Fail to download

[dadoxd_]

Hello
I am trying to install opnsense, but can't get it to work.
The pc I am trying to install it in are a Fujitsu S920, with swapped msata and ram.
I am getting Write FPDMA Queued during install and after the install its says GPT Boot partition write failed.
Does anyone know what to do about it? I have tried install both img and iso.
