Step 3
Changing the Boot Order Once you’ve found the boot order settings, you can change the order by using the arrow keys to move the device you want to boot from to the top of the list. For example, if you want to boot from a USB drive, you’ll need to move it to the top of the list.
For computers with UEFI firmware, you may also need to disable Secure Boot before you can change the boot order. This is a security feature that prevents unauthorized operating systems from loading during the boot process. To disable Secure Boot, navigate to the “Security” or “Boot Security” menu in the firmware settings and set Secure Boot to “Disabled.”
