Laptop with Windows XP Media Center edition won't boot.
User got the Moneypack virus. It is a scam where the computer screen is taken over by a warning that the computer has been locked by the FBI and you have to pay a fine of $300. The user didn't pay the fine or believe any of the nonsense but when he tried to reboot into safe mode the computer now will not boot to a desktop.
tried best known good config, safe mode, safe mode with networking, start windows normally but all of them start to go to the Windows loading screen but then cycle back to the screen that gives you the choices of safe mode etc.
What is the best way of repairing this so it will boot without having to reinstall the operating system and all the programs.
