Why do you believe "GRUB thinks boot partition is on (hd0,2) even though
it has been installed on (hd0,0)"? If you run grub interactively as
root, does it find things that should be in /boot on (hd0,2)?
Example - (from my FC1 system):
[root@radar0 root]# df

Hard to say, do you have more disks? - see below...

This shows hda, but is it the only disk? "fdisk -l" should show all the
disks if you don't specify /dev/xxx.
Example:
[root@radar0 root]# fdisk -l

Not enough info provided to get a clue. Should also have asked for
output of df and /etc/fstab, as well as /boot/grub/grub.conf
