Just to clear up the EFI misconception, Debian can be installed on EFI
computers. I run it on three of my own-- 2 Acer desktops and 1 ASUS
laptop. I use rEFind as a boot manager, as it it very straightforward,
and does a very nice job with all OS entries. I understand that there
are instructions for installing Debian with GRUB only floating around,
but I don't find it necessary.
