I've just got my Macbook and I'm now trying to get XP to work. I got to the point where is says to Press Enter or R or F3. I tried pressing enter, about 20 times. I rebooted, it went into trying to install again, and I had the same problem. What should I do? (Note: The partion for XP isn't showing up on my mac. Is it supposed to? The space is gone that I allocated for).
