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.

Mostly it is labeled as “System Reserved” in Windows PCs, without the partition name. It is, by default, marked as “Active” in Disk Management always. The boot manager file is located in the root directory of the primary partition of the computer. The BOOTMGR file is, by default, both read-only and hidden unlike other operating system files because of its sensitive nature. This database file replaced the boot.ini file used in Windows XP. It is responsible for you to boot the Windows operating system version 10/8/7 or Windows Vista.Īll 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. Windows Boot Manager or simply BOOTMGR is preloaded software, is loaded when Windows starts.
