MacPostFactor El Capitan Unknown Error

[rp107]

I wanted to use MacPostFactor when I wanted to update to a newer os on a older mac. I got all the files ready and loaded. When I was installing, I had some trouble, but i figured it out. When I continued installing El Capitan using MacPostFactor. It started to install El Capitan, but about 20 second in it says this

If I have to go back to Lion, that is fine since I have a boot drive, but does anyone know how to fix this, or know what this problem means.
