When i try to uninstall the Mac OS X Leopard, the install disc just get pushed out after i restart the Mac. AND, nearly 90% of the times i try to put the Install CD in my computer it just gets pushed out. I have tried the "Hold C butten when starting the computer" I want to install it with the same disc that i installed leopard with. I got a Mac Book Pro with Leopard. And i also want to install Boot camp when i reinstall the computer. Pliis. I need to reinstall the computer. I have to get it to work. I need it at school!
