Visual Studio 11 Beta uninstall

My question is how to get my system to a state to reinstall VS 2010 .
Recently I installed the beta version of VS 11 along side VS 2010 and SQl server 2012(yes i had 2012 sql server running and working prior to installation of VS 11) after using it for a little while I wanted to remove the program(.net 4.5 beta caused conflicts with other programs running on the system). Well now the my installation of VS 2010 has been corrupted. I completely removed beta version and .net 4.5 beta. Removed VS 2010 and .net 4 . Reinstalled VS 2010 and .net 4 installed updates reapplied VS 10 Service Pack 1 and got it to an operable state but there are certain things that I can't do like create entity models.

Have you restarted the machine, what errors you get when to try to build entity model using your VS2010

This error is just the first so far.... I know that there are more to come and in the back of my mind I know there is a Windows 7 reinstall involved.

This is a perfect time to suggest what I and others do when it comes to beta versions along side other versions--use a virtual disk.  Creating a virtual disk is pretty easy, since applications like Virtual PC and VirtualBox are free.

With that said, it would be best to contact Microsoft, and let them know about your experiences with installing the 4.5 alongside 4.0, and hopefully they have an uninstall guide.
