let me guess, you selected the "remove boot from cd prompt" after the files have copied (blue screen) and the pc has rebooted once, eject the cd, when it asks for it again, put it back in, then eject it after its finished all the windows install.. in future don't select the select boot from cd prompt option... or after its started installation once, change your boot order so it doesn't look for the cd int he fisrt place/
