What is Windows Boot Manager (BOOTMGR)?
The volume boot code, which is part of the volume boot record, is used to load the Windows Boot Manager. It makes it easy to start your Windows 10, Windows 8, Windows 7 or Windows Vista operating system.
The Boot Manager, often abbreviated as BOOTMGR, eventually launches winload.exe, the system loader needed to complete the Windows boot process.
Where can I find Windows Boot Manager?
The Boot Configuration Data Store, a registry-like database that replaced boot, contains the configuration data needed by the boot manager. In previous versions of Windows, such as Windows XP, an ini file was used.
The BOOTMGR file is both read-only and hidden. It is located in the root directory of the active partition in Disk Management. This partition is designated as system reserved on most Windows machines and is not given a drive letter.
If you don’t have a system reserved partition, BOOTMGR is most likely on your primary disk, which is often C. For more information, you can visit TrendBlog
Is it possible to disable Windows Boot Manager?
Windows Boot Manager cannot be removed. You can, however, shorten the time you wait before you respond to the operating system you want to boot by selecting the default operating system and then decreasing the timeout duration, bypassing the task manager entirely. Windows startup.
To change the default behavior, use the System Configuration Tool (msconfig.exe).
1. Open Administrative Tools, accessible via the System and Security link in the Control Panel.
2. Open System Setup
3. Select the Startup in the system configuration window that opens.
4. Select the operating system you always want to boot to.
5. Adjust the Free time time at the lowest possible time, in seconds, which is probably 3
6. Choose OKAY or Apply to save changes
The BOOTMGR Is Missing issue is a common boot problem in Windows.
In previous versions of Windows, such as Windows XP, BOOTMGR, along with winload.exe, replaces functions handled by NTLDR. Winresume.exe, the Windows resume loader, is also new.
When at least one Windows operating system is installed and chosen in a multiboot situation, Windows Boot Manager loads, reads, and applies specific settings related to the operating system installed on that partition.
If Legacy is selected, Windows Boot Manager launches NTLDR and continues the boot process as if it were booting any version of Windows that uses NTLDR, such as Windows XP. If there are multiple pre-Vista installations of Windows, an alternate boot menu (derived from the contents of the boot.ini file) is provided so that you can choose one of these operating systems.
The Boot Configuration Data Store is more secure than earlier versions of Windows Boot Choices because it allows users in the Administrators group to lock down the BCD store and grant specific access to other users to choose who can manage boot options.
You can change startup choices on Windows Vista and later versions of Windows while you are in the Administrators group, using the BCDEdit.exe utility provided in those versions of Windows. If you are using an older version of Windows, you will need to use the Bootcfg and NvrBoot utilities instead.
