    READ THIS WHOLE THING BEFORE YOU ACTUALLY DO IT!!!! YOU MAY DISAGREE WITH THIS IF YOU ARE IN THE MIDDLE AND HAVE ALREADY ERASED!ok i know what to do, but u need to back up ur files onto ur time capsule, clearly you have one. ok so, insert your mac os x disc after ur backed up. boot from the disc, and then click continue and then at the menubar click utilities. select disk utility. go over to ur hard drive (not macintosh hd) and click on the partition tab. youre then going to click the drop down where it says currect,and ur gonna select 1 partition. name is Macintosh HD, and then click the drop down and make sure u select Mac OS Extended (Journaled). then click partition. ur gonna lose all ur stuff but thats why u have the backup. next install mac os x on macintosh hd again. once thats done, go to bootcamp and make the windows partition. go back to time machine and restore your computer from when u backed up. dont worry, this wont affect ur windows partition. ;)

    Just move about say 200GB in files off your main HDD into an folder on an external (since you have one), and try again. After it repartitions, just move everything back.

    What kind of advice is that?! Erase everything? :rolleyes:

    The problem you're having is that Boot Camp is lazy. Your files are spread out across your hard drive and so Boot Camp doesn't want to move a lot to create a partition.
    What you need to do is defragment your hard drive so that there is enough empty space for a partition to be made.
    PCs are Junk's method would effectively defragment your hard drive. All your files would be moved off, your hard drive wiped clean, and then moved back on again - but all bunched together.

    You have two options: PCs are Junk's method or download iDefrag:

    As said, if you have pretty much filled up your hard drive, then deleted stuff to make space, files are scattered everywhere so you need to defrag the hard drive (i.e. move all the scattered stuff together).

    You can pay for iDefrag, or the free option which isn't really the most convenient but reformatting your hard drive (reinstalling OS X) then partitioning once that is complete.
