• Boot Order: It determines the order in which your computer attempts to boot from different storage devices (e.g., hard drive, USB drive).
• System Settings: It allows you to configure various system parameters, including the date and time, boot options, and security settings.
• POST (Power-On Self-Test): The BIOS runs a self-test to check for any hardware issues.
