Recover free space from bootcamp setup prematurely ending

Question

I was setting up bootcamp, and while partitioning it crapped out and the mac restarted.  The partition is not showing up the disk utility or the bootcamp assistant.  Running the command below, from reading other forums, I do see the 55 GB as free space, which I was allocating for the bootcamp partition. How do I recover the disk?  Should i try to delete and then see if disk utility sees it then recover?  I don&#x27;t want to do anything more to royally screw it up even more. Thank you.CoreStorage logical volume groups (1 found)|+-- Logical Volume Group 5EC6E7DD-4816-4E24-9F2E-095ADCA741F7    &#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;    Name:         Macintosh HD    Status:       Online    Size:         250140319744 B (250.1 GB)    Free Space:   55009370112 B (55.0 GB)    |    +-&lt; Physical Volume A60B4361-939B-4059-B9CB-00E889AB0673    |   ----------------------------------------------------    |   Index:    0    |   Disk:     disk0s2    |   Status:   Online    |   Size:     250140319744 B (250.1 GB)    |    +-&gt; Logical Volume Family A8237E33-FB14-4F46-8B21-E50C80717CBC        ----------------------------------------------------------        Encryption Type:         AES-XTS        Encryption Status:       Unlocked        Conversion Status:       Complete        High Level Queries:      Fully Secure        |                        Passphrase Required        |                        Accepts New Users        |                        Has Visible Users        |                        Has Volume Key        |        +-&gt; Logical Volume D770C83F-CF75-412A-8043-7BF06C0AE4F1            ---------------------------------------------------            Disk:                  disk1            Status:                Online            Size (Total):          194778628096 B (194.8 GB)            Revertible:            Yes (unlock and decryption required)            Revert Status:         Reboot required            LV Name:               Macintosh HD            Volume Name:           Macintosh HD            Content Hint:          Apple_HFS

Please post the output of the following Terminal commands.diskutil listdiskutil cs listsudo gpt -vv -r show /dev/disk0sudo fdisk /dev/disk0The "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.

1. Run Disk Utility Repair, and check if you can extend the Macintosh HD.2. Boot into Internet Recovery.3. If that does not work, you can revert the CS volume to JHFS+, using diskutil cs revert disk1 and check if DU will allow you to recover it. 4. If that does not work, backup OS X using Time Machine, erase your internal disk and restore from Time Machine.

Thank you.

Is it working as you want it to?

darkvise · Answer

As you instructed, I ran "diskutil cs revert disk1", which decrypted the drive.  When I opened disk utility after the process finished, I saw that I now have 85GB of available space instead of the 30GB.  thank you.
