I had a failing IDE HD as /dev/sda, so I installed 10.3 on a new SATA drive /dev/sdb and was booting from it until I removed /dev/sda. The SATA drive is now /dev/sda, but it won't boot, just the cursor on the top of the screen.
Booted from DVD to rescue, altered fstab and menu.lst was changed from (hd1,0) to (hd0,0), still won't boot and grub commands give unrecognised device string errors.
menu.lst now says
gfxmenu (hd0,0)/boot/message
No luck.

Rescue isn't as easy as it used to be. The solution in
http://lists.opensuse.org/opensuse-factory/2007-04/msg00048.html might be
your solution.

Did all that, /dev/disk/by-* tree is sound, looked up "info grub" and "info grub-install", nothing makes any sense.
# grub-install /dev/sda1
# grub-install /dev/sda
# grub-install (hd0)
# grub-install (hd0,0)
grub> setup --stage2=/boot/grub/stage2 (hd0)
grub> setup --stage2=/boot/grub/stage2 (hd0,0)
and other combinations using /dev/sda and /de/sda1 all give "Error 12: Invalid device requested".
The odd thing is that when I had the IDE drive installed (/dev/sda) with the SATA (/dev/sdb), it booted off /dev/sdb, after removing the IDE drive, it refused to boot. "fdisk -l /dev/sda" shows the bootable flag on /dev/sda1. I have / and a swap partition on the drive.
I can't think of any incantation that will make grub do anything.

The only way I could recover successfully in a similar situation is described here. Seems grub as a program itself gets its device info directly from the partition table only:
