How to determine why a burned DVD won't boot?

So I have an interesting problem where a burned DVD of "debian-7.2.0-ia64-CD-1.iso" won't boot.

The DVD is a DVD+RW. I have tried erasing, burning, and booting from "debian-live-7.0.0-i386-gnome-desktop+nonfree.iso" and that works fine, but I would rather install debian 7.2 with the x86-64 architecture.

After burning "debian-7.2.0-ia64-CD-1.sio", I can mount the CD as well and it appears that all the files show up correctly.

I was just wondering if there is any sort of boot sector I can try inspecting on the ISO to see if perhaps it is incorrect.

Thanks!

Best guess (since you seem to have used the same disc and reader for the successful boot) would be that your hardware may not be 64-bit capable. Try booting it (not installing, just booting) on another machine, and/or booting a different 64-bit LiveCD on this one. – Ecnerwal – 2013-11-10T03:03:45.747

"ia64" is for the Itanium CPU architecture -- it's not the x86-64 image you say you're looking for.

The x86-64 images are marked as "amd64". Here's a direct link for ya: http://cdimage.debian.org/debian-cd/7.2.0/amd64/iso-dvd/

Additionally, if interested, perhaps check out this info regarding booting to the Debian IA64 disk image - apparently they've had trouble with it in the past (and perhaps currently as well) when it's used on a system with a EFI.

DVDs don't have boot sectors, and as far as I know don't even have flags that you might find on a normal HDD or pendrive. Check your boot order and that the syslinux, which I believe debian uses for live CDs, is present and configured correctly. Try testing out the iso(Or the actual CD) using VMWare, Virtualbox, or QEMU, to make sure it works.
