I have the 13 inch macbook pro, the baseline version. I wanted to play The Sims 2 in windows so I started my bootcamp and put in my windows xp disk. It started to install but then said disk error - press any key to restart. Pressing the keys didn't work so I had to do a hard shut down. It was going really slow when it booted up and I have no idea how to get the disk out. How do I do a full wipe of the hard drive and reinstall everything?
