Problem in recovering GRUB

Hi, I'm writing this for my friend. I had installed FC3 in his system, dual booting with Win XP. Recently, he had to reinstall his XP. It was pretty difficult, as the setup would freeze when trying to detect hardware (probably due to the presence of the 'alien' EXT3 partitions). Finally, he had to format his primary partition with Partition Magic and installed Win98 in it. He then upgraded it to XP. Now he wanted to recover his FC3. I followed the standard procedure to recover his GRUB with the FC3 install CD. I noticed that his partition names had changed. The 'root' partition which was hda9 had become hda7, and 'boot' had changed from hda8 to hda6. But I made the necessary changes in 'fstab' and 'grub.conf'. Following the procedure, the root partition was mounted under /mnt/sysimage without errors. I gave the 'chroot /mnt/sysimage' command and then gave 'grub-install /dev/hda'. But the following error was displayed:

"/dev/hda does not have any corresponding BIOS drive."

I tried to install grub in the boot partition i.e. /dev/hda6. Still the same error.

"/dev/hda6 does not have any corresponding BIOS drive."

I then tried to upgrade his FC3 to install GRUB. Then the setup recognized the previous installation and installed some additional packages. It then reported that bootloader was not installed and that a new bootloader configuration was needed. When it came to the installation of bootloader, the setup reported that GRUB cannot be installed as I had not installed the kernel packages. Well, I had'nt.

Now, what is to be done to recover his GRUB? I suspect that the Partition Magic has done something nasty. But the Linux file systems are intact (only the designations have changed) and the old grub.conf is still present. Therefore, it should be possible to reinstall GRUB throught the standard recovery procedure, is'nt it?

His system is an Athlon XP 2000. I would be most thankful for any little help and guidance as I'm still a newbie.
