The funny thing is that I had been considering just the night before whether to disable the Windows boot altogether and make it boot straight into Linux. I so wish I'd done that, because I've have loved to have seen what he'd have done with a Linux command line.
Cheap substitute: Place the C/D ROM drive at the top of the boot drives and leave a Knoppix bootable C/D in the machine. He can still get to the Windows drive but it's more of a hassle.
This might also limit the damage possible by powering down improperly since Knoppix accesses Windows drives as read/only drives.
