[Bug 1087653] Re: grub2-signed doesn't support removable drive.

[Launchpad Bug Tracker]

This bug was fixed in the package grub2 - 2.00-7ubuntu14

---------------
grub2 (2.00-7ubuntu14) raring; urgency=low

  * When installing to removable media with UEFI Secure Boot, install
    gcdx64.efi.signed rather than grubx64.efi.signed (LP: #1087653).
  * Make gcdx64.efi.signed fall back to sourcing $prefix/grub.cfg if
    $prefix/x86_64-efi/grub.cfg is missing, as is likely when using
    'grub-install --removable'.
