Secure Boot is a vital security feature in modern computers that ensures the operating system and other software are loaded securely, preventing malicious code from running during the boot process. However, what happens when your Secure Boot becomes unsupported? In this article, we’ll delve into the world of Secure Boot, explore the reasons behind an unsupported Secure Boot, and provide you with a comprehensive guide on how to troubleshoot and resolve the issue.
Understanding Secure Boot
Before we dive into the troubleshooting process, it’s essential to understand how Secure Boot works. Secure Boot is a feature that was introduced in 2012 with the release of Windows 8. It’s a part of the UEFI (Unified Extensible Firmware Interface) firmware that replaces the traditional BIOS. Secure Boot ensures that the operating system and other software are loaded securely by verifying their digital signatures against a set of trusted certificates stored in the UEFI firmware.
Secure Boot uses a combination of keys and certificates to verify the authenticity of the operating system and other software. The UEFI firmware contains a set of trusted keys, known as the Platform Key (PK), Key Exchange Key (KEK), and Database Key (DB). These keys are used to verify the digital signatures of the operating system and other software. If the digital signature is valid, the UEFI firmware allows the operating system to boot. If the digital signature is invalid or missing, the UEFI firmware will prevent the operating system from booting.
Types Of Secure Boot
There are two types of Secure Boot:
- UEFI Secure Boot: This is the most common type of Secure Boot, which uses the UEFI firmware to verify the digital signatures of the operating system and other software.
