Problems getting comp to boot from cd

[Reckoning]

I booted a comp from an XP Pro cd last week so I know the drive works. I've decided to instead go with an Xp Home install so that I can use the cd key stamped on the tower.
I burned an .iso of XP Home and tried it in another computer and it works fine (so the cd is burned correctly) yet I put it in the other computer and I can't get it to boot from the cd. I've changed the boot sequence in BIOS and it still won't give me the option "Press any key to boot from cd..." Instead it says "strike f1 to try again, or f2 to enter setup"

Swap the CD drive with the one that drive that the disc worked in and try again. Burned CD's can sometimes fail in one CD drive and work perfectly in another. The burn speed can often cause a problem, you should burn ISO's at 4X or less as this is far less inclined to produce errors.
