The notebook cannot detect the hard disk when you turn on the notebook.
First - re-seat the harddisk and reboot the computer. If the computer does not boot up then reboot andgo into the BIOS configuration to see if the BIOS detects the hard drive. If itdoesn't detect the hard drive then it could be faulty. Next - to check if the harddrive is faulty, remove the hard drive and insert it into an USB hard drive adapter and connect it to a workingcomputer's USB port. If this computer cannot see itas an external hard drive and you cannot open the various folders and files,this confirms the hard drive is faulty. Then the hard drive needsto be replaced in the computer/laptop, Windows installed and the computer orlaptop's device drivers plus your programs etc. to get a functioningcomputer/laptop again.
