Am at a loss as to installing Kubuntu 12.04 as dual boot with Ubuntu 10.04. Have attempted it several times & end up with the original Ubuntu install. After web searching I find little or no info on this topic. Maybe someone can suggest sources. Am using amd64 bit processor, 500G drive NVidia GTX 550 Ti processor, 8G ram. Sure could use some constructive help, which seems lacking re KDE net sources.
