How to fix "Secure Boot State Unsupported" error in Windows?

Issue: Hello. I tried upgrading my PC to Windows 11 but I got the “Secure Boot State Unsupported” error. How do I fix this?

Solved Answer

Secure Boot State is a security feature built into modern computer systems, including Windows PCs, that prevents unauthorized firmware, operating system, and driver software from running during the boot process. It ensures that only digitally signed and trusted applications can be loaded and executed, lowering the risk of malware or unauthorized software being installed on the computer.

When you enable Secure Boot, the system verifies the digital signatures of the boot loader, kernel, and other critical components before allowing them to run. Secure Boot prevents any component from loading if it lacks a valid signature or is not recognized as trustworthy, thereby increasing system security. In recent years, this feature has become a standard security measure and is usually enabled by default on most computers.

Users may encounter the “Secure Boot state unsupported” error message when upgrading to a new operating system, such as Windows 11. When the system's Secure Boot feature is not supported or recognized by the Windows installer or other boot-related processes, this error occurs. As a result, users may encounter issues during the installation process, and in some cases, they may be unable to complete the upgrade.

Users may need to check their computer's firmware settings (BIOS or UEFI) to see if Secure Boot is enabled and supported in order to resolve the “Secure Boot state unsupported” error. If Secure Boot is not supported, users may need to consider other options, such as upgrading their hardware to a compatible system that supports Secure Boot or reverting to a previous operating system version that is compatible with their current hardware configuration.
