hello guys,
i tried to install snowleopard to my pc and i was preparing a thumb drive to do it. downloaded netkas pc efi 10.6 and i accidently run in on my mac. so now when i open my mac just gray screen and nothing happens. when i hold option button, there is nothing to boot.
I put snow leopard 10.5 Disc and an error page occured.
Maybe i wrote something wrong in terminal while preparing the thumb drive i dont know.

Any idea how to fix this?
