I downloaded Linux ubunto onto my desk top and moved it to a DVD disk. Now I try to open it from the Disk onto my computer. I'm wanting to try it from the Disk before installing it on my computer. When I try it has burning on the brain. All it wants to do is burn it on another dvd. How can I get it open and run from the dvd ? THanks

First, did you burn it as a data file or as an image file? (The latter is what you want.)

Second, to run the live CD, assuming it is burnt correctly, you need to change the boot order of your computer from the BIOS, so it boots from the CD.

I'm don't know how to change BIOS to boot from the dvd. Could you give a bit more help in that respect ? Also could I readily switch from booting from the dvd back to my Windows 7 ? Thanks

its difficult to tell you exactly how to change it, we don't know what BIOS your computer has, typically right when you turn on your computer to enter the BIOS there is a button you have to press, usually one of the F1-F12 keys or the Delete key. From there you would have to find a screen where you can set the boot order and put the cdrom device first.
