The Advanced Boot Options menu lets you start Windows in advanced troubleshooting modes. You can access the menu by turning on your computer and pressing the F8 key before Windows starts.
Some options, such as safe mode, start Windows in a limited state, where only the bare essentials are started. If a problem does not reappear when you start in safe mode, you can eliminate the default settings and basic device drivers as possible causes. Other options start Windows with advanced features intended for use by system administrators and IT professionals. For more information, go to the Microsoft website for IT professionals.
