Ubuntu – How to validate an installation DVD

checksumsdiskinstallationisovirtualbox

I have downloaded an Ubuntu ISO and burned it to DVD. While installing from the DVD onto VirtualBox I got an error which suggested either the HDD or DVD or overheating were the cause. I am investigating all three. How can I verify that the DVD has been correctly burned (I still have the original ISO file)?

Best Answer

While the installation DVD loads, for a while your should see a image with a hand and a keyboard at the bottom.

Press any key while this image is showing and a menu with the installation options will open. You will find there an option to check the media.
