I found the wiki page you were referring to [1] and followed the mentioned advise, that is, I created the ext4 filesystem without the '64bit' feature. It worked! Booting is possible now.

Unfortunately I did not find that wiki page when I was conducting my own research. There were some locations were I suspected this kind of information (namely the "Common Problems" [2] and the "EXTLINUX" page [3]) but couldn't find any.

Thank you for your help!

Best regards
