Your best bet might be to use the link near the top of your email receipt from MS to start the process over, but instead of doing the Upgrade, when you have the choice choose Install by creating media, then choose Custom install.
This allows you to burn the ISO file to a DVD or Flash drive and use this to boot to. Choose Save Nothing and Custom, or whatever.
Install the OS and all your apps again. Then change your pointers in the OS to the data partition (drive) using the
approved method.
The installation should not affect your data partition (drive) what so ever. This is the exact method I used and our 2 laptops (conventional non-touch 4 to 5 years old) work perfectly.
I realize this involves more work, but how much time have you lost so far. It took me 5 hours total to install my OS, customize my OS, install all my apps including Office 2010, update everything, and create 3 separate Images, one after the OS was installed and customized, the second after apps installed, the third after Office was installed and everything was completed. 5 hours total!
I save all my Images to my Ext. HD and use it for
File History. I create new Images at least once per month after patch Tuesday.
I suppose you could try a System Refresh, but this will also uninstall all the apps you installed and is a fairly slow process, and has had a few mixed results. That's why I advocate the Custom Install every time. The Upgrade depends too much on the original OS.
