the command to run the installation is: setup.exe
Just be sure the installation CD is inserted when you type it. When you press enter, it will scan your hard drive for error before starting the installation....just let it run and when the scan is done, just press "exit" and it will go into the installation..
But you may have problems installing it without formatting the drive first..
If I were you I would type: format c: first, press enter and let it format the drive..
Try starting the installation without formatting and see what happens
