The first paste shows that your system was installed in UEFI mode.  If
your system was not in a state that would boot from UEFI (you mention
switching it from legacy to uefi after the boot failure), this could
explain the failure.

The boot-repair tool is not part of Ubuntu, so I can't account for any
changes it made to the system configuration when running.  What would be
useful for debugging is:

  - the output of 'efibootmgr -v' run from the installer immediately after finishing installation but before rebooting
  - the output of 'efibootmgr -v' run from the USB stick after a failed boot from the disk

Title:
  "No boot device found" on Dell E7250 laptop after clean install with
  encryption

Status in shim package in Ubuntu:
  Incomplete

Bug description:
  I just did a clean install of Ubuntu 14.04 LTS on a brand new dell
  Latitude E7250 laptop and it won't boot claiming "No boot device
  found".  I chose to completely overwrite the existing Windows 7
  installation and to encrypt the entire installation.  If I boot from
  the USB stick, I can see the three partitions created, the first 512MB
  with the boot flag, the second 244 MB listed as ext2, but this is
  presumably swap?? and the third is the crypt-luks partition that I can
  open up from the USB boot and see all the files no problem.  I suspect
  this is a BIOS boot configuration problem, but not sure how to
  diagnose.
