Ok, I installed the windows version of Boot Think 2.3. It allows my OSX and Windows 7 to boot. BUUUT... when I get into OSX the keyboard and mouse don't work. Also there is this quick and repetitious noise coming out of my speakers. Can't tell if it's frozen or not as I have no testable input method. But it does boot so that is an improvement. The instructions for Boot Think besides being kinda vague (at least for me) since they only seem to apply to using it from within OSX. The windows version has no gui and I can't really figure out how to configure anything. I'm going to go play with it. If anyone can offer any assistance on this I'd be quite pleased. Off I go.
