I appreciate the good tutorial and helpful comments... My pc was built with Vista 64-bit Home Premium w/SP1. I have all of the discs used in the system install and also received a Windows 7 Upgrade Option Program DVD. I hope to do a clean install but have some questions...
Do I have to anything to my hard drive (for example uninstall any programs?) before proceeding with option 1? Since DVDs load automatically, when I reboot will the install automatically boot off the DVD? Please forgive me if these are silly questions!

Also, what do I do if I need to reinstall Windows 7 in the future? Must I first install my Vista or just insert the 7 upgrade DVD? Thanks for your gracious help!
