Q: Missing part of my storage on my hard drive, bootcamp install failed.

Earlier today I was trying to install Windows 10 on my Macbook Pro Retina (Late 2012)(El Capitan), and after my computer restarted to go to the windows page so I could install it, i found that there was no "BOOTCAMP" partition for me to select to install the windows program on. My computer had 128GB of storage capacity so i used 32GB for the Windows partition and kept 88GB for my Mac OS side. When i logged back into my mac os user, i found that i only had 88GB of storage. I went into disk utility and there is no BOOTCAMP partition. it only brings up my mac user with its 88GB of storage. Its like the other 32GB just vanished. I have tried everything I could find online, but it was no help. If you have a solution on how to get my storage space back that would be great and also if you had a fix for what i was doing wrong when i tried to instal windows 10, that would be great also.

MacBook Pro with Retina display, OS X El Capitan (10.11.1)

    Can you post the output of the following Terminal commands?

     

    diskutil list

    diskutil cs list

    sudo gpt -vv -r show /dev/disk0

    sudo fdisk /dev/disk0

     

    The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

    This is where your "stuck" space is hiding.

     

    A. The less-labour-but-more-time method...

     

    1. Backup OSX using Time Machine - Use Time Machine to back up or restore your Mac - Apple Support . Please see Backup disks you can use with Time Machine - Apple Support for types of disks that can be used with TM.

    2. Use Internet Recovery (Command+Opt+R) - OS X: About OS X Recovery - Apple Support. Erase your whole internal disk.

    3. Restore the system from the backup in step 1 - Use Time Machine to back up or restore your Mac - Apple Support

     

    B. The more-labour-less-time method is shown in this link - Lost storage space on my mac .

    Thank you! Any idea why that space on my hard drive became unavailable while i was trying to do the partition for windows?

    BC Assistant partitions the drive in two steps. Reduce the CoreStorage volume and then create a FAT32 partition in the free up space. If the second part fails, you are left with the current situation.

    Why did the second part fail? I did everything in the instruction correctly.

    The second part is considered an 'atomic' operation from a user perspective. You only see that the disk is being partitioned. You have no visible control over it directly. This has happened in several cases, especially on El Capitan. It could have been prevented by verifying/repairing the disk, but the console messages indicating the possible causes of failure may be lost by now.

     

    Run Applications -> Utilities -> Console and put disk in the search box and check the messages for any errors.
