Chroot

• Boot from a rescue 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
