I downloaded from first link on http://lubuntu.net/ Burned a DVD with CD Burner XP in another PC , and at the main computer changed BIOS boot setting to look at CD DVD driver first. Now at the main computer there is an old Ubuntu 8 Hardy Heron. There is no direction when i put new burned DVD at DVD driver. Where am i wrong? Is there something that i misunderstand, for example lubuntu is really an OS which can be installed on harddisk?
