BOOTCAMP: "The startup disk cannot be partitioned or restored to a single partition"

I have a 2015 MacBook Pro 15 inch running the latest Mac OS Mojave update.


I have Windows 10 installed through BOOTCAMP but now I want to delete bootcamp & restore the Macintosh HD.


When I open Bootcamp Assistant it gives me the following error:


"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."

What should I do?

Maybe Loner T can help me out?

MacBook Pro with Retina display, macOS Mojave (10.14.1), MacBook Pro 15 inch 2015

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.
