Even though this disc is wrong for that machine, so the test isn't really valid,
it's worth mentioning that *any* time you see this screen, it's a bug in the
CSM - the BIOS emulation layer on top of UEFI is completely failing to comply
with the El Torito standard for CD booting when it sees multiple boot sections
on a CD. Rather than implementing correct support to select which boot
section to use, this version of the CSM, which is shared among Apple machines
and other vendors' alike, presents all of the choices as a menu instead.
Awesomely the keyboard driver not being present is a /second/ firmware bug. On
some machines it is present, and on those selecting "1" will work and continue
booting as if on a BIOS machine.
Apple have fixed this on newer hardware, but I don't think they've ever pushed
a fix back to this generation.
