Um. Having the MBR get screwed up is one thing. But grub does rely on
the right files being on the right part of the disk for it to load the
second stage with the menu.

On the other hand, one can also install grub to a floppy. This then gets
around both MBR and primary /boot filesystem failure (assuming there's a
kernel safely on the "rescue" partition).
