Ray, why do you want to install Windows 7 which is the future? Maybe we can help you work out any issues as most of us have been beta testers for more than a year and have likely already dealt with the issue(s).

But if you want to know for sure you are uninstalling without any effect on the other OS, please post back a screenshot of your Windows 7 Disk Management drive map and listings, using Snipping Tool in Start Menu and attaching file using paper clip in reply box. Label what is where and tell us exactly what you want.
We can then give you the exact steps.
