OK so I actually found out how to do the above thing. So apply the provided patch for /etc/grub.d/00_header. Original used for patching is from Ubuntu 17.10 (GRUB 2.02~beta3-4ubuntu7.3). Move or create your grub env block file to efi partition: ubuntu original location: /boot/grub/grubenv patch location: /boot/efi/EFI/ubuntu/grubenv Run update-grub2 to create the new grub config.
I do not know what EFI specs or something like that says abount using EFI partition for the GRUB env block, but it DOES work for me. ** Patch added: "Patch for /etc/grub.d/00_header" https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/736743/+attachment/5134475/+files/grub_env_block_on_EFI.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/736743 Title: environment block not implemented on btrfs To manage notifications about this bug go to: https://bugs.launchpad.net/grub/+bug/736743/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
