Hi,

I'm trying to reinstall Mac OS X on my MBP using the original install disks. OS X was replaced by Ubuntu and now I'm trying to replace Ubuntu with OS X. When I insert the OS X CDs and try to boot from them, either by holding down the 'C' key or the option key and choosing the Mac OS X CD, the CD simply ejects, and then the computer proceeds to boot from the HD and into Ubuntu.

Any suggestions?
Thanks,
Anthony
 
Is it ejecting immediately, or trying to read it a bit first? Can the disk (or any other) be read normally when booted in Ubuntu? Could just be a dirty disk. Try washing it with a little dish soap and rinse thoroughly, and dry with a clean soft cloth.
 
I have a retail version of Leopard. It works fine on my Mac Mini, but my Macbook won't read it (either in OS or booting to it). It tries for about 30 seconds, then ejects the disk. The Macbook doesn't have problems with any other disk - just this one.

I had to burn a copy to a dual-layer DVD-R and the Macbook had no problems with the copy. YMMV.
