Follow-up Comment #2, bug #61364 (project grub): I solved the problem using grub 2.11 directly from https://git.launchpad.net/grub and building on ubuntu 20.04 the grubnetx64.efi using the following script:
apt-get update apt-get build-dep grub2 -y git clone https://git.launchpad.net/grub cd grub git checkout 246d69b7ea619fc1e77dcc5960e37aea45a9808c ./bootstrap ./configure --with-platform=efi make cat >"grub-netboot.cfg" <<EOF if [ -e \$prefix/$platform/grub.cfg ]; then source \$prefix/$platform/grub.cfg elif [ -e \$prefix/grub.cfg-$deb_arch ]; then source \$prefix/grub.cfg-default-$deb_arch else source \$prefix/grub.cfg fi EOF mkfs.msdos -C "memdisk-netboot.fat" 64 mcopy -D overwrite -i "memdisk-netboot.fat" "grub-netboot.cfg" ::grub.cfg CD_MODULES="all_video boot btrfs cat chain configfile echo efifwsetup efinet ext2 fat font gettext gfxmenu gfxterm gfxterm_background gzio halt help hfsplus iso9660 jpeg keystatus loadenv loopback linux ls lsefi lsefimmap lsefisystab lssal memdisk minicmd normal ntfs part_apple part_msdos part_gpt password_pbkdf2 png reboot regexp search search_fs_uuid search_fs_file search_label sleep smbios squash4 test true video xfs zfs zfscrypt zfsinfo" CD_MODULES="$CD_MODULES cpuid play" CD_MODULES="$CD_MODULES tpm" NET_MODULES="$CD_MODULES http tftp" ./grub-mkimage -O x86_64-efi -o grubnetx64.efi -d grub-core -c grub-netboot.cfg -p /grub $NET_MODULES # generated grubnetx64.efi _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?61364> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
