Hi, i uploaded a new development snapshot of GNU xorriso which can create a GPT similar to the result of Lucap's gnome disks run.
cd "$HOME"/xorriso_dir wget http://www.gnu.org/software/xorriso/xorriso-1.5.5.tar.gz tar xzf xorriso-1.5.5.tar.gz cd xorriso-1.5.5 ./configure --prefix=/usr make Then xorriso/xorriso -version should say GNU xorriso 1.5.5 : RockRidge filesystem manipulator, libburnia project. ... Version timestamp : 2021.05.25.195904 ... This program is able to repack "$ORIG" to gnome disks' idea of a GPT: "$HOME"/xorriso_dir/xorriso-1.5.5/xorriso/xorriso \ -indev "$ORIG" \ -outdev "$NEW" \ -changes_pending yes \ -boot_image any replay \ -boot_image any mbr_force_bootable=off \ -boot_image any gpt_iso_bootable=on \ -boot_image any gpt_iso_not_ro=on Inspection of "$NEW" by xorriso should yield ... MBR partition table: N Status Type Start Blocks MBR partition : 1 0x00 0xee 1 5503775 GPT : N Info ... GPT partition flags: 1 0x0000000000000005 ... The partition tables of "$NEW" will differ from "$ORIG" by: - No dummy MBR partition 2, because of mbr_force_bootable=off. - bit 2 = "Legacy bootable" of the ISO 9660 partition is set, because of gpt_iso_bootable=on - bit 60 = "Read-only" of that partition is not set, because of gpt_iso_not_ro=on (The latter two -boot_image options are new in 1.5.5.)
