ISO Build 26063 fails to boot in Hyper-V - but why?

yes, me too, the same. so i did a build 26058, and within a running instance,..
did a clean setup.exe from the 26063 build

 

Also on a host win server 26063 it gives the same error (it doesn't detect the keyboard orso)

 

Another alternative, is:
- use a copy vhdx of a working windows installation
- shift F2 safe boot
- repair, go to command prompt
- type 😧 (your build 26063 iso)
- run setup.exe

    The upgrade path does not seem to work in my case. I have to use the VHDX version I guess. Quite a bummer for "Use This Build For Bug Bash".

      they revamped the setup/install. if you run the setup as i described, you see a brand new setup action menu, i never have seen before.

       

      just install an older version ISO build first

      then,
      and after it (re)boots, press F2 / repair -> SAFE boot -> command prompt -> DRIVE 😧 
      type: SETUP.EXE

       

      what will work for sure

      I run now the newest WServer Build 26063 in Hyper-V. (and a nested one as well)

      works okey, but indeed won't boot when having the Windows_InsiderPreview_Server_vNext_en-us_26063.iso attached


      it looks it doesn't detect the keyboard quick enough
      it's pretty nice (but not working very good)
