What you see
A white screen titled Surface UEFI, or, on older models, a black screen with configuration options like Trusted Platform Module and Secure Boot Control.
This is the Unified Extensible Firmware Interface screen (UEFI, formerly known as the BIOS). If you see this screen when you turn on your Surface, don’t make any configuration changes. Instead, try Solution 1.
Solution 1: Force restart
To find out how to force your Surface to shut down and restart, see Force a shut down and restart your Surface.
If Windows starts after you force a shut down and restart: Install the latest Surface and Windows updates to help prevent future problems. For more info, see Install Surface and Windows updates.
If Windows doesn’t start: Go to Solution 2.
Solution 2: Reset your Surface using a USB recovery drive
Start your Surface by using a USB recovery drive. Insert the USB recovery drive into the USB port on your Surface, and then press and hold the volume-down button while you press and release the power button. When the Surface logo appears, release the volume-down button. For more info, see Creating and using a USB recovery drive.
Still not working?
If these steps don't resolve the problem, you can submit a service order to Microsoft. Go to Device Service and Repair, register, and then select your Surface to start a service order.
