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

Hi, all. I'm trying to remove Windows from my Mac to free up more space. However, when I try to remove it the conventional way (by using Boot Camp), I get an error that says "The startup disk cannot be partitioned or restored to a single partition." It goes on to say "The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows." I already tried erasing the disk and unmounting it in Disk Utility. Any help would be appreciated.

MacBook, macOS Sierra (10.12.5)

This should work in your case as well.


Run (only once)


diskutil eraseVolume jhfs+ BC1 disk0s3

diskutil eraseVolume jhfs+ BC2 disk0s4

diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s4

diskutil list


If you only see disk0s3, then


diskutil eraseVolume fat32 BOOTCAMP disk0s3


and now run BC Assistant and click on Restore/Remove.

Hello LonerT,


I thought this worked but I guess I accidently tried to reinstall bootcamp again because it gave me an error. What is the correct command this time? Sorry for making you type all of this and thank you so much for the help.

Hi Loner T,


Thanks for the quick responses. I'm having the same error. In my case, I never actually managed to install Windows. Rather, the error resulted from me not completely finishing the partitioning process after deciding I might want to allocate more space (originally, I only allocated 50 GB). When it asked for my admin credentials to finish the process, I decided to just click cancel and redo the process, but ran into the error. This is what I see from diskutil list:

Just want to make sure I do this correctly. Could you provide the commands I need to do so?
