How about grub-install '(hd0)' ? Does that work?
When cloning a disk, you have to remember the MBR contains block maps of
where on the rest of the disk to read stage2 for grub. After that it
can read filesystems and doesn't care if files move. So doing a
grub-install on a drive after messing with the partitions is a good
idea.
