use a dell c600 latitude, when i try to open windows xp pro. service pack 1 i get the message windows could not start because the following file is missing or corrupt: \windows\system 32\config\system.. you can attempt to repair this file by starting windows setup using the original setup cd-rom select r at the first screnn to start repair. I have tried to reinstall and i keep getting the same message, any key i hit restarts the computer? has anyone had a problem like this and if so please tell me how to slove this step by step. how do you wipe out the harddrive and start all over? I can get to f2 setup and f8 but nothing works....need help, thanks
