Is this a Ryzen system? If so, after inserting the ISO through the web interface, go onto your IMPI and access HTML5 Remote Console like you have right now.
Then restart the server via the web interface or the IMPI. During booting, right after the "white supermicro" screen disappears, you should see in the top something like "Press any key to continue....".
As the message states, press any keyboard key and that will launch you into the Windows installer. ๐
