Hyper-v hang at first boot

[ante1377]

Hyper-V hangs after trying to do first bootup.

using iso: Win11_25H2_EnglishInternational_x64.iso

after some troubleshooting tried iso: Win11_24H2_EnglishInternational_x64.iso and it boots up fine.

Dosent work for me sadly - can anyone else say if they have the issue when they try this fix too?

22H2 works for me (but doesn't upgrade to 25H2 via updates, it's stuck on 22H2), I have to find the 24H2 ISO to try it out. Hopefully today.

EDIT: managed to install 24H2 which then updated to 25H2 and it boots normally.
Has anyone tried to make a VM with the same process as this script uses but without any modifications (drivers, GPU-PV, Sunshine, etc.)?

I initially had the same problem with 25H2, until I found out you have to enable and use Enhanced Session Mode Policy, and connect to the Windows VM using the Hyper-V manager for the first time. After that everything works as expected, at least for me.
