Enable or disable Windows Boot Manager on Windows 11/10

In this post, we will show you multiple methods to enable or disable Windows Boot Manager on Windows 11/10.

Windows Boot Manager (BOOTMGR) is one of the main components of the Windows OS that configures the boot environment. It is responsible for managing the boot sequence, initiating the startup of the operating system, and dealing with boot-related errors. It is especially useful when there are multiple operating systems installed on your PC. When you start or restart your PC, you can choose which OS you want to load.

Now, if you want to disable Windows Boot Manager to reduce the overall time spent booting a system, you can do that. Although it is not recommended to do so, it significantly speeds up the boot process. Besides that, Windows also lets you edit the time duration for how long that BOOTMGR will be displayed.
