Reset after upgrade

I have a pc here that was originally win 7, then upgraded to win 8 (not 8.1). I wish to reset win 8 back to it's newest condition. I did create a recovery drive. Can I simply follow the 'Remove everything and reinstall windows' feature, or will I need to use the drive I created? I don't want reverting back to win 7 or cause an issue because win 7 was on it before. Clarification please?

Did you download the ISO?
