The last line of your error message contains the solution:

"You'll need to use the recovery tools on your installation media. If you don't have any installation media (like a disk or USB device), contact your system administrator or PC manufacturer."

Translation: Start up from the disk that came with your laptop and follow repair tool instructions (or contact the manufacturer to obtain a copy - which you may possibly need to purchase. If you are not under warranty this will possibly be at a reduced cost.) Look for a label on the bottom of your pc for a phone number for service if your equipment is not useable. Good luck!
