Hard drive is not detected
The reason why your hard drive is not detected is because your IDE cable is misplace, you need to open your computer unit so that you can adjust your cable just uninstalled it then reinstalled again. After that you need to check on BIOS setting to change the first boot of your computer, just choose the hard drive for first boot of the system,then save that settings when your done.
Try to restart your computer to see if the new settings is applied, your first boot should be your hard drive if still your hard drive is not recognize or your computer still didn't detect your hard drive, its time to replace your IDE cable with a new one because usually with this kind of problem it is always the cable that is become the source of the problem whether its your hard drive to your dvd -cd writer.
