I gotta tell you guys, I wouldn't install/alter an OS on a PC that
wasn't mine. You're asking for trouble if something goes wrong.
I'm not saying you couldn't do this and get away with it, but the
dreadful *what if* something went wrong and you couldn't restore
Windows? Would the shop hold you accountable? An uppity clerk who didn't
understand that Windows was still there, just couldn't accessed, might
get angry. It's probably the worst case scenerio, but why risk it?
Instead of fully installing Debian on the machine, why not just boot
Knoppix or (my fav.) DSL? It's quick, it doesn't touch Windows at all,
no one will every possibly know it was there once you reboot.
