Boot camp stuck on 'Roll back partitions'

Question

The situation came up when I was trying to install Windows 10 via boot camp. Something went wrong so boot camp said it is rolling back partitionsHowever its stuck on this screen for quite some time and I would like to have my disk space back. Any suggestions?diskutil:/dev/disk0 (internal):   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:      GUID_partition_scheme                         121.3 GB disk0   1:                        EFI EFI                     314.6 MB disk0s1   2:                 Apple_APFS Container disk1         76.0 GB    disk0s2   3:       Microsoft Basic Data OSXRESERVED             8.0 GB     disk0s3   4:       Microsoft Basic Data BOOTCAMP                37.0 GB    disk0s4/dev/disk1 (synthesized):   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:      APFS Container Scheme -                      +76.0 GB    disk1                                 Physical Store disk0s2   1:                APFS Volume Macintosh HD            46.9 GB    disk1s1   2:                APFS Volume Preboot                 21.8 MB    disk1s2   3:                APFS Volume Recovery                521.3 MB disk1s3   4:                APFS Volume VM                      1.1 GB     disk1s4/dev/disk2 (disk image):   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:                            CCCOMA_X64FRE_EN-US... +4.7 GB     disk2

Stop the BCA process, because it may never complete. Reboot and rundiskutil eraseVolume jhfs+ BC1 disk0s3diskutil eraseVolume jhfs+ BC2 disk0s4diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s4diskutil listIf you only see disk0s3, then diskutil eraseVolume fat32 BOOTCAMP disk0s3and now run BC Assistant and try to Remove/Restore.

When I tried to implement the command of &#x27;diskutil eraseVolume jhfs+ BC1 disk0s3&#x27; and &#x27;diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s4&#x27; for whatever reason the terminal said&#x27;Unable to find disk for disk0s3&#x27; and &#x27;Could not find disk for disk0s3&#x27;Thus when I rebooted my computer and went to BC assistant I clicked continue but the message popped up saying &#x27;The startup disk does not have enough space to be partitioned.&#x27;Is there something I am missing from the process?diskutil:/dev/disk0 (internal):   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:      GUID_partition_scheme                         121.3 GB disk0   1:                        EFI EFI                     314.6 MB disk0s1   2:                 Apple_APFS Container disk1         84.0 GB    disk0s2   3:                  Apple_HFS BC2                     36.9 GB    disk0s4/dev/disk1 (synthesized):   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:      APFS Container Scheme -                      +84.0 GB    disk1                                 Physical Store disk0s2   1:                APFS Volume Macintosh HD            46.9 GB    disk1s1   2:                APFS Volume Preboot                 21.8 MB    disk1s2   3:                APFS Volume Recovery                521.3 MB disk1s3   4:                APFS Volume VM                      1.1 GB     disk1s4

Excellent. disk0s3 was already marked for pending deletion, which caused the little hiccup.
