It would seem that I missed his intent. I seem to recall the word
"backup" and ran with that. Now that you have explained the situation so
well, I think DD is a viable solution in this case.
But there is an easier, better one. Simply bring his own disk in and put
it in the machine. Most have a place for two, but only populated with
one. Install Linux on the second disk and overwrite the MBR with the
LILO or GRUB entry. That way you have a dual boot machine.
Another way is to use Partition Magic to resize the Windows Partition,
creating space for a FAT32 partition and space for Linux if a second
disk isn't used. the FAT32 partition is used to shuttle data back and
forth and is where Boot Magic can optionally live.
It may even be possible to do all this with an external USB disk if you
can figure out how to boot it via the BIOS.
