The BOOTMGR is a program that runs when you start your PC, and loads your operating system from the hard drive. When it is missing, Windows is unable to boot.
the BootMgr file and the BCD file are stored in the system partition
Bootmgr is installed by default onto your system. Once you create a bootable partition on your hard drive, you should be given the option right there to enable it.
The BOOTMGR (Boot Manager) is stored in the boot sector of the system partition on a Windows system. It is typically located in the first sector of the hard disk.

The Ultimate Boot CD contains diagnostic tools like CPUStress (which tests for computational errors), BOOTMGR (for systems with multiple operating systems installed), and CopyWipe (for copying and erasing hard drives). These are all functional programs which somehow relate to the computer's operation; the UBCD does not contain things like games or graphic design programs.
The Boot Manager (bootmgr) is a critical component of the Windows operating system responsible for managing the boot process. It reads the Boot Configuration Data (BCD) to determine which operating system to load, particularly in multi-boot environments. Additionally, it provides a user interface for selecting different OS options and can initiate recovery tools if necessary. Overall, bootmgr ensures that the correct OS is loaded efficiently and reliably during system startup.
Windows stores the files and folders necessary for booting the computer primarily in the System Reserved partition and the Windows operating system partition. The boot manager and Boot Configuration Data (BCD) are located in the System Reserved partition, while essential system files are found in the Windows directory of the OS partition (usually C:\Windows). Additionally, the boot loader, known as bootmgr, plays a critical role in initiating the boot process.
