[11:35] I'm trying to ask kep question, not sure where best to ask [11:36] I'd like to add uefi boot capability to a system upgraded from 20.04 to 22.04 ... now have a /boot/efi partition of type 0xEF (EFI system partition). [11:36] installed grub-efi-amd64-bin and grub-efi-amd64-signed ... grub-install /dev/sda doesn't help, presumably legacy installer ... [11:37] I thought, new 22.04 installs now always support both legacy and uefi booting ,and use GPT regardless on new disk partitioning but for-certain the GPT isn't actually required. MBR will work fine too, this is how classic multi-bootable-disks hava always worked, etc. [11:38] I'd like to know how the ubiquity actually does set up this legacy and uefi combo in a way that works with the packafing sysem, which wasn't traditionally set-up to have grub-pcand grub-efi-amd64 at same time. [11:41] p.s. the /boot/efi fat is correctly in /etc/fstab [14:10] aha [14:10] 11:57 < gjolly> enyc: have you tried something like grub-install --boot-directory=/boot --efi-directory=/boot/efi --target=x86_64-efi (assuming you are on x86_64)?
