We've purchased a Compaq Presario CQ60 Notebook PC from a local Wal-Mart a few years ago. Upon our first boot, we were asked to create recovery discs of Windows Vista because the manufacturer did not provide installation discs.
Recently, Xubuntu was installed and corrupted the system (post here). Our only option to remove it completely is to make a factory reset from the recovery discs. Since the discs were created a few years ago, a massive amount of updates showed up. On our first attempt to do all of those updates at once, the result was a warning from Windows saying that our Windows Vista OS was counterfeit. We know that we don't have a counterfeit OS because we have a Genuine Windows Vista Home Basic Certificate of Authenticity. What should we do and how do we prevent this problem from occurring again?
