I do not have the Hero board, I have the Extreme version - did you enable the M.2 slot in bios?
Are you planning on using that drive as your OS drive? If yes I would strongly suggest you remove all other drives or storage devices from your system before starting the OS instillation. Windows has this horrible habit of sticking needed partitions where it wants to and not where we would like them to go. So if you are using that new SSD for your OS give what I said some thought.
To help us help you - please provide as much information about your system and the problem as possible.
