Short version
What options are there to enter the UEFI firmware settings when rebooting into them is not possible?
Long version
The situation is as follows: My computer runs fine, but when I reboot the computer, the computer will freeze up. My backlighted keyboard will flash, one of my coolers (I suspect the GPU cooler) will shortly run on max and stop doing that and after that nothing. I can get out of this by pressing the reboot button on my PC. I have not given this matter much attention, because turning the computer on and off works fine, as does sleeping, so it is seldom an issue.
Now I want to change something in the UEFI settings (because I suspect my virtualization options are not as they should be ). My first hunch was to press some key when the computer is starting up, but this does not work: the first things that I see after the monitor turns on is the Windows log in screen. I found the regular procedure (in short, press shift when pressing restart in the Windows menu and pick troubleshoot/advanced/uefi settings). The computer starts to reboot, but the problem in the previous paragraph kicks in. After I get the computer to reboot properly again, the option to go to the UEFI settings is forgotten and I am presented with the regular Windows login screen.
The next steps I need to take are more time intensive and I wondered what my best course of action would be. Is there an alternative way to enter the UEFI settings? I probably should fix my restarting problem, but the (preliminary) research I have done so far suggest I might need to update the firmware of the motherboard or reinstall Windows, both which I would like to avoid for now.
