Turns out the Nvidia iso is an older one right now, and so there are a few problems with it.
When the installer is run, it crashes at the user creation screen saying it “Cannot create download package list (metalinks)” To solve this, simply open the terminal and type:
su find /usr/share/cnchi -type f -print0 | xargs -0 sed -i 's/lib32-mesa-libgl/lib32-mesa/g'
After this, the issue should be solved
Hope this helps and good luck!
