A company is investigating an issue with one of their Windows servers that fails to boot up. The IT forensics team is called upon to determine the cause of the issue. According to the standard Windows Boot Process (BIOS-MBR method), what is the likely issue if the system fails right after the BIOS completes the power-on self-test (POST) and before the master boot record (MBR) is loaded?
If the system fails right after the BIOS completes the power-on self-test (POST) and before the master boot record (MBR) is loaded, the likely issue is that the system boot disk is not detected. This is because, after completing the POST, the BIOS scans for a valid system boot disk to load the MBR. If the boot disk is not detected, the MBR cannot be loaded, preventing the system from proceeding with the boot process.
B < Once the BIOS POST and AddOn ROM procedures have completed, the BIOS loads the first 512 bytes from the hard drive of the selected boot device – these 512 bytes are what is commonly known as the MBR, or the Master Boot Record.
3. If POST is successful, add-on adapters perform a self-test for integration with the system 4. The pre-boot process is completed with POST, detecting a valid system boot disk 5. After POST, the computer’s firmware scans the boot disk and loads the master boot record (MBR), which searches for basic boot information in Boot Configuration Data (BCD)
