Do you have any other bootable media to try? If not, try downloading Ultimate Boot CD - v4.1.1 ISO from here, burn it, and see if it boots.

You seemed to have burned everything correctly. You can use IMGBurn and just straight burn the .IMG or you can try renaming the .IMG to a .BIN and the .CCD as a .CUE and open up the .CUE with Nero/IMGBurn/whatever it is you use.
