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

[Fred Palmer]

It is my understanding that ESP is the correct full Initials (name) for
what we often just call the efi partition.

 EFI System Partition (ESP)
Ubuntu installers have referred to the ESP by the name "EFI boot partition,"

But use of boot partition has confused new users thinking that is
Ubuntu's boot partition or they need another /boot partition or do not
need a /boot partition when they may need one.

Title:
  Vivid: UEFI: blank drive incorrectly detected as existing BIOS-mode
  install

Status in partman-efi package in Ubuntu:
  Invalid
Status in ubiquity package in Ubuntu:
  Triaged

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).
