Most likely your hard drive has crashed. I repaired several laptops with that error and I had to replace a HD and reinstall operating system. Some laptop manufactures will provide a system recovery disk which will help you to reinstall your operating system. Otherwise you will need to install it from scratch. Most likely all your data is lost.
