Start computer and Press Del to Boot into Setup (Bios) go to Integrated Peripherals, or Advanced tab. Look for SATA controllers. If you only have one drive attached (ie) plugged into SATA port 1 on the motherboard, and you get the message Can't find any device, then using your arrow and Enter keys, Disable any SATA controller that are not being used. If you are trying to use the Secondary drive, make sure the SATA controller/port that the drives data cable is plugged into is Enabled in the Bios, Save and Exit, then boot back to the Bios to see that the HDD is listed there in the Main window.
