I did it !!
So I basically made a Frankenstein’s monster version of my image.
As I’ve stated in my last comment, I had an issue where the windows drive did not have the same partition number.
I created a new legacy windows 10 VM, with a smaller C Drive than I created the very first time I worked on that image. I converted that installation into UEFI.
So now my newly installed win10 and my oversized image have the exact same disk structure.
I deployed the partition containing all my data onto the new VM, and I had an issue where the UEFI boot was broken.
I used the tools in the installation media to repair the EFI partition. I used diskpart to assign a letter to the EFI partition, exited diskpart and ran this command :
bcdboot C:\Windows fr-fr /s B: /f
Now I’m capturing the image and I’ll deploy it to make sure it’s working fine
Thanks for all the help and ideas!!
