3. Under the Boot menu, find the **Boot Order** or **Boot Priority** option, which may be listed as **First Boot Device**, **Boot Device Priority**, or similar.

4. Use the arrow keys to highlight the option related to **USB** or **Removable Devices**, and then press the designated key (usually the plus or minus key) to move it to the top of the boot order. This will prioritize USB devices for the boot process.

5. Save the changes made in the BIOS by locating the **Save & Exit** or **Exit** options, usually found at the bottom of the screen. Select this option, and confirm your choice when prompted.

6. Your laptop will now restart, and if a bootable USB device is connected, it should boot from it. If not, you may need to enable the **USB Boot** option in the BIOS setup.
