I tried to reinstall Mac Osx on my Macbook and all it does is keep restarting..Its completely stuck in a cycle and will not stop...It just shows a grey screen and restarts..What can I do to stop this or eject the CD..Thanks

Do you use the grey Restore DVD, that came with that MacBook? Is that DVD in good condition? Do you have access to an external optical disk drive (ODD)? Do you have access to a Mac OS X 10.6 Snow Leopard Upgrade DVD?
