Something broke during the upgrade. Try to rerun the installer, choose the 
upgrade again, and let it quickly figure out that nothing needs upgrading. 
Another attempt will be made to reinstall grub. See if that fixes it.

If it's still broken, boot the installer and choose the recovery mode. 
chroot /mnt/sysimage, then rerun /sbin/grub-install.

If it's still broken, your device map is probably wrong. Grab the contents 
of your menu.lst, while you're in the recovery shell, as well as the 
contents of /boot/device.map, and explain what storage devices you have in 
this machine.
