I have noticed on my Qubes desktop that after a period of time I am no longer able to see the BIOS boot screen, nor boot into the BIOS during startup. I can clear my BIOS to make BIOS access available again. This has happened a few times, with BIOS access disappearing after a few weeks or so.
Question 1: Is my system being hacked?
Question 2: After clearing the BIOS to regain BIOS access I can no longer boot into Qubes (drive not shown). Is it possible to clear the BIOS and regain access to my Qubes system without having to reload Qubes?
