[Bug 953959] Re: Ubiquity fails to install Grub in Precise

Yesterday, I repeated a fresh install with the daily build of yesterday.
The problem is still there: Ubiquity installs Ubuntu fine, and installs
Grub as well. Only... it wrongly identifies the BIOS as EFI, so it
installs the Grub EFI packages.

Which makes the laptop unbootable, because it's an ordinary BIOS and no EFI at all. Repair is easy: boot from the LiveCD and install the ordinary Grub by hand.
sudo mount /dev/sda7 /mnt
sudo grub-install --root-directory=/mnt /dev/sda

Then there's no problem anymore: Ubuntu boots fine and all is well with
the world.... :-)

Is there any chance of the erroneous EFI detection being fixed?

Title:
  Ubiquity fails to install Grub in Precise

Status in “ubiquity” package in Ubuntu:
  Incomplete

Bug description:
  On my Lenovo B570e laptop with EFI BIOS, Ubiquity fails to install
  Grub. With the LiveUSB of Precise Pangolin 12.04, amd64, daily live of
  March, 12.

  However, when I *manually* install Grub from the terminal in the live
  session of Desktop CD, it does install fine. Then I can boot into
  Precise from the hard disk after all. This happens both in Ubuntu,
  Xubuntu and Lubuntu 12.04.

  I have attached both /var/log/syslog from the LiveUSB-session and a
  hardware list (output of lshw).
