I have GK208B [GeForce GT 730] GPU with nVidia driver v: 470.141.03 on installed OS
Live ISO non-free option only uses latest nVidia driver that cannot work on a Kepler GPU
free is the only option capable of booting to desktop with legacy GPU
nVidia legacy driver can be installed after OS installed
sudo mhwd -i pci video-nvidia-470xx
Or Manjaro Settings Manager > Other Hardware GUI – manjaro-settings-manager -m msm_mhwd
