How can one access the BIOS setup utility?

Accessing the BIOS setup utility typically involves pressing a designated key during the initial stages of the computer's boot process. This key varies by manufacturer, commonly being F1, F2, DEL, ESC, or similar, and is often displayed on the screen briefly when the computer is starting up.

The purpose of entering the BIOS setup is to configure low-level settings for the hardware components of the computer, manage boot options, and make adjustments to system settings that are not available within the operating system itself. This environment is crucial for troubleshooting hardware issues, changing boot sequences, or enabling/disabling specific hardware features.

While turning on the computer involves pressing the power button, doing so does not directly provide access to the BIOS setup itself. Entering Windows settings or using the command prompt pertains to operating system-level configurations and does not facilitate access to BIOS.
