Hi guys, I've been trying to install windows on my mac (10.7 mid-2010 27") for a while now and have been getting the error message saying that it cannot partition the drive because there are some fies that need to be moved and that I need to format my drive as a single Mac OS Extended (Journal) Volume. I already looked through a ton of forum posts and everyone said a defrag will take care of the issue, so I defragged and compacted my drive and I'm getting the same result. I've attached a picture of iDefrag so you guys can tell me if I did something wrong. At the very end of the drive is a volume header followed by 4 white/grey blocks, I'm not sure if they're supposed to be there or if they're causing the issue (I assumed that it should have 2 headers; one for start and one for end). Any advice would be greatly appreciated. I also have no idea how to format my drive as an extended volume, so if that's what I have to do (I'd rather not, but am willing) I could use some steps on that too. thanks!
