Sometime there are situations when you need to enter BIOS, for example to change boot order of devices, for OS reinstall, or for loading some utilities from bootable media. And you cannot enter to the BIOS with simple key press on keyboard, for example that can happen if you have enabled fast boot in BIOS settings, or if you need to enter BIOS on tablet.

After reboot select Diagnostics
