In this tutorial - 3 ways to enter BIOS when using Windows 8 or 8.1. In fact, it is a form that can be used in different ways. Unfortunately I have not had a chance to try all the ways described in the normal BIOS (however the old keys should work there - Del for desktop and F2 for laptop), but only on a PC with a new motherboard and UEFI However, most users of the latest versions of the system are interested in this configuration.
On a Windows 8 computer or laptop, you may have trouble entering BIOS setup, as with newer motherboards, as well as fast boot technologies implemented in the operating system itself, you may simply you don't see any "Press F2 or Del" sign or you don't have time to press these buttons. The developers have taken this point into account and there is a solution.

Enter BIOS with special Windows 8.1 boot options
To enter the UEFI BIOS on newer Windows 8 computers, you can use special system boot options. By the way, they will also be useful for booting from a flash drive or disk, even without going into the BIOS.
The first way to start the special boot options is to open the panel on the right, select "Options", then "Change computer settings" - "Update and restore". From there, open "Recovery" and under "Special Boot Options", click on "Reboot Now".
After restarting, you will see a menu like the one in the image above. There you can select "Use Device" if you need to boot from a USB mass storage device or disk and enter BIOS for this purpose only. If you still have to log in to change your computer settings, click "Diagnostics".
On the next screen, select Advanced Settings.
And that's it, click on "UEFI Firmware Options", then confirm the reboot to change the BIOS settings and after rebooting you will see the UEFI BIOS interface of your computer without having to press any additional keys.
