If you have a problem starting Windows, you can use one of several startup options to help you start Windows in a safe environment where you can restore settings and fix the problem. Safe Mode is a good place to start. If a problem does not occur when you start in Safe Mode, you can eliminate basic Windows files and drivers as possible causes of the problem. If you added a device or changed driver, you can use Safe Mode to remove the device or restore the changed driver. You can also use Choosing Last Known Good Configuration to restore settings saved when your computer was last shut down properly.
Start Windows When Problems Occur
Restart your computer.
As your computer boots, press and hold F8.
Use the arrow keys to select a startup option, and then press Enter.
If you have a dual-boot system, select the operating system you want, and then press Enter.
Restore any recent system changes, or remove any newly installed software that might be causing the problem.
Shutdown your computer.
Start your computer to see if it works properly.
If problems persist, try a different startup option, or seek assistance from a support technician.
