[Bug 956412] Re: Ubiquity placed grubx64.efi on USB disk

I don't think so, because the user did not know what EFI is.

Unfortunately i can't provide them, because the user reinstalled (after
disconnecting the USB key, and formating sda4,5,6,7), which led to the
situation described in Bug#959446 .

Title:
  Ubiquity placed grubx64.efi on USB disk

Status in “ubiquity” package in Ubuntu:
  Incomplete

Bug description:
  Computer with EFI boot

  Before installing Ubuntu:
  - sda with 3 primary partitions occupied by Windows
  - sdb (1Go USB disk)

  Here is the BootInfo after installing 11.10 :
  http://paste.ubuntu.com/884745

  As you can see, Ubiquity installed Ubuntu on the 4th primary partition
  (used as extended), but placed the /efi/ubuntu/grubx64.efi on sdb.

  Problem: when the USB key is disconnected, Ubuntu will not boot.

  If this behavior cannot be avoid (i guess /efi must be on the 1st
  primary partition of any disk), i suggest Ubiquity should at least
  warn the user that Ubuntu won't boot if the USB key is disconnected.

  Hope this helps.
