I lost my restore DVDs for my C2D Macbook. I have the restore DVDs for my older CD macbook but when i try to use those it give me the message "ALERT, this software cannot be installed on this computer". Is there a difference between the CD and the C2D restore DVD? Can I walk into Apple Mac Genius bar and ask them to barrow a copy so I can restore my macbook? I do have any warranty left on it. Thanks any help is appreciated.
