If you copy the contents, it will not be a bootable one. The same applies if you copy the contents to a DVD directly. You need to embed boot information manually or use the following software. It will create bootable pen -drive.

Use the software wintoflash.

Download the software from above link.

Run the software.

If you have the Vista installation DVD, select it as source and give the destination to your pen drive. Or if you have ISO image select the image as source. (Note: If you don’t have dvd drive use your friend’s computer to do this step.)

Now restart the computer and change boot priority to removable disk.

And see that your operating system getting booted from pen drive.

Also if you need to create bootable DVD, select copy dvd to dvd in your burning software. Do not by mistake copy the contents directly into DVD this will be a waste.

Hope this works. If problem persists in this method or do you have any further queries feel free to write it to me.
