I am attempting to Load a fresh copy of Windows on a Dell Dimension 2400 machine. The installation process is extreamly slow and has taken hours to get to even the 50% mark. I also get an error when I boot the machine that states the following " Primary drive 1 not found strike the F1 key to continue, F2 to run the setup utility" . I have changed the ram in the machine with a new stick and tried 2 other new hard drives in the machine all with the same results. SLOW TO INSTALL! I have also tried a different windows CD which installed fine on another computer.
