Want to boot from windows XP Cd…won’t. Stuck on Verifying DMI Pool Data

I am not very computer savvy so please try to dumb down your posts. 🙂

My brother just gave me his old gaming computer. All I had to do was put my hard drive in it from my old computer. I put in my Windows XP CD because i need to install it and told BIOS to boot from it (1st priority) but it isn’t. It goes to the ‘Verifying DMI Pool Data’ screen and stays on that screen.

I have no idea what to do now. Thanks.
