Title:
  Ubiquity copies efi boot information to wrong ESP

Status in ubiquity package in Ubuntu:
  Confirmed

Bug description:
  I'm installing Ubuntu 16.04 onto an external HDD. My computer also has
  an internal Windows 10 HDD.

  When at the partitioning stage, it selected for the boot loader to be
  installed onto the external HDD.

  When Uniquity is installing the system, it mounts Windows 10's ESP and
  copies the Ubuntu/grub boot loaders over, when it should have mounted
  the ESP created on the external HDD. I attached a screenshot of lsblk
  to show what's happening. /dev/sda2 is the Win10 ESP and it's mounted
  to /target/boot/efi. /dev/sdb1 is the correct ESP but is not touched.

  Because the boot information is not on the external HDD, the Windows
  10 disk must be present to boot Ubuntu because the boot information
  pointing to Ubuntu is located on the Windows ESP.

  Ubiquity is version 2.21.63.

  I also attached the Ubiquity debug file, partman, and syslog. Sorry
  for putting them in a zip, can't attach more than 1 file.
