AMD Radeon issues with Ubuntu live...):

    1) I've followed steps 1-7 without problems, but I noticed a difference in my boot-repair process: before "the very end of the process" (that, yes, also to me shows "a message stating that boot repair completed with errors"), it opens a window in which is written "WinEFI detected. Do you want to activate [Backup and rename Windows EFI files]?" with a No/Yes choice. After reading this: http://ubuntuforums.org/showthread.php?t=2195025&p=12880914#post12880914 , I chose Yes.
    2) I've followed step 8 without problems, but after the reboot no grub appears: Windows restarts placidly as if I've done nothing.
    I've also tried the solution suggested here by Subin Raju (17 May 2014 01:26), but I'm not lucky the same: grub still lies under the overwhelming Win 8.1.

    Any other idea on how to recover my grub?
    Thank you in advance,
    diego

    1. Try using one of the graphical tools for EFI such as http://www.easyuefi.com/index-us.html. It lets you choose which EFI boot partition to load first.

    2. Fixed, but I dunno how:
      I've used easyuefi as you suggest, but it can't find the Ubuntu partition.
      So I tried to restart from step 7 in order to click "no" to that window and see... but there is no window this time, and magically grub reappears (without typing the command line in Windows as in step 8). Who the hell knows!
      BTW I've temporary fixed the AMD Radeon issue by installing Gnome and setting GDM as the display manager.

      Thank you at last, you saved me.

  19. Many thanks for this! I guess that I am lucky with my particular laptop, a Lenovo Z710. I did not disable the Secure Boot as in step 5, from a USB stick installed Ubuntu 14.04 in the space freed up in Windows 8.1, and once it had completed the installation, allowed it to reboot. And there it was: Ubuntu / Grub with the option to load the Windows boot loader. Dual boots between the two without any further work. And the One Key recovery (something specific to Lenovo, also used to access the BIOS and boot options) still works without issue too. Brilliant!

  20. Thank You! I was following the instructions step by step, and at step 7 you assumed that people would reboot. I wish I would have because when I did reboot to get to Windows and follow the rest of the instrucctions, I noticed my dual-boot was working already. Everything works fine. Toshiba Satellite C55t. Even the touch screen works with Ubuntu. Thanks again as I would have completely screwed it up without your guide.

Now i have both Windows and Ubuntu installed, but in order to use Ubuntu, I need to press escape when I turn the computer on, and then choose boot options, then select Ubuntu, and only then do I see the four options you describe above. Do you have any tips about how I could make the computer go straight to the options screen when I switch it on?

  23. Dear Gary..

    Thanks for the article. Luckily on the new Hp Pavilion machine, I can easily install Ubuntu 14.04 alongside pre installed windows 8.1 without any disabling of secure boot or uefi. I decided to follow the advice here (http://askubuntu.com/questions/221835/installing-ubuntu-on-a-pre-installed-windows-8-64-bit-system-uefi-supported) and attempted to just go ahead with the install with both secure boot and uefi enabled. But your post provided some very important info on creating partitions etc. Plus it gave a very clear understanding of the mechanics of why things are they way they are with dual boot these days, and what to do if something goes wrong. Thanks for putting in the time to get this together.

  24. I have been using Ubuntu/Linux for about 8 years now as a duel boot on any computer I care about/need. I have to say. I was at a crossroad with my new Toshiba laptop. And ready to call it quits. until I found this! Now I can go through the necessary growing pains of familiarizing myself with Windows 8 while also enjoying Ubuntu 14.04.

    Thank you

  25. Thank you for writing this blog entry. I followed your procedure as carefully as I could, but it ended in disaster. I write this detailed reply to warn others of what might happen, to describe what ultimately worked for me, and to provide some well-intentioned suggestions for how your blog entry can be improved. If everyone has as much trouble as I did installing Ubuntu alongside Windows 8, it certainly won't bode well for Ubuntu.

    First of all, let me describe my setup. I have an HP 400-224 PC with 1 TB disk space and 6 GB RAM, running Windows 8.1. I also have an external 1 TB disk. My original plan was to use the external drive as a backup for Windows, and as the Ubuntu system disk. That way, I thought, I could boot Ubuntu from any of my PCs. However, after reading your stern warning to leave the device for the boot loader to be sda, I decided it would be better to partition the internal drive and install Ubuntu there.

    I dutifully followed your advice to create a set of System Repair DVDs, I also went a step further by creating a system image on my external drive, so that I wouldn't have to reload all the Windows updates and other software I needed. I had obtained a Ubuntu 14.04 LTS Desktop 64-bit DVD from OSDisc.com, and used it instead of the bootable USB drive obtained from Step 2. After installing Ubuntu, I rebooted, and Windows 8 came up. I then ran Boot Repair exactly as you described, and later bcdedit. Your procedure calls for setting {bootmgr} to \EFI\ubuntu\grubx64.efi, but I saw no evidence that this file existed. Everything else in your procedure seemed to work perfectly, so I relied on blind faith and made the change.

    When I restarted, I got the message, “No boot device found. Please insert a boot disk and restart.” At this point I had no idea what to do, other than perform a complete reinstall of Windows 8 from my System Repair disks. Furthermore, the system image I created wouldn't reload because the size of the image no longer matched the size of my recreated hard drive. So I had to go through the painful procedure of installing all the Windows 8 updates, printer drivers and other necessary software (Office, Java, Flash, Acrobat Reader, etc., etc.)

    Now here's what worked for me. I left the internal hard drive alone and shrank the size of the external drive partition. I didn't change anything regarding the boot order, secure boot or fast boot. I ignored your admonition and set the Ubuntu boot device to be sdb. I installed Ubuntu 14.04 LTS on the external drive and rebooted. Grub64 came up and allowed me to select which OS to boot. When I defaulted, Ubuntu came up. If I select Windows, then that comes up. When I disconnect the external drive, only Windows comes up. Everything works perfectly.

    Finally, here are a few suggestions to improve your blog entry:
    1. Insert a recommendation to invest in a second hard drive (either internal or external) for Ubuntu. It will make life a lot easier.
    2. Say it's OK to change the boot device to a second drive, if you have one.
    3. Please comment on what the “Type of partition” (primary or logical) means, and why you would want to choose one over the other.
    4. In step 7, please elaborate on what you mean by “choose to boot from the USB again.” I think this is where I went wrong. When I booted from my Ubuntu Desktop DVD, I got two choices: “Try Ubuntu” and “Install Ubuntu.” Since I had already installed Ubuntu, I chose “Try Ubuntu.” Then when I thought I was running Disk Repair on my Ubuntu installation, I was actually running it in a sandbox created for the purpose of “Trying Ubuntu.”
    5. Provide ways that a user can verify that the new bootmgr (grub64.efi) actually exists, before committing to using it.
    6. Describe a way for someone to return {bootmgr} to its original state, short of reinstalling the entire system from scratch.

    1. Yes you can. In the past they would have given you a physical DVD to boot from and if you wanted to you could restore from DVD as many times as you wanted. Now the onus is on you to create that physical DVD/external drive etc.

  28. Hi, Gary. I've had a lot of trouble with this. I'm using an HP Envy touch with Windows 8.1 installed, and I followed your instructions to the letter. The only problem is when you say

    "When I rebooted it went straight back into Windows and I had to reboot back into the live session anyway. So at this point you can either take my word for it and stay in the live session or you can reboot and see if the installation has worked without any further steps required."

    When I reached that point, it simply opened up the screen saying "Try Linux before installing it" yada yada yada. Then, I went through the whole boot repair thing, as you said. I still don't get a screen allowing me to choose what OS I want to start. Also, every time I plug in the thumb drive I the whole thing starts again. I feel like I'm walking in circles. Could you please help?

However, she probably never uses it or very very rarely in any case. But always keep it in a corner.

I know this would be a senseless act of aggression, though; as probably even he uses a Mac since this stink-bomb of an OS was released. I've used Ubuntu since 8.04, and have dual booted every single computer I've ever owned from Windows 98 up to Windows 7. I have NEVER had a problem. Not even with Vista, and I thought I'd go spare with that OS! Boy, if only I had done the research before hand, I'd have built a new laptop. I'd have a better machine, and a dual boot XP/Ubuntu.

    Puke to you Windows 8! I hate your stinking guts.

  45. Gary, thank you for providing these instructions. They are the most useful I have found for setting up a dual boot system with Windows 8.1. I am dual booting Windows 8.1 with Ubuntu 14.04 on a Dell Inspiron 15R. I can follow all of your instructions until I go to edit the BCD so I can have the Windows Boot option in the Grub2 menu. When I run the bcdedit command in the Command Prompt (Admin), I get the following message:

    "The boot configuration data store could not be opened. The system cannot find the file specified."


    I cloned my computer fresh out of the box before I began, and the first time I set up the dual boot, Windows was in the grub, and then disappeared when I edited the grub trying to make Windows the grub default. Then, when I tried to get Windows back in using sudo update-grub, the grub menu started to come up as a blank, black window before booting into Ubuntu. Since I had no luck restoring the grub at all, I scrapped everything and started over by using the image to restore the computer back to factory defaults. Since then, anytime I install Ubuntu and run the boot-repair, the Windows boot is missing from the grub.

    If you can provide me any insight how to get around this and get Windows in the grub, I would appreciate it.

    Thank you.

  48. Hey Gary, I'm trying to get Linux because I need to program in Ruby using Rails and was told the command line is the best on Linux.
    I'm terrified I'm going to mess up my new self-built PC though.
    I'm trying to back up the OS as suggested and bought a 32GB stick just for this... Yet, when I do the create recovery, there is no recovery partition on my drive to copy leaving only a 256MB requirement.
    Did I do something wrong when first installing my 8.1 onto my computer? Or can this recovery partition still be made?

    Also, I have a macbook that I never use anymore, would you recommend installing Linux onto it instead of my PC? I'm not sure if it's a more difficult process or if it'd work okay or anything. I feel terribly unknowledgable on the subject and my research just leaves me confused.

    1. Hi Jesse,

      When you create the recovery drive using the Windows 8 tool it should give you an option for which drive to create the recovery drive on. (I.E your USB drive).

      Select that drive and continue. Test it out. Reboot the computer with the recovery drive in to see if it loads. (Obviously don't actually recover though).

      You should also do the file history backup as suggested in the guide to backup important files.

  52. Hello,

    While doing step 5 "Turn off the secure boot", my OS got corrupted with a message of missing or deletion of boot code.

    So I used automatic repair by inserting the OS DVD and booting it.

    After repair, the OS got started normally and my data of all primary partitions got recovered.

    But data of logical drive didn't recover & in disk management, it shows the free space instead of my logical drive. Also another primary partition of around 7GB created with the name of PBR Image.

    Now how to get back the data of logical drive???

    1. Did you follow the first step and create a system recovery drive. If you did then run the recovery tools and recover the system using the recovery drive.

  53. @Gary Newell,

    Hello, I am going to try out this guide today. I have spent the last 4 days trying to get both 14.04 LTS and my Windows 8.1 dual boot setup working. Both must be installed on my Intel FakeRAID BIOS setup. I do not know exactly why but Boot-Repair is not working properly after installing Windows, and I tried EASYBCD from within windows but it completely destroyed a fresh Windows install. So, right now I have a fresh install of Ubuntu 14.04 already working brilliantly in FakeRAID. I have an unallocated space of 190gb for Windows that I need to get it installed onto soon. I tried using gparted from within the live session but Windows 8.1 refuses to use it unless I let windows create the partition itself. So, right now I have Ubuntu installed and I do NOT have Windows installed.

    Can you suggest where in your guide I should start from, and if it will work with fakeraid using dmraid? Thank you

    1. OK, this is cool, I just found a new tool called "Dual-boot Repair Tool for Windows 8.1" so maybe I can just install Windows now and run this automated tool and hope it fixes the dual boot problem.

    2. Not sure about this one. I usually install Windows first and then Ubuntu because of Windows obsession of being the only OS there is.

  54. Hello. I'm having some problems.
    I got a Inspiron 15R SE (or 7520). It got some intel technology and a 32gb SSD card along with the 1TB hard drive.
    I did all steps you said. However, when I come to the "installation type" on ubuntu, nothing appears in the box. it is completely blank! you have any idea why that happens?
    could be a problem recognizing the ssd or the intel stuff?

    thanks,

  55. Is it possible to follow same steps of partitions and install a third operating system along with ubuntu and win8?

    ReplyDelete
    Replies
    1. It should be marginally easier. You already have the system booting from GRUB. You might get away with booting the third operating system (for instance Kubuntu) and then using the install alongside option. Not something I have tried but that is what I would expect to happen. Again take good backups first. It might be worth setting the partitions up yourself to make sure you are installing to the right place and not overwriting Windows

    While configuring the partitions in installation of ubuntu, it didn't show any of the partitions I have made in 8.1, neither primary or logical drive nor unallocated space of 50GB (made for ubutu).

    How to make windows partitions visible in Ubuntu installation & will 50GB space be sufficient for proper functioning of ubuntu?

  57. Hi Gary, I followed your instructions but when I got to the last stage where I used the usb installer to upload the iso file from my usb, it tells me two things: first, download is complete and then a message follows which says could not retrieve the iso file from archive. It is confusing because I am getting these two messages same time and it takes about 10 seconds for these two to show up....I'm I doing anything wrong? Also on the UEFI, I turned off only the secured boot but did not disable the fast boot. Another instance, I disabled both but still not working...Last, prior to this, I had attempted previous installations with linux and unetbooting and it seems their boot loaders persist on the windows even though I deleted/uninstalled them from "programs"...could these boot loaders be the reason? I am trying to take them off but it seems I am lost from some of the help I got on creating a recovery cd to restore the original settings in order to get rid of the boot loaders of the previous downloads....please let me know what you think about this...thanks a lot...

  59. Hello, you're great! The article really helped me go through all the steps and install Ubuntu 14.04 alongside windows 8.1.
    BUT, when I boot Ubuntu, it shows a message:
    "The system is running in low-graphics mode. Your screen graphics card and input device settings could not be detected correctly. You will need to configure these yourself".

    I searched about this error and I followed the instructions but none of these work because I get errors such as "could not resolve 'security.ubuntu.com' or failed to fetch http://....
    (probably I am not connected on the internet?)
    I have to note that this is the first time I install Linux. Before that,I had only windows 8.1.
    Thanks in advance :)

  64. Have a new homestead computer (Asus Z87) with Windows 8.1 that I installed in UEFI mode on a 4TB hard drive.

    Tried to boot from a USB drive (14.4) and later also from a dvd (14.4) and it boots ok and I can glimpse Ubuntu but the screen looks very strange.

    Tried to boot from an old DVD (Ubuntu 13.?) And then the screen looks good but do not dare to install when the DVD is not booting in UEFI.

    Any ideas how I can do?

    4. Maybe the wrong forum on the display problem but want to talk about it, maybe more people have the same problem with Nvidia GTX Titan.

      For me it was a "striped screen" if I use DisplayPort.

      With HDML became the first black screen when I look at the Try Ubuntu but if I clicked on Install became the black a little while ago, it worked as it should.

      After it finished installing I only got the choice to reboot but it worked right away. The boot straight into Ubuntu. Tried turn off the computer and start again. In the beginning, I get an Ubuntu screen where I can choose to start Windows (or Ubuntu).

      Have I done wrong now? Can I abandon the step to fix the boot loader? I seem to actually want a bootloader already.

      I apologize for any errors I write and if I have disturbed you. Have hard to read, write and understand after a stroke.

      Thanks again Gary

    Thanks Gary for your post. When I got into the "Install Ubuntu, click 'something else'" part, no matter what I did, Ubuntu kept showing my entire drive as one free space even though Windows was installed and I had performed the initial partitioning as instructed. Any advise would be appreciated.

  71. Gary, thanks for the article, very helpful.
    My issue was while fixing the bootloader in Ubuntu it keeps saying I'm using legacy booting mode while I'm actually using UEFI. As a result the fix was never successful, so my workaround now is to re-install Ubuntu in legacy mode and change the boot option to legacy to use Ubuntu.
    Have you ever encountered this before?
    Many thanks!

  72. Hey Gary. Great post. You definitely provided some details that I didn't see in any other explanations of dual boot installs. I have a question about one of them.

    Yours is the only install guide I've seen that recommends 3 partitions for Ubuntu. Usually it's only 2. One for the OS and one for the swap. My question is two parts.

    One: why do you suggest 3 partitions? and

    Two: If you are using 3, why does the / (root) partition for the OS need to be so big (50G)? I understand /home being large for all your data, and swap is standard based on DRAM. But I have seen install guides or help forums where others have said you need as little as 20G + swap, some even less I think.

    The reason I ask is that I have installed (and uninstalled) Ubuntu 14.04 alongside Windows 8.1 successfully using both DVD and USB methods.. AND using that 1st "install alongside" option in the installer menu was available both times. When I chose it, and clicked through the rest of the install (it does not show the "disk layout" section/screen) Ubuntu only created 2 disk partitions. A huge root, basically the entire remaining drive space minus the second one, which was the swap.

    A side note, I didn't have to do anything else after install. Meaning steps 7 and 8 were not needed for me. The installer completed and I was able to boot into both OS no problems. I think this has worked maybe because my CPU/MB supports both UEFI and BIOS. What do you think?

    BTW I am still looking for the perfect dual boot. See what I posted here for more details:

    1. Hi Dorothy,

      Thanks for the comment.

      To answer your questions:

      1. Why 3 partitions? Well I generally like to split out the root and home as this makes it easier when upgrading although the upgrade tool has made this easier. If I mess up my root partition I can usually just install over the top again leaving the home partition alone. The 3rd partition is for swap and whilst there is some debate as to whether it is still required I would prefer to have it and not use it than not have it and have some process unceremoniously crash my machine because I ran out of memory

      2. 50 gigabytes is quite high and probably a little too much but as disk space isn't a luxury anymore is allows for growth. You can easily get away with 20 gigabytes

      The default Ubuntu install does indeed create a large root and small swap space. This just means you have your operating system, applications, settings and data all in one partition. I just think it is cleaner to separate them out.

      I think with more modern machines the UEFI will be more mature and therefore the need to perform boot loader fixes will become less and less.

      There is still a lot of older hardware that has UEFI that performs badly and so that is why the fixes are required.

      It isn't an exact science I'm afraid.

    1. Hi Bill,

      thanks for the comment.

      As your machine originally had Windows Vista you probably don't have to do much at all.

      A lot of the steps covered here are to get around the UEFI boot loader and if you had Vista originally you will have a normal BIOS.

      What have you got working at the moment? Does Windows boot? Does Ubuntu boot?
