The problem is that memtest86+ (the one we're using behind the memtest boot
option) can't boot from UEFI (also see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=651562#10). So I'm afraid we
can't really do anything about it. Maybe we should add "BIOS-mode only" or so to
the affected boot options in grub to clarify that?

The:

| error: file '/boot/grub/x86_64-efi/vbe.mod' not found.

is strange though.

PS: Either the video capture file was forgotten to be attached or stripped of by
the BTS. :)
