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.
