Details

Description:
EFI File Path Media Device Path is defined as NULL terminated string;
but chainloader built file paths without final NULL. This caused error
with Secure Boot and Linux Foundation PreLoader on Acer with InsydeH20 BIOS.
Apparently firmware failed verification with EFI_INVALID_PARAMETER which is
considered fatal error by PreLoader.
(copy-pasted from the git commit information)

Additional info:
* package version: latest grub and signed preloader.
* config and/or log files etc: nothing more, nothing less than usual.
* BIOS: InsydeH20, latest version for my laptop (Acer E1-570G)
* GRUB mailing list initial thread: http://lists.gnu.org/archive/html/help-grub/2016-12/msg00001.html
* git commit that should fix it: http://git.savannah.gnu.org/cgit/grub.git/commit/?id=ce95549cc54b5d6f494608a7c390dba3aab4fba7

Steps to reproduce:
* Install GRUB
* Set up PreLoader for GRUB as said in the ArchWiki
* Try to boot any EFI chainloader (in my case it was Windows)
This task depends upon
