Fixed disk failure
Hard drive not setup properly in CMOS
Hard drive not detected
If you've recently installed any new hardware it's suggested that it be removed to verify it's not causing this issue. If after the device has been removed the computer works and it was another IDE/EIDE device ensure that the jumpers are properly set on the hard drive.
If you've recently moved the computer or installed anything inside the computer re-check the drive connections. Usually it's best to disconnect the cables from the back of the drive and reconnect them to make sure they're connected properly. While inside also disconnect and reconnect the cable connected to the motherboard as well. While inside your computer make sure you're aware of ESD.
Hard drive not setup
See if the hard drive is detected by fdisk. If the hard drive is detected but does not have a partition, create a new partition using fdisk. Additional information and help with fdisk can be found on our fdisk page.
If you have followed the above steps and you continue to experience the same issue, unfortunately it is likely that the hard drive is bad or the controller is bad.
If available, you may want to connect another known good hard drive to the computer to determine if it can be detected. If it is detected then replace your hard drive. If it is not detected, unfortunately you need to replace the motherboard or controller.
If no additional hard drive is available it is recommended that the hard drive be replaced first or that the computer be serviced or repaired.
