So I used a BOOTCAMP partition to run Windows 7 for a while, but I didn't need it anymore, so I deleted it with Disk Utility.


This partition is about 50 gb and I needed some extra space on my disk.


Now when I tried to make my Macintosh HD larger by drag the current box downside and apply it, it says, translated, that 'the partition has failed' and that it is because of 'the partition table cannot be changed because the control of the file system has failed'.


What should I do?

MacBook Pro, OS X Mountain Lion (10.8.2)

    Welcome to the Apple Support Communities


    Boot Camp volumes can only be deleted with Boot Camp Assistant. Macs use a hybrid GPT/MBR partition table when you use Boot Camp that must be deleted with Boot Camp Assistant, so maybe this is the reason of that problem. Open Boot Camp Assistant, create a new Boot Camp partition and delete it

    Clone your disk, repartition your disk, restore your clone. Then run Boot Camp again and read the directions this time.

    I have to select that I want to install a version of Windows 7 and that I wanna download the drivers for Windows.

    And when i go further I have to drag which amount of space I want for my partition.

    I apparently can't delete anything.


    Or am I doing something wrong?

    As Csound1 pointed out (and before feathers get ruffled) BCA altered the partition map in ways only it can undo.  You unsettled that tweak and you are in limbo needing deep-layered fix to the partition map.


    Csound1 is very experienced and I  listen to him, not try to find workarounds.

    I've already made a complete back-up with Time Machine.


    Could you please tell me step by step what I have to do.

    I don't wanna do anything wrong.


    Thanks in advance.

    And I know you explained it already, but I need more detail

    Download CarbonCopyClone (, $40) and make a bootable clone of your OSX on an external drive.  SuperDuper! (!, $28)is also popular in this forum.


    Ensure your external clone is proven bootable (hold the "option" key at startup to boot the clone.  Boot from the clone and use DiskUtility to partition the internal driv, then clone back to internal from clone.

    Okay. And is there a free option


    Like when I do a clean install of Mountain Lion firstand then restore my Time Machine back-up?

    I also have one external hard drive...

    Superduper seems for free, but then I probably have to erase everything on my current external time machine drive, before I'm able to using it for Superduper?

  • steve359 Level 6 (13,347 points)

    Bootable clones are good for when the main system dies (HDs will die eventually).  $40 for a cloning tool that makes incremental backups as well as still being bootable is a bargain if your data is *that* important IMHO.


    While not recommended, you can partition your external drive to 1/2 TM and 1/2 CCC.  But you lose both backups if youe lose that one drive.


    I keep 2 backup externals, one CCC and one TM.  Some people keep 2 CCCs and rotate one to a friend's house in case of fire or theft.

  • 1tio1 Level 1 (0 points)

    Okay, I'm going to try what you've said. Fingers crossed

    Your external will be erased, use CCC not SuperDuper (CCC can transfer the recovery partition, SD can not), 


    I suggest that you get another external rather than erasing the TM drive for this procedure.


    You will not be restoring from TM you will be restoring the clone.
