For method 2, how could one do that if the computer came with Vista already installed? Also, I have a CD that came with the computer that says:
Already installed on Your Computer
on the top of the disc.
On the left hand side it says:
The software is already installed on your computer.
Only use this DVD to reinstall the operating system on a Dell PC.
The attached picture is of the top of the disc. The other writing was too small to show up in a picture.
