did you have .iso file – Avinash Raj Nov 11 '13 at 17:25

Try this. Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo dd if=/dev/sdx of=<file_name>.iso

Note: Make sure that you replace the X with the right device number.

Once you have the ISO file, you can burn it to CD. On a personal note, I would recommend that you download the ISO from Ubuntu if that is all possible, and burn the CD that way.
