How to reset your Surface using your USB recovery drive:
Important:
A reset returns your Surface to its factory settings. It deletes all of your personal files, resets your settings, and removes all apps that you installed.
Note:
Make sure you have access to the product keys and installation files for any desktop apps, such as Microsoft Office, that you plan to reinstall after the reset.
1.Make sure your Surface is turned off and plugged in, and then insert the USB recovery drive into the USB port.
2.Press and hold the volume-down button while you press and release the power button.
3.When the Surface logo appears, release the volume button.
4.When prompted, select the language and keyboard layout you want.
5.Select Troubleshoot > Recover from a drive. If prompted for a recovery key, select Skip this drive at the bottom of the screen.
6.Select the target operating system you need to reset. (This refers to the current operating system installed on your Surface.)
7.Choose either Just remove my files or Fully clean the drive.
The option to clean the drive is more secure but takes much longer. For example, if you’re recycling your Surface, you should clean the drive. If you’re keeping your Surface, you just need to remove your files.
8.Select Recover.
Surface restarts and displays the Surface logo while the reset process continues. This can take several minutes.
