[Bug 1418706] Re: UEFI: blank drive incorrectly detected as existing BIOS-mode install

[vygotski]

For me, the error only occurred when I was installing from an empty ssd.
Formatting the ssd in gpt and creating one ext4 partition made the installer ask if I wanted to force UEFI ahead of the partitioning process. After that the installation works as usual.

Bug description:
  When doing a UEFI-mode install using the latest daily Vivid ISO (Thu
  Feb 5), Ubiquity incorrectly concludes that a blank drive contains an
  existing BIOS-mode install (see error in attached screenshot).

  The resulting error dialog is also broken: none of the buttons do any
  thing when clicked: X (close button), "Go Back", "Continue".

  You can seemingly move the install forward by clicking "Continue" in
  the main installer window, but things are still broken somewhere as
  grub isn't getting correctly installed (system is unbootable after the
  install completes).
