I'm not sure about lilo, would trust James for that. But you could put a Microsoft MBR back on the disk's MBR by booting a recovery floppy and typing the command "fdisk /MBR". I rather afraid that it could be more than the MBR that is damaged, but if it's only that then this would get Windows back and you would at least know where you stand in trying to get lilo reinstalled.

I would also think you might look to Norton for some support on this, it seems likely that they have run across it a time or two before.
