(1) I expect that you mean something you could run from DOS, since
    (a) you'll just have installed Win@#$!! and now can't boot Linux, and
    (b) Win@#$!! won't allow you to get at the mbr (except 'fdisk /mbr'),
    which means you'll have to reboot from a floppy in any case, no?
(2) You _did_ make a boot floppy didn't you? For my RH4.2:
    # cd /boot
    # dd if=vmlinuz of=/dev/fd0

I would just boot from that floppy and run lilo.  Looks about as simple to
me as a trick DOS utility to clean your Windows.
