About BOOTNGR

BOOTMGR, short for Windows Boot Manger, is a small piece of software located on either the system or the boot partition that helps Windows 10, Windows 8, Window 7 and Windows Vista operating system start.

How does it work?

For Windows Vista, the boot sector or UEFI loads the Windows Boot Manager, accesses the BCD store and uses the information to load the operating system. Then the BCD invokes the boot loader to initiate the Windows Kernel. 

To be more specifically, the booting process is:

BIOS-->MBR-->DPT-->PDR--> BOOTMGR-->BCD-->Winload.exe-->Windows Kernel-->whole operating system

Please note that if there are multiple operating systems in your computer, you will get an interface for selecting the operating system to load in a few seconds.
