If you have a failed driver or update and Windows 10 will not start the recovery option will pull up eventually....
In the Troubleshoot menu, click Advanced options. The
Advanced options menu will give you several options: System Restore,
System Image Recovery, Startup Repair, Command Prompt, Startup Settings,
and Go back to the previous build. Click Startup Settings to change Windows' startup behavior.
In the Startup Settings menu, click the Restart button to restart your PC. Your PC will now restart.
When your PC starts up, you'll see a light blue screen with the Startup
Settings menu. You can now choose an option using your keyboard (number
keys or function keys). To start up in Safe Mode, press 4 or F4. To start up in Safe Mode with networking, press 5 or F5. To start up in Safe Mode with the Command Prompt, press 6 or F6. If you change your mind and decide you don't want to boot into Safe Mode after all, hit Enter to boot normally.
