Yesterday I tried to install Win10 through bootcamp, but it couldn't install it on the premade partition. Eager as I was i meddled with the partition scheme during the installer but with no result.
While in pain that I couldn't get my dual boot right, I wanted to reset the partition-table by using bootcamp, only it gave me this 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'm currently stuck using DiskUtils to delete the partitions and make my HDD whole again. But it won't work.
This is the output from diskutil list
/dev/disk0 (internal, physical):

My Mac model is MacBook Pro mid 2015.
The desired goal is to lose all partitions, including the "Backup" partition, which I can not seem to delete using the Disk Utility application. Eventually, I want to have a single Mac partition, which is required by the Boot Camp Assistant application to install a Windows 10.
Any advice?
Thanks

I would assume the same procedure would be followed as the answer posted to this question "Merge Partitions with Disk Utility in El Capitan Gives operation Failed error".
In other words, the commands would be as shown below.
I would advise executing the command
diskutil list
after entering each of the above commands. If something unexpected happens, send me a comment.
