BIOS Looks for the MBR on the bootable device

3

Through the MBR the boot sector is located and the BOOTMGR is loaded

4


NTLDR reads BOOT.INI from the system volume to determine the boot drive


BOOTMGR reads the BCD (boot configuration database) file from the \boot directory

5


NTLDR loads and executes NTDETECT.COM from the system volume to perform BIOS hardware detection


BOOTMGR transfer control to the Windows Loader (winload.exe) or winresume.exe in case the system
was hibernated.

6


NTLDR reads the registry files, selects a hardware profile, control set, and loads drivers flagged as "boot" defined in the system hive, then passes control to NTOSKRNL.EXE


Windows Loader loads drivers that are set to start at boot and then passes control to NTOSKRNL.EXE
