I recently erased my bootcamp partition through Disk Utility. I couldn't use Boot Camp Assistant and got the following error:

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 erased the partition and not it's empty. I am trying to merge it with my mac OS partition so I can get all my space back but now I am getting this error in the terminal

The given partitions are not on the same whole disk

when I use 

diskutil mergePartitions JHFS+ ODMac disk0s2 disk1

How can I get my storage back fully on my MacBook Air?

Here is my diskutil list output:

  • Can I assume it would be OK to delete the 2.2 GB disk0s4 partition? Most likely this partition is between your main macOS volume and the free space you want to recovery. Although, you have not presented enough information for anyone to determine this.

  • What more information do you need?

  • Basically, the values in the GUID partition table (GPT). The command is sudo gpt -r show /dev/disk0. If you are using High Sierra, you can only run the command from macOS recovery. In other words, you have to restart and hold down the command-R key. This command shows exactly where the free space is on the drive.

You have a 2.2 GB partition (disk0s4) on your drive. I am not sure this partition is even formatted. It is also possible the partition is not mounted. If not mounted, then the partition will not show up in the Finder. Anyway, this partition needs to be deleted before you can recover your missing free space.

The command below will delete this partition.

diskutil  eraseVolume  free  n  disk0s4

Once the disk0s4 partition is deleted, the next command can be used to recovery your missing free space.
