Ok, problem solved. You're right, the BIOS option was wrong.
The problem is that it's called "RAID mode" and I found it not
intuitive since I don't use RAID (so I didn't touch it). I changed it
from IDE to AHCI and it worked.
So just a quick and last question. I read here the following:
http://forum-en.msi.com/index.php?topic=106575.120
"AHCI is a native SATA Mode. There is not necessarely a major
performance difference between IDE/Legacy Mode and AHCI Mode".
Of course this guy is talking about Windows, but can it be
applied to Linux too? I mean, does AHCI offers no significant
performance improvement over SFF/Legacy mode?
Depends on a lot of things, and what you mean by "significant". You
don't get NCQ in legacy mode, and you also don't get 64-bit DMA support,
which gets more significant the more RAM you have.
