I have an April 2010 White Macbook, and I recently installed Bootcamp using Windows 7 32bit. I have a problem with the Wi-Fi, it doesen't even reconize it. But that's the least of my concerns, I can't boot back into OSX Lion. Ive tried the option key but all that comes up is a lock. It looks like it wants me to type in a password but ive tried all of them. Any help would be great.
