Help!

I'm an idiot. I can't boot my Dell. Here are the particulars: Dell Latitude D600 notebook. 40 gig hard drive with the following on it:

[Lilo bootloader] WinXP_copy1, WinXP_copy2, Knoppix_on_HD, FAT_Data_Partition

Here is what I did: I tried to use Norton Ghost to back up WinXP_copy1 while booted into WinXP_copy1. When you tell Ghost to backup, it seems to leave something on the MBR to tell itself to boot into some kind of virtual partition it creates. In the past I have imaged both copies of WinXP but always while booted into WinXP_copy2 - so it didn't damage Lilo. This time, for no reason in particular, I tried to ask the 'copy1' Ghost to do it, and when I boot all I get is

"Missing Operating System"

I also tried to load Partition Magic and as has happened in the past, it says it can't even read the partition table (this usually means that I have trashed the MBR somehow).

The good news is a still have my Knoppix live CD available. Question: given that I need to reinstall Lilo, is there any way to do it from the Knoppix live CD?
