    Hope someone can help:

    I tried to use Bootcamp to load Win on my MacBook but it failed at some point at the creating a partition stage.

    I have now been left with a 32G partition on my MacBook SSD that I can't get rid of.

    It is most infuriating, I'n not a guru and have tried Disk Utility to erase the unwanted partition and resize the SSD but nothing will budge it.

    Can anyone suggest my next course, or any course, of action??

    Thanks in advance.

    If you can't use disk utility you might have to reinstall Mac OS from scratch to get rid of it.

    Would be a good idea to make your second windows partition at the time of reinstallation.

    32GB unknown partition? That's just Apple's way of doing 32GB RAM on their MBPs.









    Sorry, couldn't resist. :D

    Thanks for the reply robotica.

    I understand that I have the 'Nuclear Option' but was hoping for someting a little less drastic.

    I was hoping that someone could suggest software that could help me.

    Good one - I would settle for that if I could use it that way. 32G of seperate storage isn't much use to me on a half empty 512G SSD :)

    Show what "diskutil list" (without quotes) prints in Terminal.

    Wait, I thought that "everything just works" ?

    You now want me to use a terminal?

    I have the same issue with my 2012 MBP. I gave 80gb to Windows and it wont give it back :(

    My plan is to wait for my new MBP to arrive than hit the nuclear option and wipe it all (then sell it).

    All very resonable except I don't want to sell my MacBook Pro.
    It can't be beyond the wit of man to sort this

    Back up your OS X partition to an external drive then wipe it and copy it back

    I do have a 'Carbon Copy Clone' backup but it is untested, I guess I won't really know until I try it.

    I assume I boot into recovery mode, use DiskUtil to erase & format the SSD, boot from my external backup and away I go??

    Sounds easy when you type it out.

    The partition table is quite messed up for a simple BootCamp installation. I think it can be fixed by diskutil but I highly recommend you make a backup first, it's not just simple precaution like given every time, it's a precaution that your partition table looks different than it should and there will likely be problems.
    Also you'd need to get rid of Recovery partition and use Internet Recovery if something goes wrong thereafter (you can merge only adjacent partitions and Recovery partition prevents this).

    Here’s a plan of action that’s guaranteed to work:

    1. Use CarbonCopyCloner to create cloned bootable backup of your Mac partition on an external drive. CCC will also clone the recovery partition, as well.

    2. Boot up from the cloned backup.

    3. Open Disk Utility and RE-initialize the internal drive.

    4. Now, RE-CLONE the contents of the cloned backup BACK TO the internal drive. Also re-clone the recovery partition.

    5. Now, boot from the internal drive. It should have just -one- partition (HFS+) “all Mac”. The failed BootCamp partition will be gone (wiped out when you re-initialized).

    Yes, this takes a little time, but it is GUARANTEED to do the job.

    All these replies with a long process. Why not use Disk Utility and have it restore it back? Comes free with your Mac.

    The problem is the Macintosh HD volume is in core storage and cannot be resized. Try this in Terminal and wait for it to finish. That will turn off core storage on the main volume. Then go back to Disk Utility and see if you can remove the 32GB volume at the bottom and resize Macintosh HD.

    Code:
    diskutil cs revert "Macintosh HD"
    This should not destroy any data, but backup first just to be safe.

    Because with Recovery between Macintosh HD and Windows partition you can only increase Recovery and not Macintosh HD. I doubt you need 30G Recovery partition.

    There are two ways to access Disk Utility, one is through the Recovery option you mentioned and the other through the OS itself. Try the later one.

    Also, Bootcamp helps restore an uwanted partition.

    Ok, It is now sorted so a big thanks to all of you who contributed, it gave me the confidence to sort it.
    By the way Weaselboy, you suggestion didn't help but thanks all the same.

    To get my whole partition back I followed Fishrrman's advice, many thanks fella. Im to at 100% capacity, no unwanted partitions and a CCC backup that has now been tested.

    Flush with success, I will now apply this known working backup to my main iMac, a computer that has successful been upgraded since from its original installation of Mountain Lion, but is now is feeling a little slow.

    Once again VMT
