I have not done this.

First thought...are the partitions in similar /dev/hd?x
e.g. /boot on both in /dev/hda1 and /dev/hd?1

second thought...can you boot CD and use linux rescue mode to mount the
partitions and chroot before you install grub?

third thought...when you installed grub, you installed to hd1 which
would suggest the first hard drive located after the primary
master...did you switch hard drives around so that it would now fail? If
so, could you do the CD, chroot and install grub again?
