Hi, 

would you mind sharing your whole config? I'm building SLES 15 SP7 UEFI Images for our company. And I don't have any issues. 

I'm using the boxbuild plugin though.

Regards

Sven

Hello Sven

This issue was solved here: https://groups.google.com/g/kiwi-images/c/TcSv-gd723A
The issue was the same for BIOS and UEFI boot.

Thanks for the reach-out.
