   • Immediately press and hold the Shift key.
     
   • Keep holding the Shift key until you see the Choose an option screen.
     
3. Click on Troubleshoot.
   
4. Click on Advanced options.
   
5. Click on Start-up Settings.
   
6. Click on the Restart button.
   
7. When your computer restarts, you will see a list of options. Press the 4 key to select Safe Mode with Networking.

   • Click on the Start button.
