If the grub bootsector is being written to /boot, then if I made only
that disk bootable, it should boot, right? I did try this and it did
not work. I checked grub and it says it is installed at /dev/hda,
whereas /boot is located at /dev/hdb1. So if i did copy the bootsector
but grub isn't installed on /dev/hdb1, then I'd end up with a
completely nonbootable system, correct?
