Only wants to boot in safe mode
I got a macbook late 2006 and it only boots in safe mode. When i received it it came without OS X so i went to install Lion, but it would not work. Even in safe mode lion would not boot. I finally got my snow leopard usb to work, i powered on the macbook and held option, i selected USB boot and held shift as i pressed enter and it first displayed apple logo then the spinner then the blue screen and booted into installer, unlike when i booted without safe mode it went to apple logo then spinner then very fast flash of black screen and then white screen with nothing on it. Please help I'm not very new to macs but i don't know them as well as i understand PC so fell free to throw really complex solutions ill do my best to solve this.
oh and there is also this
