I spent a frustrating morning trying to install Ubuntu on a system for a relative. The install kept failing, so I resorted to testing the CD. It did not pass. I burned two more and they failed as well. I created a lean virtualbox on my desktop system and tested the disks by booting on them then testing them and they were good, which lead me to replace optical drive in the box I was working on.
So, the question is, is there another way to get the CD and/or the ISO. My lean virtualbox seems to work great, especially for disks that I may send in the mail.
