Hey guys, So I was in the process of trying to do a clean install on a 2.17GHz white macbook using the gray Mac OS X DVDs that came with my 2.1 GHz white macbook. I found out that each computer has their own unique disk. Problem is, I began erasing the harddrive, then I cancelled it after I realized it was a bad idea. Now I cannot boot into the computer, but am stuck in an endless loop of booting from the CD. I do have a copy of the 10.6 DVD, but cannot get the Gray disk to eject. What should I do? Thanks!
