A simple trick to avoid using the MS-Windows/NT boot loader is to ensure that the primary MS-Windows/NT partition is less than 2GB in size. Then when you install GNU/Linux let LILO take control as normal and create LILO entries for both MS-Windows/NT and GNU/Linux.
In all cases MS-Windows boots from /dev/hda1 (or perhaps /dev/sda1 for a SCSI disk) which is drive C a primary partition and the active partition.
