What is the correct boot order sequence in Windows?

1. bootmgr > ntoskrnl.exe > winload.exe

2. winload.exe > bootmgr > ntoskrnl.exe

3. bootmgr > winload.exe > ntoskrnl.exe

4. ntoskrnl.exe > bootmgr > winload.exe

The correct answer is: bootmgr > winload.exe > ntoskrnl.exe

The correct boot order sequence in Windows starts with the boot manager, followed by winload.exe, and then ntoskrnl.exe. Understanding this sequence is crucial as it illustrates how the Windows operating system initializes during the startup process. First, the boot manager (bootmgr) is responsible for loading the operating system. It examines the existing operating systems on the hard drive and presents the user with a boot menu if there are multiple operating systems available. After the user selects an operating system (or if it automatically selects one), bootmgr initiates the process of loading the necessary files to continue booting. Next, winload.exe is the Windows OS loader, which is tasked with loading the operating system kernel (ntoskrnl.exe) into memory. Winload.exe also initializes the hardware abstraction layer (HAL), if present, and loads any essential drivers that ensure hardware is appropriately configured for the OS to run. Finally, ntoskrnl.exe is the Windows NT operating system kernel, responsible for managing system memory, processes, and hardware interactions. At this point, after being loaded by winload.exe, the kernel takes over the operation of the operating system. This sequential flow—bootmgr first, followed by winload.exe, and then ntos
