I heard from multiple Youtube videos and walkthroughs that said that Windows took 4gb, so I made a 24gb partition. After installation, I go to "Computer" (c: drive), and it says 9gbs free of 24gbs. I'm using a MBP 2.53 w/ 9600, and installed Windows 7 RC 64bit. What happened? How can I see what's taking up all that space?
