Igor, I rejected your message for the list as the screenshot was far too large a file - there's no need for >1MB screenshots, just resize it to a smaller size before attaching.
openQA already caught that bug and I filed it:
https://bugzilla.redhat.com/show_bug.cgi?id=1624532
it is specific to x86_64 UEFI, at least in openQA testing, boot works OK on BIOS.
