Hello gloxdog and welcome to the forums, Well as I see it Looks like your gonna need a bigger stick !
or may be a external DVD/player/burner, As Ultimate Edition 2.3 Is 9.04 jaunty, AND has It,s own integral upgrades, That are not a basic part of a Ubuntu stock install, It is all way's recommended to do a fresh install of Ultimate Edition,As When TheeMahn and the team build Ultimate Edition The new release is all way's fresh, not a hack of the previous release!
and It more than likely will have its own integral upgrades,This Is one of the reasons we tell everyone to back up there home data often ! I would also recommend using the advanced search option here on the forum, As there are several other posts on this subject, as well as how to back up, install ,and restore some of your basic needs , how ever If you are really stuck with what you have, you can all way's make your Ubuntu Look Like Ultimate Edition via theme's and icon changes and upgrades, the theme's are available here under theme's and logo's , also available at Gnome-Look, Others may have more input on this, But that's the way I see it !
Good Luck my friend ! come back and visit often !
