IIUC "proper partition setup" for callers of curtin is:
/boot/EFI partition *and* a grub_bios partition. Something like: config: - id: main_disk type: disk ptable: gpt serial: disk-a name: main_disk wipe: superblock grub_device: true - id: bios_boot type: partition size: 1MB number: 1 - device: main_disk flag: boot id: main_disk_part2 number: 2 size: 512M type: partition wipe: superblock The curtin part would be to ensure that shim-signed *and* grub-pc packages are installed into target. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827929 Title: curtin should support making installed systems BIOS+UEFI hybrid bootable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/curtin/+bug/1827929/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
