Thank you Longpanda for your fast response. 
Quote:press ctrl+i and then select the ISO file to boot.
This made the ISO boot successfully.
Didn't know about the Hotkey. Quote:Or you can try to directly boot the wim file with https://www.ventoy.net/en/plugin_wimboot.html
This was also successful.
Thanks for the hint. Quote:Can you share me such a wim file for test?
I will try to write a script for you to produce this kind of wim-file and ISO.
Do you have any Windows ISO? What filename?
I apologize for the delay. T.
