He also will need to modify /boot/grub/device.map and
/boot/grub/grub.conf to point to the correct devices before he runs the
grub-install.
>From the description given device.map probably has mapping for hd0 and
hd1. The mapping for hd0 will need to point to the fc2 drive (/dev/hda)
and remove the mapping for hd1.
Then in grub.conf change everything that points to hd1 to point to hd0
instead.
