If this is the OS drive then make sure it's connected to the Intel controlled sata port and it's the port 0.
Well, Where the SATA 0 and 1 are on the MOBO, theres no places to insert the SATA, just a white lego-like piece? It says SATA 0 and SATA 1 next to it, like it does where 2 3 4 5 are, but instead of spots to plugin the SATA cords, its a White lego-like piece. Help please! Thanks lots!
