Go to https://support.microsoft.com/en-us/surfacerecoveryimage (if you enter

To reset your Surface from a USB recovery drive:

Step 2: Insert the USB recovery drive into the USB port on your Surface.
Step 3: Press and hold the volume-down button while you press and release the
power button on your Surface.
Step 4: When the Surface logo appears, release the volume button.
Step 5: When prompted, select the language and keyboard layout you want.
Step 6: Select Troubleshoot > Reset your PC.
If prompted for a recovery key, select Skip this drive at the bottom of
the screen.
Step 7: Select the target operating system you wish to reset. This
refers to the current operating system installed on your Surface.
Step 8: Select Yes, repartition the drives, and on the next page, select Next.
Step 9: Choose Just remove my files.
Step 10: Select Reset.
Surface restarts and the Surface logo displays while the reset process
continues (this can take a while).
If it does not work in the UEFI, it is very unlikely imaging will fix this.
