Thank you for contacting the Intel Communities.
I would like to know, is the keyboard or mouse wireless or wired?
Since a fresh install just has been done, chances are that drivers for a wireless keyboard and mouse dongle haven't been loaded.
Just to make sure, please test it with a wired keyboard and let us know if the issue persists.
Additionally, if you require any further information or support, feel free to contact us back.
Thank you for your answer.
I would like to double check if you were following these instructions for this task.
I would also like to recommend you to follow the steps in troubleshooting.
