Basicly you need to boot up with a boot disk to get back into Linux and re-run the /sbin/lilo to re-install the boot loader. Assuming you haven't changed any of the partitions it should work. If you don't have a boot disk, you could boot up with the first install disk and enter the option 'rescue'. This will get you into the rescue mode, in which the root directory structure is in ram.
There will be a menu option to mount your system under /mnt. Select that and then 'cd /mnt' and then 'chroot /mnt' so that the root directory is back like it should be. Next I would execute 'bash -l' to read in your actual startup script, which will set up your normal root paths and aliases. This will allow you to run vim for instance and not just 'vim-minimal'.
Now cd to /etc and make sure the /etc/lilo.conf is in good order. If it is execute '/sbin/lilo'. Watch what is printed as it works, because if there is a problem accessing one of the partitions, or an error in lilo.conf, then the MBR will not be updated.
The reboot and keep your fingers crossed.
If you get back into Linux later, there is something you might want to do. With the 2.6 kernel, or som 2.4 kernels, the kernel is too big to fit on a floppy. But you can produce a rescue cd (about 4 MBs in size) by executing as root the command 'mkrescue --iso'. This will produce a .ISO file that you can burn to disk and use the next time you can't boot up normally.
Some distro's have a mkboot --iso command option which would be nice to have, but Mandrake's mkboot script doesn't have that option presently.
