Boot from an external CD or USB disk, e.g., Slackware Setup disk
# mkdir /dir
# mount /dev/sdaX /dir (substitute /dev/sdaX with your root device name)
# for i in /dev /dev/pts /proc /sys; do mount --bind $i /dir$i; done
# chroot /dir
Repair the boot loader, for example, for LiLO:
- # vi /etc/lilo.conf (if needed)
- # lilo -v
# exit
# for i in /sys /proc /dev/pts /dev; do umount /dir$i; done
# umount /dir
# reboot
