I was check around for a little bit just to see what the easiest way to boot safe. I came cross
few few of them. But, all of them pretty much sounds the same .so, here a few different
ways to access safe mode.
1. Settings
From the desktop, click on the Start button, then click on Settings.
Select Update & Security > Recovery.
Under Advanced Startup, select Restart Now.
After the device restarts, you'll be prompted with a list of options. Select option 4 to boot to
Safe Mode. If internet access is required, select option 5 to boot to Safe Mode With
Networking.
2. Logon screen
At the logon screen, hold the Shift key down and click on the onscreen power button >
Restart.
Upon the device restarting, you will be prompted to choose an option. Click on Troubleshoot
> Advanced Options > Startup Settings > Restart.
The device will restart a second time, this time displaying a list of options. Select option 4 or
5 to boot to Safe Mode or Safe Mode With Networking, respectively.
The three categories that you can start your computer in safe mode are from a blank or
black screen, the settings menu and screens or from the sign in screen. All have their own
way to get to safe mode booting but will all end with the same result thankfully. For the
settings screen you can either press the windows key in combination with I or press the
windows key by itself and navigate through the settings to recovery under update and
security. You press restart now and after you get the options, you go to troubleshoot
advanced startup options and enter safe mode. that would be the more simple one
thankfully. If you cant open settings, then you need to be on the windows screen for your log
in, there you press shift in combination with the power button. This will lead to the above
troubleshoot option with the advanced system startup. Select that and you will once again
have the option to boot whilst safe mode is activated. Finally, from a black or blank screen
you need to enter winRE which will be a bit of a tedious process. This will require you to
repeatedly turn your device off and on by holding the power button down for ten seconds
each time. You must hold the power button down every sequence when turning the device
on and off until you get to the recovery environment. This will allow you to select
troubleshoot, advanced system startup, and enter safe mode.
