Attached is the file that contains the all requirements for this Assignment.

Please follow the following 3 steps, this homework requires a computer with Microsoft Windows:

Step-1: read the following points to understand the boot process:

1- When the computer is first powered on, programs stored in nonvolatile firmware known as BIOS completes some low-level tests of the hardware first then run a small boot loader that also exists in the BIOS.

2- BIOS cannot simply load a file that represents your operating system from a disk, since BIOS has no notion of a file system. Thus, the small boot loader in BIOS will read the first sector (i.e., Cylinder 0, Head 0, Sector 0) of all the disks (hard disk, USB disk, CD ROM, DVD ROM, etc.).

3- If the last two bytes of a sector (a sector is 512 bytes) are 0xaa55 (magic number) then this is called a boot sector and the disk containing this sector is a bootable disk and has an operating system. Otherwise, it is a disk used for storing data like external hard disks or USB flash drives without an operating system.

4- Once a boot sector is identified (and thus the disk containing that sector is selected for booting), the small boot loader loads this boot sector to address 0x7C00 in memory and switch execution to this code. At this point, the memory of your computer will be as shown in the figure on next page:

5- The program stored in the boot sector may be sophisticated enough to load the entire operating system into memory and begin its execution. However, 512 bytes is not much to hold a large program, so this area may contain a simple boot loader that will not be able to load the operating system. Consequently, this (second) boot loader will load another (third) boot loader from a disk knowing the address on disk and the length of that third boot loader.

Many recent computer systems have replaced the BIOS-based boot process with UEFI (Unified Extensible Firmware Interface).

Step-2: read the following article except the last 2 sections named “Move 2” and “Move 3”:



Step-3: Following the steps in the above article, use your phone or any camera to take pictures for the following:

1- Picture for your computer.

2- Two pictures for your UEFI Firmware Settings or BIOS on your computer showing the Main Menu and the Boot Menu. Note that on window 11: click on System under settings then Recovery then click on Restart now to access the UEFI Firmware or BIOS.

3- Picture showing BIOS Mode (Legacy or something else) on your Microsoft Windows (System Information).

Put all the pictures on a word document with your name and submit it.
