Fail.
Since Boot Camp doesn’t officially support Windows 7, the app wouldn’t install in Windows 7 on my Mac. I’m sure it could have been solved by manual installation of drivers etc, but I just couldn’t be bothered. It felt like destroying my poor Mac :P
Also, the lack of a right mouse button was reaaaaally frustrating in Windows. It works without much problems in OS X, because it’s designed for it. But Windows definitely is not.
So my Mac is back to its single partition state with just OS X, but I do have a nice backup of it :) And I also learned a lot about file systems. I guess everything has something good in it!
Yay learning :D
