I just bought a Macbook Air and have a huge problem. I need windows on it and all I have is an old xp home upgrade edition cd without either SP1 or SP2. I would be happy to buy the full retail windows 7 when it comes out but that wont be until Oct 22nd and I need to use Windows right away. I could buy an old window 98 upgrade on the web for $20, but Ive read that that I cant use the 98 disk during installation. Also Ive read that I can only use xp home with SP2. What is the best advise you guys can give me?
