The ISO burning function just burns whatever is in the ISO image to the disc; it doesn’t process the data contained in the image before writing it (hence, a corrupt image will result in a bad disc; Windows will not warn you or correct it before writing). Bootable images contain the boot-record (usually as floppy image) in the .iso file. So as long as the image contains the boot image, then the resulting disc should be bootable.
The burn-to-disc function (which has been available since XP) does not support bootable discs because it works on a file basis. You specify files to be burned, Windows copies them to a holding directory, then when you select the write these files to disc command, it compiles an image and burns that.
(Interestingly, even Microsoft’s own MVPs don’t realize that this is possible. I concur with JoelbX and avirk; ImgBurn is a great—and free—program to burn both images and loose files/folders—without even having to first compiling an image! It has an easy to use interface, but also provides numerous configuration options for complete control.)
