Microsoft has addressed a significant issue that impacted users running Windows 11 alongside Linux distributions like Ubuntu, Debian, Mint, and Zorin. The problem, which emerged nine months ago with the August 2024 security update, has now been officially resolved through specific updates.
Comprehend the issue
The KB5041585 patch, launched in August last year, initiated a modification in Secure Boot Advanced Targeting (SBAT), a security feature that restricts boot managers deemed outdated or unsafe by utilizing the Secure Boot DBX database.
Many Linux systems have experienced issues where they fail to boot properly, showing error messages.
Failure to verify the data of shim SBAT constitutes a breach of the Security Policy.
Microsoft suggested a different solution that required complex modifications to the Windows Registry, which may be challenging for average users.
What is Microsoft’s statement regarding the error?
The company acknowledged that in certain instances, the dual boot detection system did not function as intended.
Dual boot detection on certain devices failed to recognize custom methods and incorrectly applied the SBAT value.
The system discovered that Linux was not installed on the computer, causing it to prevent the other system from starting up.
The issue is resolved by the update released in May 2025.
Microsoft released an update nearly one year later to fix the issue. The new patch from the company ensures that SBAT no longer interferes with Linux booting, even in cases of custom dual boot setups, commonly used by advanced users and developers.
The update is available for installation through Windows Update and is also included in the official Microsoft update catalog.
