Hi Lukas, The system composed by Foreman (tftp) server and Power PC client is centos 7. I take the Foreman bootloader and move the grubppc64le.efi to the /var/lib/tftpboot/grub2 directory with the same result, from /var/log/messages:

Where this core.elf comes from? Can you try grubppc64le.efi from foreman-bootloaders package? We don't yet have debian packages, you can just unpack upstream tarball here: http://downloads.theforeman.org/foreman-bootloaders/ If that fails, try to build core.elf. yourself with grub2-mkimage: https://www.theforeman.org/2016/09/new-post.html LZ -- You received this message because you are subscribed to the Google Groups "Foreman users" group.
