[Bug 1013595] Re: grub-efi does not boot

[YannUbuntu]

Here Ubiquity (the Ubuntu installer) incorrectly installed Ubuntu in EFI
mode when it should have installed in in Legacy mode.

Probably because the BIOS is setup to boot the liveCD in EFI mode, but
is also setup to boot the HDD in Legacy mode.

@Robert: please could you indicate if you installed Ubuntu alone, or in dualboot with Windows ? 
please could you also indicate your Boot-Info URL ( https://help.ubuntu.com/community/Boot-Info ) ?

Title:
  grub-efi does not boot

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  A standard installation of ubuntu-desktop on a HP Compaq 6200 PC
  installs grub-efi and is not able to boot after first restart.

  Grub complains about "no such partition". It is not able to load its
  own modules to continue with the boot process.

  After booting into a rescue system and manually replacing the grub-efi
  package with grub-pc and re-installing grub to the MBR the computer
  boots fine.

  Why is grub-efi installed automatically?
