Problem: The computer does not start from a device you want.
Solution: See the Startup menu of the BIOS Setup Utility. Make sure that the

included in the ″Excluded from boot order″ list, it is disabled. Select
the entry for it in the list and press the x key. This moves the entry
to the ″Boot priority order″ list.
