Trying to do a repair install of xp

I have been trying to do a repair install of windows xp. After I hit the “R” key, it asked me for the admin password so I had to research how to set that. I went into safe mode to set the password. Now, when I enter the password I get the prompt C:\Windows. What am I suppossed to enter afer the prompt to get to the option to do a repair install? THanks
