How does BIOS work?
The BIOS is a program pre-installed on Windows-based computers that the computer uses to start up. The CPU accesses the BIOS even before the operating system is loaded. The BIOS then checks all your hardware connections and locates all your devices. If everything is OK, the BIOS loads the operating system into the computer’s memory and finishes the boot-up process.
Menu Options available on BIOS settings.
You view and manage below settings on any Windows based BIOS. Usually you may find below menu options on BIOS screen. BIOS has a Setup utility stored in the BIOS flash memory. The configured data is provided with context-sensitive Help and is stored in the system’s battery-backed CMOS RAM. If the configuration stored in the CMOS RAM is invalid, the BIOS settings default to the original state specified at the factory.

The boot menu allows a user to load up other operating systems or applications, even if the computer itself already has an operating system on it. It is also useful when trying to install a new operating system on a computer, and the user needs to load the installation application from a CD or DVD.
How to boot into BIOS
To boot into BIOS you may have to power on the computer and press keys on computer. More specifically, it depends on the motherboard, as this is where the BIOS is located. Common keys to enter the BIOS are F1, F2, F10, DEL, ESC, as well as key combinations like CTRL + ALT + ESC or CTRL + ALT + DEL, although those are more common on older machines.
