It's not easy.
First, boot from the cd1. Enter "linux rescue" at the lilo prompt.
This will mount the root partition to /mnt/sysimage (or something like).
Mount /boot partition to /mnt/sysimage/boot :
mount -t ext3 /dev/hda? /mnt/sysimage/boot

Disable exec-shield :
echo 0 > /proc/sys/kernel/exec-shield

Run grub-install. For example :
grub-install --root-directory=/mnt/sysimage /dev/hda

Take this pieces of advices very carefully ! Backup /boot partition.
