The distribution DVD media and the Live CD media offer an option to verify the integrity of the media. Recording errors sometimes occur while producing CD or DVD media in home computer equipment. An error in the data for package chosen in the installation program can cause the installation to abort. To minimize the chances of data errors affecting the installation, verify the media before installing.
If you boot from the Live CD, choose Verify and run from image from the boot menu. The verification process runs automatically during the boot process, and if it succeeds, the Live CD continues loading. If the verification fails, create a new Live CD using the ISO image you downloaded earlier.
