Study Notes
Booting Process
- Booting is the process of initializing and starting a computer.
- This involves critical stages to prepare hardware and software for use.
- It starts from a powered-off state.
- The operating system is loaded into memory.
Types of Booting
- Cold booting: Starting a computer for the first time or after a complete shut down.
- The computer reads the Basic Input/Output System (BIOS) instructions stored in the ROM.
- Warm booting (rebooting): Restarting a computer while it's on.
- Usually performed when the system hangs or becomes unresponsive.
- Can be initiated via hardware (e.g., pressing a reset button) or software commands (e.g., Ctrl+Alt+Del).
Pre-Boot Environment (PBE)
- The pre-boot phase (PBE) occurs before the operating system (OS) is loaded into memory.
- During this stage, hardware is initialized, and the system checks if it's ready to load the OS.
Key Components of PBE
- BIOS (Basic Input/Output System) and UEFI (Unified Extensible Firmware Interface): Firmware interfaces stored on the motherboard. They serve as the initial software layer interacting with the hardware.
- Role of BIOS/UEFI: Initialize hardware components, establish basic communication with input/output devices (like keyboard, mouse, display, and storage).
- POST (Power-On Self Test): Series of diagnostic tests performed by BIOS/UEFI.
- Purpose of POST: Verify essential hardware components (e.g., CPU, RAM, storage) are functioning correctly.
- If problems are detected, an error message/beep code is generated.
Differences between BIOS and UEFI
- Modernity: UEFI is more modern and flexible compared to BIOS.
- Interface: UEFI can have a graphical user interface, whereas BIOS is text-based.
- Storage support: UEFI supports larger hard drives due to advancements like GPT partitioning (hardware dependent). BIOS is limited to smaller capacities.
- Boot Speed: UEFI generally has faster boot times compared to BIOS.
- Networking: UEFI can support network booting capabilities, while BIOS has limited support.
Common Boot Issues and Troubleshooting
- Hardware failure (RAM, hard drive, CPU): Could be the reason for the computer not booting.
- Corrupted boot files: Issues with the operating system files.
- Incorrect BIOS/UEFI settings: Problems with the configuration of the BIOS or UEFI.
Example Scenarios and Steps
- Scenario 1 (Cold Boot): Starting a computer for the first time. Steps describe pressing the power button, waiting and turning on.
- Scenario 2(Warm Boot): System hangs. Steps outline restarting the computer via the Start Menu, saving necessary data, and starting again.
Common Boot Problems:
- Incorrect BIOS/UEFI settings
- Corrupted boot files
- Hardware failure
- UEFI/BIOS incompatibility
