I have a dell T3400 workstation that was virused out. Adware 'Cyber Security'. We have attempted to run the XP pro SP2 reinstallation disk (Dell), but it would not run windows as 'virus or hardware problem. C;\Windows was subsequently removed to work around this, but now the reinstallation disk cannot find enough of the original windows to run. The machine does not have a floppy. How can i run my reinstallation disk / format and get windows reinstalled. Thank you.
