Boot from the rescue CD.
Let it mount your fedora.
It will be mounted as /mnt/sysimage
do the following:
chroot /mnt/sysimage
grub-install --recheck /dev/sd?
where ? is a or b or c ...etc.
If you need it to be installed on the partition
instead of e the MBR, then
grub-install --recheck /dev/sd?N
where N is the partition number, such as 1 or 2 or 3 ...etc
After it finishes, you may want to add to it the ability to boot windows.
If so, then append to it
title Windows XP Pro
rootnoverify (hd0,0)
chainloader +1
assuming your windows is on sda1
Goof luck.
