To resolve this, you may go to the UEFI / BIOS and disable the Secure Boot option. This will resolve the messages coming up regarding drivers.


  • Secure Boot helps to make sure that your PC boots using only firmware that is trusted by the manufacturer. 
  • Disabling Secure Boot with BitLocker enabled may prevent your system from booting. It is recommended to disable BitLocker and ensure you have a working copy of your BitLocker recovery key. Right-clicking a BitLocker-protected drive and selecting Manage BitLocker will provide you the options to duplicate the recovery keys as needed.

  • After disabling Secure Boot and installing other software and hardware, it may be difficult to re-activate Secure Boot without restoring your PC to the factory state.
  • Be careful when changing BIOS settings. The BIOS menu is designed for advanced users, and it's possible to change a setting that could prevent your PC from starting correctly. Be sure to follow the manufacturer's instructions exactly.
