[Bug 1015211] Re: Ubiquity installed grub-efi when it should have installed grub-pc

[martinr]

I verified in the intial install logs (/var/install/syslog) that
erroneously grub-efi was installed instead of grub-pc:

Title:
  Ubiquity installed grub-efi when it should have installed grub-pc

Status in “ubiquity” package in Ubuntu:
  Incomplete

Bug description:
  Goal:
  Create a dual boot system with a pre installed Win7x64 and Ubuntu Desktop 12.04 LTS amd64 with Grub installed as the boot-loader in the MBR of sda.

  Problem symptoms:
  After Ubuntu installation from the Live CD along side Win7x64, Grub wont start at boot-up of the system. It boots straight into Win7.

  Hypothesis:
  The Ubuntu Desktop 12.04 amd64 Live CD, was booted with an UEFI boot sequence although the hard disk structure is MSDOS with MBR. This fools ubuquity into installing Grub in EFI mode and does not install grub-pc into the MBR.
