Please advise.

@busthead Try turning off Secure Boot.

Changed to UEFI Boot but same result:

@busthead

What version win 25h2 are you using? Mine is from 10/4/2025 and boots just fine.

I suspect the issue is that I'm using XCP-ng Center rather that Xen Orchestra. Is there a xe or xo-cli command I can execute that list my Win11x64 VM config details so we can compare?

I am not sure. I just downloaded this version - 26200.6584.250915-1905.25h2_ge_release_svc_refresh_CLIENT_CONSUMER_x64FRE_en-us and no boot issues. There was a discussion on this forum about similar issues. The every first iso for 25hX (not sure 1 or 2) that would boot. The new version would not. My Iso was from around then. But i renamed it so i dont know the exact version. When trying to download the lates iso from micrsoft.com/download the page errors out before letting me download the iso.

@acebmxer

Given both are the same size, I don't believe the ISO is the issue. It's likely XCP-ng center or some other issue with my XCP-ng setup.
