Need help regarding partition

Hi guys,

I need help. Recently i was trying to use Boot Camp Assistant to install windows on my MacBook Pro (2015 / 13" / 256GB) running MacOS X 10.13.5. It showed some error that it couldnt be installed so i cancelled the process. The system said that it will rollback the system to the original state but it took too long so i closed the bootcamp assistant.

And now my MBP drive are partitioned, i want to merge the disk to the master disk, i used disk utilities and it failed. I even tried to use the bootcamp assistant but it showed a 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 Boot Camp Assistant for installing Windows.

Attached some screenshot about my disk drives right now.

Please kindly help since im not an expert in this field.

Thanks

MacBook Pro (Retina, 13-inch,Early 2015), macOS High Sierra (10.13.5), Storage Partition

Notice the BC1 entry in the left pane. Did you run the following part?

If you only see disk0s3, then

diskutil eraseVolume fat32 BOOTCAMP disk0s3

and now run BC Assistant and try to Remove/Restore.

Hi,

Unfortunately when i try to copy-paste the text output from terminal i get some error message saying the message contains invalid character.

So i copy-paste it to textedit and put it on dropbox

Dropbox - diskutil apfs list.rtf

Run

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 try to Remove/Restore.
