I have a Dell model PP01L laptop which is been installed with Windows Vista. The problem is that I am not able to work well or get the thing to be processed. When I start the system I got an error message as Windows is shutting down to prevent damage to windows. After that when I rebooted it said no hard drive found and asked to insert disk. Please help me out so that I can make the changes to be worked and process as needed. It will be better.
