Hi Brute Force,
After reading through your Malware Forum thread, and this thread again, it's obvious that you are unable to continue until you obtain an original Microsoft Windows XP disc.
Why do you have a Corporate Edition of Windows XP? Is this a work computer? If so, the IT Administrator from your work should have the original disc for you to access? If it's not a work computer, then I question whether or not you should have the Corporate Edition installed at all. The XP Corporate Edition was known for its installation that did not require a COA Product Code input to install, and became popular on P2P for people trying to get a "free" (i.e. stolen, illegit) version of Windows.
If your version is not legitimate, then we cannot help you here as it is against the
Terms of Use, to which you agreed when you joined this site.
If you aren't sure at all, then feel free to visit the
Microsoft website to double-check that your version installed is, in fact, legit. You'll still need to track down an original disc (all fancy looking with Microsoft holograms etc) for the repair. Any retail disc will have it, along with the official Microsoft OEM disc. Any other OEM (i.e. from Dell, Acer, and the like) will be manufactured to include their own recovery console, and will not have the repair function available.
Cheers
Troy
