I recently built a pc a little bit ago and when I installed the hdd correctly(power and sata firm) in the first sata slot of the mobo, it kept saying it could not find any device, even though in the BIOS it says there is a hard disk in the first sata slot. Also, in the boot tab it says the device is disabled. The hdd already has bootable data on it(w7) and I tested it on another computer and it works fine. I also tested it on the the other sata connectors on the mobo. What should I do?!
