If I knew how to edit my last post I would not be making so many...
I went ahead and used gparted to reformat the mounted drive at a FAT32, and recopied the file system from the github.
So far so good. I tried the captive portal payload, and all is working well.
I fear the original problem has to with the tool installation, Ill work on that next.
