If you want to install grub in GPT MBR, you will need BIOS boot partition. It better be located in the beginning to avoid any possible issues with BIOS access disk size limits.
here i do also not understand. actually i was thinking somewhere in mbr or gpt (the firts 2048 sectors) is the grub part which only says: "read /boot...."
Correct for MBR, wrong for GPT.
sorry still very unclear in my mind. so its not possible to boot from gpt-ext4 partition without having an additional uefi boot partition?
Not uefi boot partition, but a special, tiny partition, used by the bios to boot from the MBR on GPT disks. It is about 8 megabytes. -- Cheers / Saludos, Carlos E. R. (from Elesar, using openSUSE Leap 15.3)
