Here's the situation. I've borrowed my girlfriend's macbook for the weekend, and I have a hankering to see how well vista will run on here before I make the decision to buy myself a macbook, or a macbook pro. Anyway... I may die if it is returned to her in any way other it left. I would like to make a backup of this computer on to a USB external hard drive before said experiment, then restore the macbook as if no foreign OS ever touched it. Can I do it, n' how?
