I understand completely, but I have to make a choice between the SSD's
performance and my graphics card, and in this particular instance, I
would rather loose the SSD's performance rather than not being able to
use my NVIDIA.

Thank you for the pointer, it would never have occurred to me that
this would be possible. I was already looking for good ram deals.

Totally agreed. The whole UEFI implementation anyway feels like a
hastily patched together thing, if not on paper, at least in its
current implementation (afaic). While we get somewhere stable, we
should have some sort of knowledge base for people like me, noobs or
semi-techies, who need to understand how to boot their OS.

but I can't manage nor build a community (I just know no one
knowledgeable, and I am not knowledgeable myself). If anyone's
