Title:
  grub-installer should fall back to grub-pc instead of grub-efi when
  there is no EFI system partition

Status in grub-installer package in Ubuntu:
  Fix Released
Status in grub-installer source package in Trusty:
  Fix Released

Bug description:
  During a side-by-side installation, the EFI partition is not created..
  If it doesn't already exist (which given recent bug reports seems to
  be the case on systems with MS Windows installed), installation fails
  at grub stage.

  TEST CASE:
  Note: This test case simulates in qemu the behavior found on real HW eg. bug 1299134

  1. Install trusty in BIOS mode

  $ qemu-img create -f qcow2 /tmp/disk.img 16G
  $ qemu-system-x86_64 -enable-kvm \
      -drive file=/tmp/disk.img,if=ide,media=disk \
      -pflash /tmp/bios.bin \
      -cdrom $ISO

  2. Reboot
  3. Reuse the same disk and Install trusty in UEFI mode for example start qemu with the option -pflash=/tmp/ovmf.bin and the binary file attached to this bug report.

  $ qemu-system-x86_64 -enable-kvm \
      -drive file=/tmp/disk.img,if=ide,media=disk \
      -pflash /tmp/bios.bin \
      -cdrom $ISO

  4. Proceed to the partitioner and select a side-by-side installation
  5. Proceed with the rest of the installation

  ACTUAL RESULT:
  This crash

  EXPECTED RESULT:
  There are several ways to address this issue, I see 2 options there are probably more:
  1.  Warn the user and refuse to proceed past the partitioner
  2. Create an EFI partition like the entire disk installation does.
