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.
If you know how to open your computer CPU, try unplugging everything your hard drive. In short, make sure they are properly connected. If not, then you need to bring it to a shop.
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
