Latest Windows Update Messed Up Bootcamp/Windows

Been running Windows 10 in bootcamp on my iMac (Mojave 10.14.2) for some time now and regularly do macOS and Windows updates. Tried to start Windows a few days ago and got the 0xc0000225 error. /dev/disk0 did not show a "bootcamp" labeled disk but showed an "Apple_APFS Container disk1" as close to the correct size (250GB). /dev/disk1 shows "APFS Volume Bootcamp of 2.0MB. Running bootcamp gave me "The startup disk cannot be partitioned or restored to a single partition". Just wanted to reinstall Windows so I followed instructions found on macrumors (below).

diskutil eraseVolume jhfs+ BC1 disk0s3

diskutil eraseVolume jhfs+ BC2 disk0s4

diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s4

diskutil list

Afterwards bootcamp assistant ran so I tried to reinstall Windows 10. It went as far as trying to re-partition the disk but failed. Before and after diskutil list are attached. Any assistance would be appreciated as I have no idea what to do next. Thanks.

After:

iMac Pro

  • Step 1


In your specific case, given the current state, try


diskutil eraseVolume jhfs+ BC1 disk0s3

diskutil eraseVolume jhfs+ BC2 disk0s4

diskutil eraseVolume jhfs+ BC3 disk0s5

diskutil eraseVolume jhfs+ BC4 disk0s6


diskutil mergePartitions jhfs+ BCMP disk0s3 disk0s6

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.
