System becoming unstable (i.e. frequently refusing to start) I want to reinstall the OS. (Yep I've got good backup!) WinXP was preinstalled by manufacturer. Booting from the OEM recovery disk I get the message: 'OS is older than the one installed. Cannot continue.' Does this mean I have to uninstall SP2 before booting from the recovery disk?
If so, and WinXP will not start . . . it's Catch22!
