Turn Off Fast Boot
Click the link which says "Change settings that are currently unavailable".
Scroll down the page until you see the option “Turn on fast start-up (recommended)” and turn it off
by unchecking the box.
Click “Save Changes”.
Now you might be wondering why I am recommending turning off a recommended option.As previously mentioned you can’t boot from a USB drive whilst this option is checked. In addition to this I feel that the option is a bit cloak and dagger. What it says is that if you have the option checked your computer will load faster.
The trouble is that once your computer has finished booting it will still go and do all of the things that it missed out on whilst booting to make it load faster but it will do it quietly in the background. This will use up resources until it has completed. In reality your start screen might appear more quickly but it hasn’t really booted and quicker.
