Thanks, but as said, upgrade isn't proposed (greyed out), only clean install (when using a fresh 20H2 image and running setup.exe.
Reasons:
- you try to install windows in an non standard location (mine is c:\windows) very uncommon indeed (sarcastic)
- you try to install an older version. (my Windows is 20H2 and I just downloaded a fresh 20H2 ISO image for the install)
If using the image creation tool, then it states that it does not support this version (enterprise).
I'm stuck at this point...
