Title:
  Invalid BootEntry while reordering boot entries on some UEFI
  implementations

Status in curtin:
  Invalid
Status in subiquity:
  Fix Released

Bug description:
  On some UEFI implementations, it is acceptable for the UEFI
  BootCurrent variable to have no associated BootXXXX variable when
  booting from removable media (e.g., USB sticks).

  By default, after an install, curtin tries to set the install media as
  the default boot entry, i.e., BootOrder="$BootCurrent:$BootOrder"

  However, when BootCurrent does not have an associated BootXXXX entry,
  setting the boot order results in an exception:

  > Invalid BootOrder order entry value1004

  ^ where 1004 is the value of BootCurrent and Boot1004 does not exist.

  We got multiple reports of this bug on Dell XPS hardware, but also
  some other brands and models.

  For subiquity, it seems like an unwanted behavior to set the install
  media as the default boot entry, so disabling this behavior seems
  preferable.

  We should think about fixing the issue in curtin too.
