Just built my first PC and am trying to install windows 7, but no drives are detected to install it on. I have the Seagate Momentus XT hard drive and the thermaltake level 10 super GT case. I have connected the HDD bays to power and the SATA is plugged in, but my HDD still is not recognized no matter what I do, I boot up, with the ASrock Extreme 3, click F2 to go in my UEFI setup utility and am trying everything I know, but my HDD just is not showing up. Someone said I may need to setup it up before hand, but I dont know what that means. Any advice is appreciated, ill try anything. I have become so frustrated and dont have a clue what im doing wrong.
