Yesterady I got the file folder with the "?" on my Macbook 2.0 CD. I took it to the apple store and the Genius just put his ear to it and said my hard drive was broke. So I went to Frys and picked up a new 250gb 2.5'' SATA drive. I put the new HD in and then the OS X install disc and it gets to "preping install..." then says "this software cannot be insalled on this computer." Disc Utility sees the hard drive, the partition is locked, it won't let me install OS X on it. Also under disc utility my superdrive shows up as a 4.8gb HD. Someone help, the whole reason I did this was so I wouldn't have to be without a laptop with finals week coming up.
