Windows Boot Manager or simply BOOTMGR is preloaded software, is loaded when Windows starts. It is responsible for you to boot the Windows operating system version 10/8/7 or Windows Vista.
All the configuration information the BOOTMGR requires can be found in the (BCD) store or Boot Configuration Datastore, which is a database in the form of a registry. This database file replaced the boot.ini file used in Windows XP.
The BOOTMGR file is, by default, both read-only and hidden unlike other operating system files because of its sensitive nature. The boot manager file is located in the root directory of the primary partition of the computer. It is, by default, marked as “Active” in Disk Management always. Mostly it is labeled as “System Reserved” in Windows PCs, without the partition name.
If you cannot find any “System Reserved” partition or file then the BOOTMGR is located on the primary hard drive mostly in the C drive. The boot manager is responsible for loading the winload.exe file which is the system loader file that is used to start and continue the Windows boot-up process.

However, in the older version of the Windows operating system, the Bootcfg and NvrBoot files are included and used instead.
