Red boot screen on Microsoft Surface Pro

Surface Pro 2 Red Boot Screen

If your Microsoft Surface Pro 2 starts has a red boot screen instead of the normal black then you may have disabled the UEFI (Secure Boot) function in the BIOS. If you enter the BIOS as detailed hereĀ BIOS, then re-enable the Secure Boot option and reinstall the Secure Boot Keys. The screen should then be back to normal.
