This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  1. Download Imgburn.

  2. Install it.

  3. Now run the software.


  4. Select "Create image file from disc".


  5. Select the "source". It's your DVD writer.


  6. Select the "Destination".


  7. Click this icon.


Wait for your image file to be created. Finally, you get an iso file in the destination folder. Now, burn that to a USB and you are good to go.

Hope it helps you.

You need to create an ISO from the DVD. To do you can use ImgBurn. See image below.

enter image description here

Once created you can use Unetbootin to create the bootable USB

It will be better to just download the latest Ubuntu (14.04 LTS) than to create an ISO from that 12.04 DVD - Download here

However, if for whatever reason you want 12.04, you can get the ISO here
