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

[Ákos Laczkó]

I've experienced this problem as well on Ubuntu MATE 16.04.2 LTS, but
managed to resolve it.

This issue seems to be related somehow to the existing partition table
of the drive: even after manually creating a new GPT table in gparted
(or KDE partition manager) I got stuck at this message, but if I created
a new partition table for the blank drive inside "something else" the
message did not show up (dispite the fact that it also creates a GPT
table if I'm correct). I assume that's why the default install method
worked for everybody here - this step must be included in that one as
well.

Reproduced this three times (error and resolution as well). Hope this
helps somehow to the devs.

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).
