lilo failed--HELP

[Michael J. Schweppe]

I installed a second drive as a primary slave today on the Win 98 box.
and loaded Red Hat 7.1.  I set lilo to install on the mbr of hda [the
Win drive].  Upon reboot after the start up bios type stuff I get a
blank screen with the letter "L" and that is it.  I tried typing and
nothing seems to work.  Presently I was able to get to C:\>, but I do
not know what to do now.  

My guess is that there must be a way to get to the mbr and kill lilo
so at least I can get Windows back and perhaps try again.

Anxiously awaiting any responses.

Thanks,

Mike
