Boot from a Linux rescue CD - the install CDs for most Linux distros can be
used in some form of "rescue mode". I'm pretty sure Fedora can do it, but I'm
not sure how.

What you want to do is get to some form of command prompt and mount your
Linux partition. Mounting it is easy enough:
  mkdir /mnt/oldlin
  mount /dev/hda1 /mnt/oldlin
  chroot /mnt/oldlin
  
Now you're sitting at a root shell from the perspective of your preinstalled
Linux system. Chroot is in effect making the kernel tack "/mnt/oldlin" on to
every path that gets accessed. The shell thinks you're accessing /, but in
effect you're accessing your own local system.

Now type:
  /sbin/grub-install /dev/hda
  
That'll reinstall GRUB into the MBR of the primary master hard drive and
should fix the references to the disc partition that stores the GRUB config
file and second-stage loader. Hit Ctrl-Alt-Del, eject the CD, then see if
GRUB starts up (it should).

I've done this with LILO a few times, but the same concept should apply to
GRUB.
