Explanation & Hint:
To understand the sequence of steps leading to the loading of bootmgr.exe in a 32-bit Windows 10 environment, let’s break down each step:
- POST (Power-On Self-Test) executed: This is the first step when a computer is turned on. POST is a diagnostic testing sequence run by the computer’s firmware (BIOS or UEFI) to check the hardware components like memory, disk drives, and other hardware to ensure they are working correctly.
- CMOS configuration settings loaded: After the POST, the BIOS/UEFI firmware loads the CMOS configuration settings. CMOS (Complementary Metal-Oxide-Semiconductor) stores information like system time, date, and hardware settings. The BIOS/UEFI uses these settings to understand the system’s configuration.
- MBR (Master Boot Record): The MBR is the first sector of the hard drive that the BIOS/UEFI reads after it has determined which storage device to boot from based on the CMOS settings. The MBR contains information on how the hard drive is partitioned, as well as a small amount of code to start the boot process.
- VBR (Volume Boot Record): After reading the MBR, the system proceeds to read the VBR of the active partition. The VBR, also known as a partition boot sector, contains the code to load the operating system’s bootloader. In the case of Windows 10, this bootloader is
bootmgr.exe .
So, the correct order to load bootmgr.exe in a 32-bit Windows 10 environment is:
- POST executed.
- CMOS configuration settings loaded.
- MBR read.
- VBR read, leading to the loading of
bootmgr.exe .
