I have a relatively new iMac (Christmas 2009) and am trying to install windows 7 on boot camp but I get an error saying that windows must be installed on an NTFS partition... problem: I have no idea what that is or how to get it. I thought maybe that has something to do with PAL vs. NTSC but both the iMac and the window 7 software were bought in Germany (where I live) so I just don't know. Last year I also bought and installed Parallels on my iMac but never really used it. The reason I'd like to install windows is because I really need to learn AUTOCAD and it runs on windows. I just mention it because I guess I have the option of using Parallels (though it still seems to have an old version of Vista on it and I can't get rid of it). Uhg!! As you can see, I have no idea how to install windows properly and its kind of driving me crazy. Any help would be greatly appreciated.
