Create SefeMode in Windows10


Nothing gets you out of Windows trouble like Safe Mode, which is why its inexplicable that you can no longer enter it by pressing F8 or Shift+F8 at boot. Although its still available in Windows 10, you have to boot into Windows first, then either restart holding the left Shift key or via an option within Update & Security in the Settings app. Neither method is helpful if your PC cant boot into Windows in the first place. 

You cant get around this, which is why its helpful to create a boot time Safe Mode option before trouble arrives. 

Hit Win+x and select Command Prompt (Admin), then type 

bcdedit /copy {current} /d "Windows 10 Safe Mode" and hit Enter. 

From the Start Menu type 

msconfig, 

run System Configuration in the results, and navigate to the Boot tab. 

Highlight the Windows 10 Safe Mode option you just created, tick Safe boot and select Minimal under Boot options and - if necessary - reduce the Timeout value so you wont be inconvenienced - the minimum is three seconds. Tick Make all boot settings permanent (in fact you can simply return here to delete the Safe Mode entry) and click OK.

You can repeat these steps, substituting suitable names in quotes at the Command Prompt, to create shortcuts for Safe Mode with Networking (tick Network rather than Minimal in System Configuration) and Safe Mode with Command Prompt (Alternate shell).
