I want to delete my Windows partition and regrow my Mac partition to use the whole disk. But when I click Restore in the Boot Camp Assistant, it says:
Your disk could not be restored to a single partition.
An error occurred while restoring the disk to a single partition.
I'm using Mac OS X 10.8.5, on a mid-2009 MacBook Pro.
MacBook Pro (13-inch Mid 2009), OS X Mountain Lion (10.8.2)
launch diskutil and run 'repair'
it should fix any issues and then try to restore the partition
No, Repair actually made the problem worse.
Repair did log some improvements to the Mac partition, but resulted in the Windows partition disappearing entirely. As I plan to sell the computer, I ended up deleting all partitions, formatting a single HFS+ partition over the whole hard drive, and reinstalling Mac OS X. Had I wanted to keep the computer, this would still present a problem.
I had this problem today and discovered an easy way to fix it.
1. First, open "Disk Utility" under the Applications/Utilities folder.
1. Select the Windows partition on the left and go to the "Erase" tab. Pick "Mac OS Extended (Journaled)" and click the Erase button. This will reformat the Windows partition into a normal Mac partition.
2. Select the disk on the left and and go to the "Partition" tab. Pick the newly erased partition in the partition layout and click the "-" (minus) button to remove it.
The likely problem is your sharing settings. Go into System Settings and remove all of your sharing checkboxes and then re-try. Worked for me.
You are so amazing! Thank you so much! Try and get a job at apple because this worked!!!!!!! Thanks you saved my poor computer!!!!!🙂
worked for me as well after having the same issue removing windows 7 from partitioned disk.
Tried that, but it didn't help. :-(
Are you running Yosemite? I am. My Disk Utility doesn't let you Remove anything from the left-hand pane, only 'Unmount.'
You should post a new discussion to avoid being ignored due an older discussion. 😉
This helped me once I selected ERASE and not ERASE FREE SPACE.
I also encountered same problem.
I had to remove windows 10 due to space issue. When I tried to remove windows partition got same error "Your disk could not be restored to a single partition.". However, boot camp (version 6) had done its job. Next screen was to start partition and select windows ISO.
The issues I still saw:
1) Windows partition space allocated still displayed: In Disk utility, i did not see windows partition, but under parent drive, I saw windows space. I removed it and my hard disk was restored into single partition (Windows 10 was already removed via Boot camp 6)
2) When I press Option key while reboot, I still see Windows Option along with Mac
Can anyone help me how to remove winodws option from reboot? Not sure if its Boot camp 6 bug? I really dont want to format and reinstall Mac

Please see the third page of Can't resize Macintosh HD partition and how to mount the EFI partition and clean up. If BCA fails or removes Windows partially, this is expected.
Your problem sounded just like mine, I also did not see the "Windows Partition" in Disk Utility. And I also wanted to remove the Windows option on reboot (I had two windows options from accidentally downloading bootcamp numerous times). The initial suggestions did not work.
This ended up working for me: https://www.youtube.com/watch?v=WmdsLfLAO20
