@george1421 OK I see, and thanks for that!
I went through the dirty bit and realised Sysprep was the issue in hand, as it was re-imaging over the same sysprepped image which seems to cause issues with cloning.
Removing the bit didn’t seem to work, so I then had to completely re-install a fresh Windows and start over again, and ran sysprep and fog cloned it successfully.
I see why using VM would be easier as you can sysprep as many as you need etc.
Thanks!
