I am currently running Ubuntu with
grub-efi and rEFIt on a Macbook (8,3).
I'd like to have the option to boot Ubuntu in BIOS emulation mode as well. Is this possible?
I guess I need
grub-pc to write to the disk MBR (and hope that rEFIt will discover it), but I'm not sure if grub can handle bios and efi simultaneously. Please correct me if my assumptions are wrong.
I'm doing this because I've only been successful in enabling the integrated graphics in EFI mode, so I'd like to have external monitor support until I figure out how to enable the discrete chip. But that's a problem for another day.
