Morning, well i would say then that ur system is not setup to be in raid form, so this should sort it out for u.First thing you need to go into your bois and under intergrated, look for onboard serial ata/ide controler.Makesure that is set to either sata or ide which ever you use,your might find that it is set to either raid/sata or raid/ide and thats whats causing your problems.

Hope this helps let me know if not.

Thank you
