‘Surface 2 Pro’ is now displayed as white characters on a small black background with the rest of the screen a bright red. How do I fix this?
If you reinstall Secure Boot keys it will fix the issue:
- With the Surface powered off, press and hold the Volume Up button.
- Power on the Surface , holding the Volume Up button pressed the entire time.
- Once the Surface enters into the UEFI interface, select “Install Default Secure Boot Keys” and select “Yes” to cause the Surface to load the default secure variables.
- Make sure that the “Secure Boot” option is enabled, exit setup, choosing “Yes” to save the configuration changes.
