You may need to change the startup sequence to allow the
computer to start from another device or a network location.
- Open the UEFI/BIOS setup utility.
- Navigate to the Boot menu.
- Follow on-screen instructions to change the order of devices
under Boot Priority Order.
Note: You can also change startup sequence temporarily without
opening the setup utility. To do so, start the computer. When the
Lenovo logo appears, press F12 (or Fn + F12) repeatedly.
