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

[Gastón]

Can confirm. Same UEFI error with hanged install due to unresponsive
dialogue window.

 - Ubuntu Gnome 17.04
 - Brand new blank SSD

I was able to complete the install with the workaround described in:

> https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1418706/comments/90
> I chose the first (default) installation option and let it create the partions. I aborted and rebooted when I had to select the timezone. Then I chose the manual partion mode and deleted all but the efi partion and created my partions

For the second (real) install I used:
 - encrypt
 - use lvm
 - something else

In my case this is the efi partition I got from the first (fake) install:
 - efi ~536 MB

I created two ext4 partitions for / and /home respectively; then
selected "encrypt home folder". Mentioning it for thoroughness.

At all times, during the default (fake) install and the manual (real) install I had:
 - Ethernet connected
 - check for upgrades
 - install 3rd party

---

To be able to boot I had to go once more into the BIOS and enable the
new UEFI SSD entry in the boot order list. That isn't related to the
bug. It is more specific to my motherboard and chosen security settings.
Still worth to mention.

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).
