Boot Into Ubuntu Live Environment
Simply reboot Windows 10 and a screen will appear with two options:
- Try Ubuntu
- Install Ubuntu
To start the installation click on the “Install Ubuntu” icon on the desktop.
The preparing to install Ubuntu screen now simply lists the option to download updates (which is only available after you have an internet connection) and the option to install third party software for playing MP3 audio and watching Flash.
If you have a decent internet connection then you might wish to install updates during the installation.
To connect to the internet click on the network icon in the top right corner and a list of wireless networks will be listed. Click on the network you wish to connect to and enter the security key when prompted.
You will need to click the back button on the "preparing to install Ubuntu" screen and then click continue again when you are back at the welcome screen.
If you have a poor internet connection then I would choose not to connect to the internet. You can update your system after it has been installed.
You can choose to install the third party tools for playing MP3 audio as part of the installation process now by checking the box or you can do it after the system has been installed.
Click the "Restart Now" option.
You will be asked to remove the USB drive and press enter.
Now when your computer reboots you will have options to boot into Windows 10 or Ubuntu.
