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? Thanks. --
