can you give us a list of parts in PC?
was the error "No device drivers were found" as that is likely referring to the USB.
Was the Windows 10 thingy a USB drive? Do you have another 16gb USB handy? On another PC, download the
Windows 10 media creation tool and use it to make a win 10 installer on USB
the cause could be the USB drive itself, windows doesn't have necessary drivers for it.
It is also possible that the store sold copy of Win 10 isn't the newest version of win 10 and depending on what hardware you have, that version may be missing drivers. The version of windows available on Media creation tool is the very latest.
