I know there is no operating system on my computer, I had the HD 100% wiped. I was intending for Ubuntu to be my operating system. Am I to assume I cannot install from a DVD because I have no operating system? Is there something I'm missing? I tried with Puppy Linux too, because I believed that could be operated from the disc. Same thing, "No operating system".

do you forgot to change the boot device to CD in your bios? – Paolo Mar 8 '14 at 23:51
How did you get Ubuntu .iso onto the DVD? Did you just copy the large file onto the DVD, or did you re-create the original disk structure that the Ubuntu .iso is an image of? – Marc Mar 9 '14 at 0:16

Like the comments above change the boot order from the bios so that it boots from disk first.
