Lost Space After Removing Bootcamp Partition

Hi guys,

I think I've got similar problem. I was removing boot camp partition (windows 10) with boot camp assistant and it was interrupted. My Macbook Pro (13' early 2011, el capitan) just restarted.

Now I've got one partition (macintosh hd) which I can see in disk utility, but ~70GB of disk space is missing. Can you help me with recovering it or do I have to do clean install?

They are now unallocated space on your HDD, I'd guess. Look at your partitions in Disk Utility. Take a screen snap and post it here:

To post screen shot do this:

1. Press COMMAND-SHIFT-4 which will change the cursor to crosshairs.
2. Hold down the mouse button and use the crosshairs to select the part of the screen you wish to capture.
3. Release the button and the image will be saved to your Desktop.
4. Click on the Camera icon in the toolbar of the forum message editor.
5. Drag the image onto the Choose File button and click on the Insert button.

Yosemite converts your JHFS+ volume to a CoreStorage Volume (also used by FileVault2). BCA partitions the drive and rearranges the Recovery HD to be GPT3 (GPT1 = EFI, GPT2 = OSX) and Bootcamp/Windows is GPT4 (GPT is GUID Partition Table partitions and the numbers are ordinal positions in the GPT).

If you do not use BCA to remove this partition, the disk space is not returned back to the CS volume.

Please post the output of the following Terminal commands.

diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

sudo commands require your password, which is not echoed back to you. It may also warn you about improper use and potential data loss, if abused.

You will need to revert the drive from CoreStorage to Standard HFS+. Open the Terminal in your Utilities folder. At the prompt paste the following:

diskutil list

Press RETURN. This should list your current Unix disk structure. You should see an entry for a Volume named Macintosh HD. It should show a disk ID of disk0s2. Please verify that is correct. If not then tell me before doing the following.

At the prompt paste:

sudo diskutil cs revert /dev/disk0s2

Press RETURN. Enter your admin password when prompted. It will not echo to the Terminal window. Press RETURN, again.

Reboot the computer. Open Disk Utility, select the outdented entry, and click on the Partition tab which should display your partition structure as it would appear normally. You should now see a 75 GB block of space that you can add to your Macintosh HD volume.

Notice the 76GB Free Space in the diskutil cs list output.

Unless Kappy has alternative suggestion, I suggest the following (the last 'b' is bytes).

diskutil cs resizeVolume <UseTheLongStringUUIDAboveTheMacintoshHDLine = DB68...> <UseTheSizeInBytesUnderTheLogicalVolumeGroupEntry = 250140434432b>

diskutil cs resizeVolume

Usage: diskutil coreStorage resizeVolume

lvUUID|MountPoint|DiskIdentifier|DeviceNode size

Resize a logical volume, which is one of one or more disks that consume storage

out of a logical volume group. The logical volume group will have more or less

available space after this operation, if it was a shrink or grow, respectively.

Example: diskutil coreStorage resizeVolume

11111111-2222-3333-4444-555555555555 10g

In my command I have the "DB68..." string, which is your Logical Volume. You are trying to use the Logical Volume Group "5455..." which already has the 250g size. It is confusing to have the LVG and LV, both named as "Macintosh HD". 😉

Change the last number to 250g and test.

Yes, you can try 249g.

😎 Excellent.
