          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.

                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.

                    @busthead Do you see anything when typing dir FS0: at the shell? Also, can you upload the non-working ISO somewhere and send it to me via PM?

                    The Windows ISOs also require you to press a key to start Setup. If XCP-ng Center is not fast enough to display the screen then you may end up with the UEFI shell. Try starting the installation from Xen Orchestra or spamming a key when the VM is starting.

                      I found the other post I was thinking about. - https://xcp-ng.org/forum/topic/11333/windows-2025-standard-24h2.11-iso-release-of-sept-25-crash-on-reboot-with-inaccessible-boot-device-0x7b-in-xcp-8.2.1-and-xcp-8.3/15?_

                      That is issue both versions of the iso would boot but the newer one would have install issues.

                        Do you see anything when typing dir FS0: at the shell?

                        [13:17 xs1 ~]# dir FS0:
                        dir: cannot access FS0\:: No such file or directory

                        The Windows ISOs also require you to press a key to start Setup.

                        It appears I missed the key press to start setup 😵
