Q: Can't uninstall Boot Camp - El Capitan/Windows 10

I have a 2015 MacbookPro running El Capitan with an 80GB Boot Camp (Windows 10) partition on a 1TB drive.

I want to delete Boot Camp and reclaim the space for OSX. All guidance that I can find says to do it via Boot Camp Assistant, but when I open it & hit "continue" I get the message...

 

The startup disk cannot be partitioned or restored to a single partition.

The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Bot Camp Assistant for installing Windows.

 

...and I can't go any further.

 

Suggestions?

 

Cheers

CurlyBananas

MacBook Pro (Retina, 15-inch, Mid 2015), OS X El Capitan (10.11.4)

A:

If you erase the partition, it becomes Apple HFS, which Bootcamp cannot remove. You will need to use

 

1. Backup OSX and all your files - Use Time Machine to back up or restore your Mac - Apple Support .

2. Boot into Internet Recovery (Command+Opt+R) - OS X: About OS X Recovery - Apple Support .

3. Click on Utilties -> Disk Utility and Erase your internal whole disk.

4. Restore OSX and your files - Use Time Machine to back up or restore your Mac - Apple Support .

 

This requires a separate external disk which can accommodate TM backup - Backup disks you can use with Time Machine - Apple Support .

    You do not have any lost space. Can you post the output of

     

    sudo gpt -vv -r show /dev/disk0

    I am having the same problem. I have tried erasing the Bootcamp partition, then trying to remove, but the - button is always grayed out. I you want to see my results from Terminal just ask

    Thanks

    Please see the steps for a TM Backup/erase/restore in the previous post. Same problem as Aiddog10 .
