The volume boot code, which is part of the volume boot record, is used to load Windows Boot Manager. It aids with the startup of your Windows 10, Windows 8, Windows 7, or Windows Vista operating system.
Boot Manager—often abbreviated as BOOTMGR—eventually launches winload.exe, the system loader needed to finish the Windows boot process.
Where Can I Find the Windows Boot Manager?
The Boot Configuration Data store, a registry-like database that replaced the boot, contains the configuration data necessary for Boot Manager. In prior versions of Windows, such as Windows XP, an ini file was utilised.
The BOOTMGR file is both read-only and concealed. It is located in the root directory of the Active partition in Disk Management. This partition is designated System Reserved on most Windows machines and does not get a drive letter.
If you don’t have a System Reserved partition, BOOTMGR is most likely on your main disc, which is often C. For More Information You Can Visit TrendBlog
Is it possible to disable Windows Boot Manager?
The Windows Boot Manager cannot be removed. You may, however, shorten the time it waits for you to respond which operating system you wish to start by selecting the default operating system and then decreasing the timeout duration, thereby bypassing the Windows Boot Manager entirely.
To change the default behaviour, use the System Configuration (msconfig.exe) tool.
1. Open Administrative Tools, which may be accessed via the System and Security link in the Control Panel.
2. Open System Configuration
3. Select the Boot tab on the System Configuration window that opens.
4. Select the operating system to which you wish to always boot.
5. Adjust the Timeout time to the lowest possible time, in seconds, which is probably 3
6. Choose OK or Apply to save the changes
The BOOTMGR Is Missing issue is a common starting problem in Windows.
In previous versions of Windows, such as Windows XP, BOOTMGR, together with winload.exe, replaces the 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 multi-boot situation, the Windows Boot Manager loads and reads and applies the specific settings that relate to the operating system installed on that partition.
If the Legacy option is selected, the Windows Boot Manager launches NTLDR and proceeds with the boot process as if it were booting any version of Windows that utilises NTLDR, such as Windows XP. If there is more than one pre-Vista installation of Windows, another boot menu (derived from the contents of the boot.ini file) is provided so that you can choose one of those 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 may manage boot options.
You can alter the boot choices on Windows Vista and subsequent versions of Windows as long as you’re in the Administrators group, using the BCDEdit.exe utility provided in those versions of Windows. If you’re using an older version of Windows, you’ll need to use the Bootcfg and NvrBoot utilities instead.
