Hello stealthster, Welcome to the best Windows forums out there!
There are a number of ways to upgrade. First, to clarify, you are technically not upgrading
. You will be doing a clean install. Check out this awesome tutorial
If you have an external hard drive or thumb drive bigger than 4GB, it would be safest to backup the ISO and exe files , in case anything happens.
What you can do is just run the setup.exe file. If you want to boot from a disc, you will need to burn the ISO to a DVD using ISO Recorder
or a similar program.
Hope this helps,
