    Windows 8 with Secure Boot enabled may no longer boot after installing new hardware

    Symptoms

    Consider the following scenario:

    •You have a certified Windows 8 or Windows RT UEFI-based computer and Secure Boot has been enabled in the computer's BIOS.
    •You make changes to the computer's hardware. Examples would include adding a new graphics, networking or storage controller adapter.

    In this scenario, Windows may no longer boot after the changes are made. You may encounter behaviors such as hanging at a black screen, Windows crashing with a blue screen, or BIOS error messages to change your settings.



    Cause

    This behavior may occur when Secure Boot has been enabled in your computer's BIOS. Secure Boot protects the integrity of the operating system and prevents unauthorized firmware, operating systems or UEFI drivers from interfering with the boot process.

    Resolution

    To work around this issue, Secure Boot must first be disabled before installing new hardware. For more information on disabling Secure Boot in your computer's BIOS, reference the manual that came with your motherboard or contact your motherboard manufacturer. If you are in an enterprise environment, contact your system administrator.
