ok well fairly new to mac and im trying to help a friend fix his macbook he tried to install and as soon as it starts. I get a chime and then apple right after that i get "you need to restart" message its in multi language so he said it was working fine til he tried to install snow leopard which he had downloaded according to him this is what he did

and restored it then he got the error i told him he did it completely wrong and his mac doesn't work with any boot keys i tried every boot command as well using the install disk and nothing at all seems to work so any suggestions or help.
