Help Plz!!!!!!!!!

ARGH!!!!!!! I finally got my nrew motherboard which is a delta-l nforce from MSIthat I bought on Ebay . I have duel operating systems on it and i had to unplug one drive so i poped in the windows disc and it said that it was intalizing drivers then it aked me if i would like to repair or reinstall i cant reinstall cause i dont have a windows cd. Then i pushed enter for repair and it came up as this black command and said somethhing and i did wat it said then before it fixes it IT COMES UP WITH A ADMINISTOR PASSWORD AND I TRIED ALL THE PASSWORDS I NO BUT IT DOSNT WORK! AND I WANT TO PLAY SOME VID GAMES

Instead of using the first repair, tell it ur going to do a new install and it will search for previous OS's and ask again if you want to repair. That is the one you want but make sure you have your key.
