If you’ve upgraded to Windows 10 and then something happens and your PC won’t boot and Startup Repair does not work, which it rarely does. Then you need to create a Windows 10 Install Disc or USB Flash Drive to boot from and repair your Windows 10 Installation.
Microsoft has done a good thing here. They’ve created a Media Creation Tool to create an Install/Repair Disc or USB Flash Drive for Windows 10.

This will walk you though creating Install Media for your Computer.
Nice Tool to have!
