How to enable USB boot in motherboard BIOS

The motherboard is one of the core components of computer hardware. It is responsible for managing and controlling the operation of other hardware devices. When using a computer, we sometimes need to boot the operating system from a USB flash drive, which requires setting the USB flash drive boot in the motherboard's BIOS.

BIOS is the abbreviation of Basic Input/Output System, which provides the underlying communication interface with the operating system and hardware devices. Through the BIOS, we can adjust various settings of the computer, including USB boot.

To set up USB boot, you first need to enter the BIOS interface of the motherboard. Usually, you can enter the BIOS setting interface by pressing specific keys on the keyboard during the boot process, such as F2, F12, ESC or DEL. There may be some differences between different motherboard brands and models, so it's best to check the motherboard's user manual or manufacturer's website to determine the correct buttons.

After entering the BIOS setup interface, we need to find the startup options. The layout of the interface may vary in different BIOS versions, but there is usually a "Boot" or "Startup" option. After entering the boot options, we can see related setting options, such as "Boot Device Priority", "Boot Mode", "UEFI/Legacy Boot", etc.

First, we need to make sure that "Boot Mode" is set to one of UEFI (Unified Hardware Interface) or Legacy (legacy boot mode). The UEFI boot mode supports the new secure boot mechanism, which can better protect the system and is recommended. The Legacy boot mode is a traditional boot mode and is suitable for older operating systems and hardware.

Next, we need to set the "Boot Device Priority" or similar option. The settings here determine which devices are tried to start first when booting. We set the USB drive as the preferred boot device by moving the USB drive option to the top of the list. Sometimes, we can also use the , - keys or function keys to adjust the order of devices in the list.

In addition, some motherboards also provide options such as "Boot Override" or "Directly Select Boot Device". With these options, we can choose which device to boot from every time we turn on the computer. This is useful for temporarily booting a one-time system or fixing an operating system issue.

After setting up the U disk boot, we need to save the settings and exit the BIOS interface. The BIOS can usually be saved and exited by pressing F10 or selecting the "Save & Exit" option.

After restarting the computer, if everything is set up correctly, the system will boot from the USB flash drive. At this point, we can follow the installation steps of the operating system in the USB flash drive.

In summary, to set the motherboard BIOS to boot the USB flash drive, you need to enter the BIOS interface and set the USB flash drive as the preferred boot device in the startup options. Then save the settings and exit the BIOS, restart the computer to boot from the USB flash drive. In this way, we can easily use the USB flash drive to install the operating system or perform other operations. But please note that before making any BIOS settings, please make sure you have made a backup and operate with caution to avoid data loss or system failure to boot.
