Hi guys, I have this problem, by mistake i put a Windows XP disk on my Macbook, boot from it and install the system formatting my harddrive. everything went perfect, but now i want to install OS X Snow Leopard so i put my retail disc, turn on the macbook hold down C Key or Option Key or any key and the macbook wont boot from it. try booting from a USB image of Snow Leopard, from the retail disc 10.5 Leopard and 10.6 Snow Leopard. i even connect the MacBook to an iMac by Firewire and did the installation by target and after installing the os x the system does not start at all. i put back the XP disc and boots perfectly from it. I dont know if its possible i deleted ant driver or damage the EFI on my Macbook i need to install OS X on it? anyone has this problem? how can i solve it?? pleas i really need HELP

You managed to insert, boot and install Windows by mistake. Amazing.

Try a PRAM reset. What color is the SL disk?

not by mistake.. the real mistake was doing this without knowing that will bring me this problems... its a retail disk its white and have a white Leopard on it.. i also try an retail disk of Leopard 10.5 and Tiger. anything... is not the disk cause i try it on 3 macs. all of them boots perfectly with the disk the problem here seems to be drivers or something like that. its like tray to boot a Vaio laptop with the Snow Leopard disk.

----------

already try a Pram Vram reset, and i try to fix the problem on single user mode.. anything!!! another idea?

Exactly which MacBook do you own? Maybe that computer only supports Mac OS Lion. Hold down Apple-R when it boots to try to boot into recovery mode.

No, its a White Macbook4,1 it cames originally with Leopard 10.5. Another thing is that every time i turn on the mac caps lock is on.
