WinPE 10 Driver Blocked (signature could not be verified)

    Question

  • I just updated a Driver in my WinPE boot image, now when i try to boot to that WinPE boot image i get the following error. Can anyone explain why this is happening. by the way, this only happens with secure boot enabled. I really don't want to have to disable secure boot. this only started after the driver update. The actual error is on the black image at the bottom. i added a screenshot of the cert info too.

  • Oh, and my WinPE Boot Image is 10.0.10240. i don't think updating it would help this, if anything i would assume that newer versions would be more strict.

  • For secure boot to work, I believe the driver has to be signed by Microsoft to work with Secure boot. You might want to check back with the vendor.

    You might want to move up to the latest WinPE build.

  • Hi Jaybird283,

    According to your description, firstly, we could try to download Windows 10 ADK to update the version to check.

    As you said, if it isn’t related to the issue. I suppose that the certificate couldn’t be validated by Microsoft. It couldn’t pass the Secure Boot.

    For the picture you provided, it says the issue is related to the MfeCcde.sys. For the third party software, its digital signature couldn’t be validated.

    Hope it will be helpful to you.
