USB optical drive, or internal optical drive) are checked for a bootable operating system image.

To boot one time from a device other than the default device specied in Boot Order, restart the computer
and press Esc (to access the Startup menu) and then F9 (Boot Menu), or only F9 (skipping the Startup

from the selected non-default device for this one time.
