Can someone help me?

I decided to do this all over again. so i downloaded the Windows Vista 32-bit recovery disk torrent. So its finished downloading. and i'm not to sure on what to do after it finishes downloading in uTorrent. it says to save it using imgburn. the first time i did it, it burned to a CD but nothing happened when i put the cd in. Can anyone give some helpful steps on what to do when its done downloading...please.

Access the CD from My Computer (Start > My Computer). If you have just a single file, it did not burn properly. Otherwise, the disc is fine, you just need to reboot your computer and boot from the CD (it doesn't run within Windows).
