Boot disk failure no hard disk found - Computers & Internet

The error means that your system is not able to detect the hard drive on the system, check if the hard drive wire connections are tight and not loose and then try rebooting the system.

Look for hard drive stats on POST whether it succeeds or fails. This is how you can do that.
When system boots up, press the PAUSE?BREAK on the black screen and see whats system comment for your hard drive power test. If it succeeds and your hard drive's connections are also tight then possibly your hard drive might have crashed ( which means there are bad sectors on the hard disk).

Try performing disk checking on the hard drive to see if there are any bad sectors on the hard disk, the disk check will automatically fix the soft errors but if the errors and hard errors in that case the disk checking utility will not automatically fix the errors and you will need to get a new hard drive.

Thanks !!!
