Thanks for your response. I've decided to do clean installs of a triple boot system with leopard, XP and ubuntu, and to use an external hard drive to transfer data between the two computers.
He would I go about reinstalling vista on my old PC without having to purchase a new serial though? I'd like to sell the computer with a fresh install, so should I deactivate it, wipe the hard drive and install vista?
I know this last question is a little off forum, but I look forward to your response. Thanks!
