On mandrake, Lilo WILL replace your windows boot loader.
An interesting note is that the NT loader does not reside on the MBR. It is on the boot partition with windows itself. All it does is creat a boot strap on the MBR to the loader wich is on the boot partition.
To restore this boot strap, use any Windows boot disk and type this at the DOS prompt
fdisk /mbr
that will restore the windows master boot record - for Win 9x - XP
