From there, you can access all the available Safe Mode options. To compensate for this, Microsoft configured the operating system such that if there is a persistent boot problem, Windows 10 will automatically boot into the Startup Settings menu. Microsoft’s justification for disabling the F8 key is essentially that the UEFI-based computers boot up so fast that people would never be able to press F8 before Windows starts. You can no longer press F8 during the Windows startup sequence to access the black-and-white Advanced Boot Options menu system to select Safe Mode. By now, you’ve probably noticed that Microsoft has removed the standard method of accessing Safe Mode in Windows 10. Safe Mode is a troubleshooting option that starts Windows in a limited configuration to make it easier for you to isolate problems caused by device drivers and other configuration problems. Sooner or later, you'll probably need to boot Windows into Safe Mode-but in Windows 10, you can't rely on the good old F8 approach.
