1.  Boot off live CD.
2.  Mount you linux partition.
3.  Chroot to your Linux partition.
4.  Run grub at the chroot'ed prompt, entering these 
    commands, replacing P with the number of the 
    partition Linux is on.  Ie, if Linux is on the 
    first partition, replace P with 1:
      # grub
      >> root (hd0,P)
      >> setup (hd0)
      >> setup (hd0,P)
      >> quit
