Welcome to the Seven Forums.
So where is the recovery disk?
If you haven't got one or have not made it then do you at least have the Product Key? If you have then please download an ISO image of your version of Windows 7 from http://www.mydigitallife.info/offici...digital-river/
. Please make a Windows 7 Installation DVD from it and use it either for recovering or clean re-installing Windows 7 using your original Product Key.
Please make sure that you download the version you were using and not some other version, otherwise this procedure shall not work.
