[Bug 1111950] Re: Ubiquity should be able to install both grub-pc and grub-efi when needed

[Jerome Haltom]

I strongly agree with this.  There's not any good reason I can come up
with (other than history) for grub-efi-* to conflict with grub-pc.

A single grub-install invocation should attempt to install both. If
theres a EFI system partition, the EFI install succeeds. If there's a
BIOS Boot Partiton or MBR, grub-pc succeeds. However you want to boot
gets booted, with the firmware likely preferring EFI.

Title:
  Ubiquity should be able to install both grub-pc and grub-efi when
  needed

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  In some situations, it would be useful if Ubiquity (the Ubuntu
  installer) could install both grub-pc and grub-efi at the same time:

  1) when the Ubuntu live disk is launched in Legacy mode, but there is
  an ESP on the disk.  (it can happen that the firmware is setup to boot
  the HDD in UEFI mode, but the live media in Legacy mode).

  2) when the Ubuntu live disk is launched in UEFI mode, but there is
  another OS (eg Windows installed in Legacy mode) with no ESP on the
  disk.  (it can happen that the firmware is setup to boot the HDD in
  Legacy mode, but the live media in UEFI mode).

  Remarks:
  - from a live disk, it is impossible (AFAIK) to know in which mode the firmware is setup to boot the HDD.
  - of course, prior to perform this improvement of Ubiquity, we need to improve GRUB2 to allow grub-pc and grub-efi to be installed at the same time.
