I usually install Ubuntu first, using manual disk partitioning in the Ubuntu installer along the way to already create the necessary two partitions for LibreELEC. Then let the Ubuntu installation run free. Reboot the machine into Ubuntu, then copy the LE installation files to the LE system partition, add the GRUB menu entry for LE with the correct /dev/sdX numbers, update GRUB, and reboot. Et voila!

Klojum maybe copy/paste a sample GRUB menu file?

I can give my example, although it may not be "GPT proof". I still use the old method, I think.
