Hi @george1421, @Sebastian-Roth, @Tom-Elliott
For information, the root cause of the problem seems to be the original partitioning from DELL.
I’ve based my master image on the pre-installed “out of box” Windows 10. Not a good idea…
So i have done a clean install of Windows 10 from a Microsoft ISO, partitioned the disk in two volumes (plus the recovery partition and EFI boot partition automatically created) so we have a and D:, and done again the image process and it worked like a charm!
Thanks team!
