Choose:

Insert your USB drive and follow the instructions

Insert the bootable USB drive into your PC
Restart the computer
Enter BIOS/UEFI (usually by pressing F2, F12, DEL, or ESC during startup)
Set the USB drive as the first boot device
Save changes and exit

Your PC should now boot from the USB drive.
