The system is not recognizing your harddrive at all. If you have another, try putting that one in the system.
Or you could take it into a repair shop.. But again… the errors you are getting are because the computer
does not see any harddrive hooked up to it.
It depends upon what type of ‘systems failure’ you had and how often it occurs as to what you do (if anything). You are being too vague for us to know exactly why/how the fault occurred or what it said caused the failure.
System failure error shows some serious problem in your hardware, check if all devices are properly attached or some may be loosen, if you cannot configure acctual problem then take it to some professional
