@busthead 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.

Keep us posted, happy to hear from it!

Hello All, This issue seem to completely go away on a older branch/tag if i build it from below for XO: xo-lite-v0.17.0 So the issue I would think is coming from the newer version of XO. Not sure best way to test this. So I am going back to an older commit. If anyone has any suggestion I can try helping as its an annoying issue.
