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.
