Q: Bootcamp partition trouble

Used bootcamp to install windows 10 on my mac.

 

Mac is running OS X El Capitan.

 

Right at the end of the partitioning the computer froze, through I would leave it for a little while, may be doing what it's meant to.

 

Left it for about half an hour, nothing changed so i decided to reboot. Once I rebooted, my hard drive is missing the 32 gb I was giving to the partition and not a single program can find the new partition. Bootcamp and disk utility don't recognise it's there. Disk utility shows my mac storage as being 120gb but there only being the mac partition and it being only 88gb. I assume the computer freezing during the partition program is what caused this, what I need is a solution. I can't use bootcamp to delete the partition because bootcamp doesn't even recognise a partition exists. When I use first aid from disk utility it says there's probably a problem with the partition map. How can I solve this, I've been to every forum and post I can find and short of taking into apple I don't know what else I can do.

MacBook Air, OS X El Capitan (10.11.5)

    From OS X Terminal, please post the output of the following commands...

     

    diskutil list

    diskutil cs list

     

    If BCA fails during partitioning, it can leave some disk space in an unknown state.

    This is where your 'lost' disk space is hiding.

     

    Can you use Boot Camp Fail.  Genius Bar struggling as a reference and use the diskutil cs resizeVolume and diskutil repairDisk commands?

    These are the responses I get:

     

    diskutil cs resizeVolume 32137502720 B:

    32137502720 does not appear to be a valid Core Storage Logical Volume UUID or disk


    diskutil repairDisk 32137502720 B:

    Usage:  diskutil repairDisk MountPoint|DiskIdentifier|DeviceNode

    Repair the required layout and components of the partition map of a whole disk.

    Ownership of the affected disk is required.


    I don't know if I've done this right.


    Thanks.

    Please boot into Internet Recovery and ensure you have a backup. The UUID came from your specific output.

     

    diskutil cs resizeVolume 43806D1C-FC4D-4C7D-88A0-CBDDDE56E1DB 0g

    diskutil repairDisk disk0

     

    Please post the output of both commands. In Internet Recovery, you will need to use Utilities -> Terminal and run these commands. Use Copy (Command+C) to copy the entire output, exit Terminal, start Safari, and Paste (Command+V) the output as a reply in this discussion.

    Your Mac's EFI partition was modified by the Windows installer and it's Partition type GUID was modified, so OS X complains.

     

    The best tool to fix this is GPT Fdisk - https://sourceforge.net/projects/gptfdisk/ .

     

    We can do it in two different ways.

     

    1. Install OSX on external volume - How to install OS X on an external drive connected to your Mac - Apple Support, install GPT Fdisk on this external disk. Update the GPT, or,

    2. Boot normally, install GPT Fdisk and update the live disk, which may require additional reboot.

     

    Method 1 is a lot more work, but safer, then Method 2. My recommendation is to use Method 2.

    You will be updating the partition type GUID of the disk which you are booted from using Method 2.
