While I can't find any specific reference to your problem, you are running the oldest possible version of 10.3.2, which had 13 Maintenance updates released for it, so I'd certainly recommend upgrading as a first step.
It's worth noting as well, that while the article you linked specifically references UEFI enabled machines, the version of SED you're running doesn't support UEFI.
