I think I bet against this recovery ending anytime soon, so here is my advise in case it goes wrong:
If you have important files inside your computer, and they have not been deleted by this "recovery" attempt, you can use an Ubuntu Live CD to try to rescue those files: http://www.howtogeek.com/howto.....-computer/
You can download the ISO image of Ubuntu Live CD from http://www.ubuntu.com/download/desktop . Select 12.04 (32-bit version), and then on the next page go to the bottom and select "Not now, take me to the download".
Then you should do a clean install of an Operating System. But I don't know how you could legally obtain a Windows XP Media Center installation disk. If you don't have one we'll try to find a way you could get one.
Also, please take into consideration that Windows XP is 11 years old, and support for it ends in April 8, 2014 (that's in 1 year, 4 months and 23 days). Consider upgrading to a newer Operating System, such as Windows 7 or Ubuntu 12.04. If you want, you can download an ISO for a Windows 7 install disk and try it in your computer without a key for 30 days: http://www.askvg.com/direct-do.....nd-64-bit/ . Ubuntu is free, and you can install it from the Live CD i mentioned above.
