Study Notes

Errors in the Boot Process

Problems during the boot process can arise from new software or hardware installations. Uninstalling the recent addition may resolve boot issues.
Access the Windows Advanced Options Menu if boot problems occur, which offers options like Last Known Good Configuration. This uses the saved registry information from the last successful shutdown.
For Windows 10, the "Reset your PC" feature can attempt to fix system file errors influencing improper behavior.

Performing the Power-On Self Test (POST)

The boot process begins with the CPU activating the BIOS, which manages data exchange between the operating system and connected devices.
The first procedure is the Power-On Self Test (POST), ensuring all peripheral devices are attached and functional.
POST tests include checking the video card, verifying the BIOS, and ensuring memory chips are operational, comparing results with configurations stored in CMOS.

Loading the Operating System (OS)

Upon successful POST, BIOS loads the operating system from the hard drive into RAM, followed by the kernel, the essential OS component managing processor and system functions.
The kernel remains in RAM while other non-critical OS programs are loaded as needed from the hard drive.
After loading the kernel, the OS checks the registry for configurations and customized settings before presenting the desktop, indicating readiness for user commands.

Steps of the Boot Process

Step 1 involves the CPU activating BIOS stored in ROM, which retains data even when powered off.
Step 2 sees BIOS conducting POST to confirm all devices are connected and functioning properly before proceeding.
Step 3 entails BIOS searching a configured list for the appropriate storage drive with system files, which are loaded into RAM.
Step 4 requires the OS to check the registry for additional configurations and customizations before the desktop is displayed.

Definitions and Processes

A good solution for boot issues may include uninstalling recently added software or hardware until the problem resolves.
The boot process guarantees that the operating system is loaded into RAM for operation.
The first action in the boot process involves the CPU accessing the BIOS.
Following BIOS activation, it verifies that peripheral devices are connected and functional.
After POST confirmation, the operating system is copied from the hard drive to RAM.
The kernel, central to the operating system, oversees processor and component management.
Even with the kernel loaded, the OS must still check the registry before the computer is fully operational.
