Wow that was easy. There is a known bug in grub with x86_64. it’s currently broken on x86_64, and not only is tab completion broken in the current version (9.04), it seems that when you try normal command (’setup (hd2)’ anyone?) they don’t seem to get recognized either. Makes installing grub on your migrated drive a wee bit of a pain, especially since grub-install frequently installs something not entirely unlike a bootloader for you, but not like one enough to actually, you know, BOOT.
