How can i remove the partition using BC assistant

See Remove Windows from your Mac using Boot Camp - Apple Support for reference.

In your specific case, given the current state, try


  • Step 1


diskutil eraseVolume jhfs+ BC1 disk0s3

diskutil eraseVolume jhfs+ BC2 disk0s4


diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s4

diskutil list


  • Step 2


If you see only disk0s3 as the last entry under disk0, then run


diskutil eraseVolume fat32 BOOTCAMP disk0s3


and retry removing the partition using BC Assistant only.

These two should not exist, when partitioning starts, otherwise it will fail.

I shouldn't proceed with step 2?

This looks fine.

Yes, you can proceed with step 2.
