I can't erase my BOOTCAMP partition in MacOS Mojave

Hi guys.

I have an iMac 2017 (Core i7, Fusion 3Tb, Radeon 580 8Gb, 16Gb)

One month ago, I installed Windows 10 in my iMac for one project but I don't need it now, I tried to erase bootcamp partition with diskutill app and diskutil terminal... But I cannot erase it..

My scheme partition is:

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme 121.3 GB disk0

1: EFI EFI 314.6 MB disk0s1

2: Apple_APFS Container disk2 121.0 GB disk0s2

/dev/disk1 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *3.0 TB disk1

1: EFI EFI 209.7 MB disk1s1

2: Apple_APFS Container disk2 2.3 TB disk1s2

3: Microsoft Basic Data BOOTCAMP 724.4 GB disk1s3

/dev/disk2 (synthesized):

#: TYPE NAME SIZE IDENTIFIER

0: APFS Container Scheme - +2.4 TB disk2

Physical Stores disk0s2, disk1s2

1: APFS Volume MacOS 1.7 TB disk2s1

2: APFS Volume Preboot 46.4 MB disk2s2

3: APFS Volume Recovery 510.4 MB disk2s3

4: APFS Volume VM 5.9 GB disk2s4

I´m try this:

diskutil eraseVolume jhfs+ MyVolume disk1s3

Started erase on disk1s3 BOOTCAMP

Unmounting disk

Error: -69879: Couldn't open disk

What can I do?

Thanks

I´m resolved my problem...

Use CMD+R to enter recovery and erase bootcamp partition but diskutil show an error and botcamp partition and 700Gb missing, I cannot see in disk app or diskutil:

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme 121.3 GB disk0

1: EFI EFI 314.6 MB disk0s1

2: Apple_APFS Container disk2 121.0 GB disk0s2

/dev/disk1 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *3.0 TB disk1

1: EFI EFI 209.7 MB disk1s1

2: Apple_APFS Container disk2 2.3 TB disk1s2

/dev/disk2 (synthesized):

#: TYPE NAME SIZE IDENTIFIER

0: APFS Container Scheme - +2.4 TB disk2

Physical Stores disk0s2, disk1s2

1: APFS Volume MacOS 1.7 TB disk2s1

2: APFS Volume Preboot 46.4 MB disk2s2

3: APFS Volume Recovery 510.4 MB disk2s3

4: APFS Volume VM 2.1 GB disk2s4

So I think that free space of AFP Container disk2 is lost.

Try to resize AFPS container with all free space --> diskutil apfs resizeContainer disk0s2 0

And work ok :-) all lost space is in AFPS Container

No... bootcamp assistant was my first option but doesn't work... if the solution was easy, I don't ask the question :)

When I try restore MacOS partition using bootcamp assistant, type my MacOS password and the assistant does nothing... 12h with assistant windows "restoring"

Only the Boot Camp utility used to create that Boot Camp partition can remove it, release that storage, and update the drive partition map non-destructively. The only other method is to erase the entire drive.
