[Bug 1796260] Re: UEFI install onto an MBR disk, with a pre-existing os/partition, results in a non-bootable ESP on a logical partition

[Dimitri John Ledkov]

well, maybe in bios mode we should install as gpt by default, on fresh
disks.

Such that "1. Boot in BIOS mode and install on entire disk" results in
GPT.

  UEFI install onto an MBR disk, with a pre-existing os/partition,
  results in a non-bootable ESP on a logical partition

Bug description:
  Ubuntu Cosmic Desktop 20181005

  Test Case:
  1. Boot in BIOS mode and install on entire disk
  => Verify that the system boots
  2. Boot in UEFI and perform a new installation alongside previous one
  => Verify that you can boot to the new system

  Actual result
  It fails immediately on boot with a message from the uefi firmware (its very brief because the system reboots immediately in a loop):

  """""
  System BootOrder not found. Initializing defaults.
  Creating boot entry "Boot0011" with label "Ubuntu" for file "\EFI\ubuntu\shimx64.efi"

  Reset System
  """""

  The BIOS installation boots fine if I switch back to BIOS mode.
  An UEFI installation on entire disk boots fine.

  Log files of the UEFI installation attached.

  The EFI partition is created and its content is:
  .
  ./EFI
  ./EFI/ubuntu
  ./EFI/ubuntu/grubx64.efi
  ./EFI/ubuntu/shimx64.efi
  ./EFI/ubuntu/mmx64.efi
  ./EFI/ubuntu/BOOTX64.CSV
  ./EFI/ubuntu/grub.cfg
  ./EFI/BOOT
  ./EFI/BOOT/BOOTX64.EFI
  ./EFI/BOOT/fbx64.efi
