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

[Colin Watson]

Did the EFI System Partition on /dev/sdb1 exist before the install?  If
not, it must have been created using manual partitioning, which is odd
if it wasn't intended to be used.

Installer logs (syslog and partman) would help.

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.
