Hey guys I am really dumb with this stuff so I will put it out flat. My Macbook went to a grey screen and nothing would get me out of that. I put in the disc to reinstall or whatever. I got on the installer, selected language, accepted software agreement, and then where I select a destination, nothing is detected. I can't really figure out what to do. Is there anything anyone knows about this sort of thing? Maybe it has been answered, but I am fairly illiterate in this topic.
