Cannot restore Macbook Pro OS.
I have a mid-2010 Macbook Pro. I am trying to reset the OS. I currently have Mac OS X Lion 10.7.5 (11G63) installed, but the disc I have is Leopard.
When I try and reset it to factory conditions (following the instructions on the support website) the boot screen goes gray and shows a message instructing me to manually shut down and turn on the computer. It is the same image I have seen associated with kernel panic, but it only happens when booting from the disc.
I recently installed new 8GB RAM, but I have tried with both sets of chips and see the same result.
MacBook Pro (13-inch Mid 2010), Mac OS X (10.7.5)
