Hi folks I am new to Apple, having just bought a seconduser MacBook. I found that the previous owner had loaded Windows XP Pro on it. The Macbook is a 2ghz Core 2 Duo, with 1gb of ram and an 80 gig sata hard drive. (A1185?) I received the Macbook boxed, with it's user guides and original OS X 10.4.6 CD set. I would like to re-install OS X, but when I try to boot from OS X CD 1, I see 2 folder icons with a question mark, the laptop then proceeds to boot Windows XP. I also tried a reboot holding down the option key, this got me to a screen showing icons for the hard drive (with XP) and the CD drive (with OS X CD 1) If I choose OS X, the cd drive spins up, but after a few seconds the MacBook proceeds to boot XP again Could anyone advise me what the problem might be? I assume either the CD set is not for this Mac, or else the optical drive has a problem reading it? The cd disc itself is in perfect order, no scratches or signs of damage. Also, when in Windows XP, I checked the optical drive with various CD and DVD media, it seems to have no problem reading these. Please go easy on me this is my first Apple. I just don't want XP on it! lol Regards. Den.
