Secure Boot

[TiagoRossi]

Olá, estou com problema ao ativar o secure boot, quando está ativo esta dando erro: "Secure Boot Violation: Invalid Signature detected. Check secure boot policy in setup."

Eu não consigo usar o computador com o secure boot ativo, gostaria de saber como faço para arrumar esse erro. Vi que tem o UEFI CA 2023, mas para poder instalar no meu Computador preciso que o secure boot esteja ativado, e não consigo ativar ele.

Hi TiagoRossi,

Thank you for reaching out to the Intel Community Forum. To assist us in investigating the issue, please provide the following details:

• Is your system currently booting in UEFI mode or Legacy/CSM mode, and was Windows installed with Secure Boot enabled or disabled?

• In your BIOS setup, what Secure Boot mode is currently selected (Setup Mode, User Mode, or Custom Mode), and do you see any existing Secure Boot certificates in the key management section?

• Does the "Invalid Signature detected" error occur immediately when you enable Secure Boot in BIOS, or only when trying to boot into Windows?

• Have you made any recent hardware changes, BIOS updates, or installed any unsigned drivers/software that might affect boot security?

• Have you tried using the "Clear Secure Boot Keys" or "Reset to Setup Mode" option in your BIOS to restore factory certificate settings?

Additionally, to gain a comprehensive understanding of your system, please use the System Support Utility (SSU). This tool will generate a text file compiling all your system information. You can follow the instructions at this link and send the text file here. Help Guide for the Intel® System Support Utility.
