Installing grub to dual boot

[Brad De Vries]

Everyone/Anyone, I could use some assistance here.  I'll start with a
little history to make the current state and desired direction a bit
clearer:

1) Got a laptop with win2000 pro from work with a 20GB HD formatted FAT32.
2) Ran the disk defragment and error checking tools so everything was "clean."
3) Booted Knoppix and successfully ran "parted" to reduce the FAT32
partition from 20GB to 10GB.
4) System failed to boot win2000 due to error "NTLDR is missing." 
Figured I'd fix that later.
5) Installed Fedora Core 3 into the newly freed up 10GB.
6) System booted fine into FC3 and the crowd went wild.
7) Verified the grub.conf had an option to the win2000 side and rebooted.
8) Chose the win2000 option from the grub menu but it failed to boot
due to "NTLDR is missing" error.
9) After much googling, hunting, and trying I was able to fix the
win2000 boot problem but in doing so overwrote grub from the MBR.
10) Figured that since the original problem (see step 4) came from
changing the disk partition size, all I'd have to do is boot the linux
side and run grub-install.
11) I've booted from the FC3 disk in rescue mode and Knoppix and
neither will successfully run "grub-install /dev/hda2".  The command
hangs.

So the current state is that I can boot win2000 fine (hda1,) I have
FC3 installed (hda2) but I can't re-install grub so that I can boot
either O/S.

What I'd like is to have grub appear at boot time and allow me to
choose either FC3 or win2000.  How do I re-install grub to allow that
to happen?

Thanks,
Brad.
