Any ideas?
Yes, it isn't actually booting in EFI mode. I don't think this will be
an issue with Debian because by the time the Debian installer runs the
system has already decided whether it is booting UEFI or legacy BIOS.
Possibly I could be wrong about that, in that possibly your
motherboard's firmware doesn't see the install media as EFI bpptable so
is falling back to legacy BIOS.
I think I'd have another go looking through the BIOS settings to ensure
there's no way it is set to legacy booting or fallback to legacy
booting.
