About the Alternate CD

The text based alternate installer can be downloaded from the various download methods above. This installation CD is suited for computers unable to run the graphical desktop based installation, either because their computer does not meet the minimum requirements for the live CD or because their computer requires configuration after the installation is complete in order to use the desktop. The alternate installer also includes advanced features such as LVM support.


About the DVD

Do not be confused, even though DVDs can hold far more data than the typical Kubuntu CD, the main benefit of the DVD downloads is to get access to all of the available language packs during install. Most people will be fine with the standard CD installer. The DVD includes both the live image/desktop installer and text based alternate installer.
