On anything that has SecureBoot enabled and/or that doesn't have a CSM, I just hold down Shift while clicking restart in Windows. Not all systems I've run across have a key to bypass into UEFI Setup directly and in some extreme cases I've actually had to remove the HDD to access it (to at least turn SecureBoot off). Good thread. Keep up the good work.
well I use ASRock here, then is one option to enter uefi directly this file is AsrRuefiSetup(v1.0.3).exe size=1.266KB download on Asrock.com works with Windows 8.1 and 10 I hope that help someone here
I appreciate a lot your contribution. But the point here is to enter to UEFI setup utility just by using keystroke combinations as you can see at the first post, not by using extra software. Imagine this scenario: you want to enter to UEFI settings but Windows 8.x/10 is NOT bootable anymore.
