Secure Boot Enabled but Not Working | Solved

When Secure Boot is enabled but not working on Windows 11, it often means the system is not fully booting in UEFI mode, which is necessary for Secure Boot to function properly. One common fix is to disable CSM (Compatibility Support Module) in your BIOS settings; this forces the system to boot in pure UEFI mode and activates Secure Boot. Another approach is to reset your platform firmware to Setup mode. This involves entering the BIOS or UEFI Setup and changing the Secure Boot configuration to accept the factory default keys and switch from Audit mode to Standard mode. By doing so, you ensure that Secure Boot checks are properly enforced, thus enhancing system security. Furthermore, while resolving Secure Boot issues, it’s highly recommended to protect your PC from potential data loss or system crashes by using a reliable backup solution such as AOMEI Backupper. This tool offers comprehensive backup options and quick restore capabilities, providing peace of mind during system modifications. Understanding Secure Boot’s role is crucial—it prevents unauthorized operating systems and malicious software from loading during startup, which protects your device from rootkits and boot-level malware. For users encountering these issues, it’s essential to ensure that your BIOS firmware is up to date, as manufacturers often release patches to improve compatibility and Secure Boot functionality. Regularly updating BIOS, combined with correct Secure Boot settings (disabled CSM and Setup mode activation), will stabilize system security on Windows 11 machines. In summary, fixing Secure Boot enabled but not working usually requires two key steps: disabling CSM in your BIOS to enable UEFI booting and configuring Secure Boot to accept default platform keys in Setup mode. Backing up your data using tools like AOMEI Backupper before applying these changes adds an extra layer of security against unexpected failures.
