An accountant is booting a PC that has Windows 10 installed. The boot process is currently working on the following step: BIOS locates and reads the configuration settings that are stored in the CMOS memory. What is the next step that will happen in the boot process?
- The BIOS boots the computer using the first drive that contains a valid boot sector.
- WinLoad reads the registry files, chooses a hardware profile, and loads the device drivers.
- The Windows kernel takes over the boot process.
- WinLoad loads two files that make up the core of Windows: NTOSKRNL.EXE and HAL.DLL.
Explanation: The Windows 10 boot process is as follows:
1 . PreBoot: POST or Power-On Self-Test loads firmware settings. It checks for a valid disk system, and if the system is good to go for the next phase. If the computer has a valid MBR, i.e. Master Boot Record, the boot process moves further and loads Windows Boot Manager.
2 . Windows Boot Manager: This step determines if you have multiple OS installed on your computer. If yes, then it offers a menu with the names of the OSs. When you select the OS, it will load the right program, i.e. Winload.exe to boot you into the correct OS.
3 . Windows OS Loader: WinLoad.exe loads important drivers to kick start the Windows Kernel. The kernel uses the drivers to talk to the hardware and do rest of the things required for the boot process to continue.
4 . Windows NT OS Kernel: This is the last stage which picks up the Registry settings, additional drivers, etc. Once that has been read, the control is taken by the system manager process. It loads up the UI, the rest of the hardware and software. That’s when you finally get to see your Windows 10 Login screen.
