[Bug 1267829] Re: Ubiquity installs EFI related stuff in non-EFI system (Ubuntu does not boot after install)

[Sergio Benjamim]

Yeah, it seems that it booted as UEFI (i can confirm by grub window in
the install usb). But windows is installed as non-efi, there is no EFI
partition in this disk, as we can see in the picture. So, it seems UEFI
is disabled. There is no option to disable it in BIOS.

Is it possible to change this option in ubuntu media installation?

Title:
  Ubiquity installs EFI related stuff in non-EFI system (Ubuntu does not
  boot after install)

Status in “ubiquity” package in Ubuntu:
  Invalid

Bug description:
  I installed 2 times xubuntu trusty in a machine with UEFI disabled,
  windows 7 dual boot in a MBR disk, and in the 2 times it does not
  install grub correctly. In the firt time, it goes direct to windows 7
  boot. In the second time, i got an error, like this:

  error: file '/boot/grub/i386-pc/normal.mod' not found.
  Entering rescue mode...
  grub rescue>

  I used Boot Repair, and i had to run some commands in terminal:

  sudo chroot "/mnt/boot-sav/sda5" dpkg --configure -a
  sudo chroot "/mnt/boot-sav/sda5" apt-get install -fy
  sudo chroot "/mnt/boot-sav/sda5" apt-get purge -y --force-yes grub* shim-signed linux-signed*
  [...]
  The following packages will be REMOVED:
    grub-common* grub-efi-amd64* grub-efi-amd64-bin* grub-efi-amd64-signed*
    grub2-common* linux-signed-generic* linux-signed-image-3.13.0-1-generic*
    linux-signed-image-generic* shim-signed*

  sudo chroot "/mnt/boot-sav/sda5" apt-get install -y --force-yes grub-pc linux
  [...]
  The following extra packages will be installed:
    grub-common grub-gfxpayload-lists grub-pc-bin grub2-common

  The complete stuff in terminal was attached bellow. See
  http://paste.ubuntu.com/6725509/ too.

  And now it is bootable.

  So... why there was installed grub-efi and linux-signed, if this
  machine has EFI disabled? I don't sure if it is related to the
  problem. But i can reproduce this problem.
