The Win10 system of the Surface tablet turns red when the system is installed. Only the middle Surface is white on a black background, and the rest is red. What is going on here? What should I do at this time?

This problem occurs because the user has changed the default settings of UEFI. In this case, you only need to restore these settings back to the default to restore the original black background white screen.

The specific method is as follows:

The method is applicable to all Surface devices of Microsoft.

1. Press the power and volume plus button at the same time, and wait for the Surface logo to appear on the screen to release the UEFI setting interface;
