Sorry if this has been posted on here before or im in the wrong area. I have a MacBook Pro A1211 I got off Craigslist. It needed a new logic board and hard drive so I got both. My problem is I just found out the hard drive has windows on it and when I power on the MBP all I get is a white screen. My question is is there a way to get windows off that hard drive while its installed in the MBP? I've tried every command I could find online to push when I power on the MacBook but it does nothing. I bought a copy of snow leopard 10.6 factory sealed and put it in the super drive but it just spins for a while and then stops. The fans constantly run also but I'm new to MacBook so I don't know if that's suppose to happen. I got the disk management to come up once by holding down option and power on but it didn't give me the option of choosing the SuperDrive and I can't get it back up. It's almost like the keyboard isn't working. If there's any suggestions y'all can give me I'd appreciate it.
