After installing the unofficial windows 98 service pack, i encountered a huge problem. Every time i restart my computer, Microsoft Registry Checker appears and says "backing up system files". It will continue to say that it was successful and that I should restart my computer. After restarting the computer, the exact same thing happens where the Microsoft Registy Checker opens. I cannot get to windows so I don't know what to do. Is it possible to uninstall the service pack from MS-DOS, or is there anything else I can do? Any help will be greatly appreciated. TIA
