What is Booting?
Booting is the process your computer goes through when it's powered on, where it loads the operating system (like Windows, Linux, or macOS) so you can use the machine.
Boot Process (Simplified):
- Power On – You press the power button.
- POST (Power-On Self-Test) – The system checks basic hardware like RAM and CPU.
- BIOS/UEFI Loads – The firmware runs and looks for a bootable device (hard drive, SSD, USB, etc.).
- Bootloader Launches – A small program (like GRUB for Linux or Windows Boot Manager) loads the OS.
- Operating System Starts – The core OS files load into memory, and the login screen appears.
Types of Booting:
- Cold Boot – Turning on a computer from a powered-off state.
- Warm Boot – Restarting the computer without turning it off (e.g., pressing Ctrl+Alt+Del).
- Network Boot – Booting from a server instead of a local drive.
