4.3. Verifying Media

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.

[Tip] BitTorrent Automatically Verifies File Integrity

If you use BitTorrent, any files you download are automatically validated. If your file completes downloading you do not need to check it. Once you burn your CD or DVD, however, during the installation you should still use mediacheck to verify the integrity of the media.

4.3.1. Verifying the Live CD

If you boot from the Live CD, choose Verify and Boot 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.

4.3.2. Verifying the DVD

If you boot from the Fedora distribution DVD, the option to verify the media appears after you choose to install Fedora. If the verification succeeds, the installation process proceeds normally. If the process fails, create a new DVD using the ISO image you downloaded earlier.
