To restore the mbr to the original you normally do '/sbin/lilo -u', but in your case you have LILO installed in two places; so I think you need to include the device name '/sbin/lilo -u /dev/sda' I got this from 'man lilo' -u [device-name] Uninstall lilo by copying the saved boot sector back. The '-s' and '-C' switches may be used with this option. The device-name is optional. A time- stamp is checked. Anita
