Fix 1. Use Auto Repair
Windows 11 offers an automated repair feature to fix unmountable boot errors. The "Auto Repair" utility, part of the Windows installation media, can troubleshoot and resolve boot-related issues on its own. To access this feature, users can use the Windows 10/11 installation media, which will guide them through the process to automatically repair the boot issue.
