If you take your time, dont panic and ask questions this will be easy. Read over this tutorial, tonight. Cheat, the way I did go to you tube and watch the clean install. It really is not hard. Just don't get nervous. I did a clean install and its really not a problem. The worst part is reinstalling the programs, but I did as needed and it was done quickly.. Clean Install with a Upgrade Windows 7 Version
My advice has now changed, since I found out about the upgrade. I am no longer suggesting that we rectify this problem, just do a clean install.
Want to be sure that it is the right course, post a new thread give the facts and have a title should I do a clean install. You will get many, many opinions. I will be glad to help whatever you decide, but my opinion will not change.
If you want to try and repair, follow the instructions that I gave you previously. To close the thread just click on the middle icon, upper right. Then type solved and managment will close it.
