Dear Jonathan, after I thought about your problem for a while, it came to my mind, that my first advice was not correct and you rather might succeed when you try ´grub-install --root-dir=/dev/hdax /dev/hda´, where x is the number of the partition, that contains / and /boot. It might be necessary to mount the /-partition first and then refer to it with --root-dir=/mnt/hdax (e.g. when operating from a live-or rescue CD). Alternatively simply boot into the System on hda, if possible, and just ´grub-install /dev/hda´. This way the Grub images should be installed to the actual /- directory. Perhaps someone else on this list can give better advice without guessing.
