Hi,
I've been trying to create an updated .WIM for Windows 10 2019 LTSC. I've succesfully built the custom .WIM in the Build Lab deployment share, but when I try to deploy it in a standard task sequence, I have problems. When it restarts at what I think is the last step in the Postinstall phase, it will never boot back up. It will remain in this state, with the black Hyper-V logo and spinning dots, indefinitely. Here's what I've done to try to resolve it:
Updated the deployment share and boot images
Built new reference images
Built all "OOB" reference images and task sequences (no added applications and no customization of the reference image or task)
The non-LTSC reference image and task sequence work from these same deployment shares beautifully
Tried both in Gen 1 and Gen 2 VMs
Here is the last bit of log on one of these attempts. Since the machine never boots back up, I had to mount this virtual disk on another VM to pull out the BDD.log. Event 41017 is the last entry.
