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

[Caitlyn Martin]

OK, I've worked around the problem.  First, I can confirm what vygotski
reported:  it only happens if you are installing to a blank SSD.  I
created my ESP (FAT32) partition first and made it larger (300 MB) and
the rest of my custom install worked after that.  Not a huge problem but
it would be nice if it was at least documented somewhere.

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).
