I have done this many times and it should be easy to do.
First a grub.conf should look like this:
#
# Note that you do not have to rerun grub after making changes to this
file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,2)
#          kernel /boot/vmlinuz-version ro root=/dev/hda3
#          initrd /boot/initrd-version.img
#boot=/dev/hda
default=0
timeout=5
splashimage=(hd0,2)/boot/grub/splash.xpm.gz
#hiddenmenu
title Fedora Core (2.6.15-1.1833_FC4)
        root (hd0,2)
        kernel /boot/vmlinuz-2.6.15-1.1833_FC4 ro root=LABEL=/1 rhgb
quiet
        initrd /boot/initrd-2.6.15-1.1833_FC4.img
title Windows
        rootnoverify (hd0,0)
        chainloader +1


Needless to say your hdx,y designations will be different.
Then boot he system using Linux rescue or it should be possible on the
first CD to type : linux rescue at the prompt. Eventually it will
identify you Linux partition and you tell it that hdbx is the partition
you want to use. It will be mounted probably on /mnt/sysimage.
Then : chroot /mnt/sysimage
now run the following set of commands:
grub
grub> root (hd1,0)  <-- assumes you linux is on partition 1 of hdb
grub> setup (hd0)
grub> quit

You should be able to remove the Cd during the reboot that should work
to allow you to boot Linux or Windows.
