I recently bought a Macbook Pro (mid 2009) from one of my friends and he had wiped EVERYTHING from the computer, drivers and all, he didn't save anything. So when I had received it and turned it on it was at a white screen. I took it to a buddy of mine and he did not have any Mac OS at the time, I had gotten one from another friend but when I put it in, its just a book camp and actually has no OS on it. So my buddy has installed Windows black XP 6 Ultimate for the time being but I cant even connect to the Internet or anything. What I am wondering is how can I get it back to the original lion OS without the disc and no internet connection to the laptop itself? I do know now I can switch back and forward from the XP and Lion, but when I click the "boot camp control panel" to select what system to start up the computer it only has windows... CAN ANYONE PLEASE PLEASE HELP..
