If I remember right, you have installed Mandrake 8? If so, the Mandrake installed created a Mandrake directory on your c: drive. This directory contains loadlin, the mandrake mini kernel, a loopback swapfile and a bat file. Run the bat file from dos and you will get into Mandrake. Once at bash prompt or wathever, type /etc/lilo, this will restore lilo.
I you have formatted your C: drive, as I suspect you did, you will find (on your Mandrake install disk1) the rawrite utility in the dosutils directory, and several linux boot floppy images in the images directory.
