Ok so you have a blank drive then. Un hook that hdd, put ssd in machine by itself, use the w10 media, enter the key when it asks you to. Make sure the partition uses entire drive (windows may reserve 100MB for itself during install-leave that alone)
Otherwise you may need to install magic disk now on your existing drive and do a secure erase on the ssd itself, which you can then do the firmware upgrade.
May I have the link for that, I searched Magic Disk all that shows up is MagicISO.
