XP Pro install cancel?

I just installed xp pro on my new business computer. I have 2 hard drives. Everything went well , runs great. I put in the second hard drive and was going to install xp on it also. I ran the disc and realized it was going on my first drive so I cancelled it. Now when ever I start up it goes to a screen that asks me if i want to run xp or run the unfinished install. When I choose xp everything is fine however if I don't hit the run xp tab it goes to an install and even though I hit F3 to cancel it still comes back the next time for my choice. Do I have to live with this or is there a way to fix it. Thank you

u could reformat and install Windows again.

I was trying to avoid doing that. Is this going to hurt anything if I just leave it?
