    I had that problem with the hal.dll file while trying to install windows XP on my mac. So I had to follow this guide and make the partition 32 gigs for windows, which I find about 10 gigs too big for my needs.

    Does anybody know if it's possible to change the partition size? I heard leopard could do it, but disk utility doesn't seem to let me do it. I formatted windows in NTFS, so maybe that's why.

    Any help is greatly appreciated, thanks!

    Re-partition Boot Camp

    Hi! Have you discovered already how to change the partition size of your boot camp? If so, please let me know too. Thanks!

    You could shrink NTFS volumes with almost any Linux live CD. But you cannot add the extra space to your Mac HFS+ partition.

    You would probably have to clone your Boot Camp partition (Winclone comes to mind), delete the Boot Camp partition, recreate it with a smaller size then restore your Winclone backup to the new smaller partition.

    Heres what I would try... Go into windows and shrink your partition size.

    To do this:

    Click Start -> Right click on "My Computer" -> Click "Manage" -> Then "Disk Management"

    Once it loads your disk setup, right click the portion that is used by your bootcamp and click "Shrink Volume" and make it 10GB smaller.

    Then go back to OS X and use disk utility and I assume it will let you use the free space to expand the OS X partition!

    Hope this works.

    Just make it 32 GB... It is the easiest solution. Besides, it isn't to big to ask for.

    "...(Winclone comes to mind), delete the Boot Camp partition, recreate it with a smaller size then restore your Winclone backup to the new smaller partition."

    I don't think Winclone allows the restoration of the disk to a smaller partition than the one it came from, or at least it wouldn't for me (even if the partition wasn't full). I'm not sure Dan73's suggestion would work perfectly either as the smaller created partition might not be exactly where you want and stop the expansion of the mac partition.

    No, what I would do is combine their approaches. Load windows and follow dan's advice to shrink the partition. Then load OS X and create a winclone of the shrunk partition.

    Next get rid of the bootcamp partition altogether with bootcamp utility. The entire disk will then be mac formatted. Then recreate a bootcamp partition slightly bigger than the small partition you wincloned. Finally reverse winclone windows into the new smaller partition.

    hope that makes sense
