I haven't seriously debugged with the Windows 8 loader, but did do some
work with Server 2008 (aka Windows 7, I believe.) The basic approach
may be the same.
There's often debug output from the boot loader (bootx64.efi) which you
can turn on with command line switches. Try using the "/h" or "-h"
switch to get a list, or searching Microsoft's web site. You may need
to run the boot loader from the EFI shell to do this.
I think you may be able to press some special key at the "Press any key
to continue..." prompt (F2? F10?) to get a menu of boot/debug options as
well. I forget the details, though... Again, Microsoft's documentation
would be where to look.
Did you try a different DVD drive, or a different DVD? Maybe it's just
bad h/w or media. It's possible to transfer the image to a USB flash
drive and install from there as well.
It's also possible to debug the loader using windbg, Microsoft's
debugger, via a serial port or USB debug cable. There should be details
on their web site. It should be able to fetch Microsoft's symbol files
for the loader (you may need to use a "checked build" of the loader?)
You won't have source code, but you may be able to get a clue as to
what's going on by looking at function names.
You can also turn on additional debugging in your UEFI firmware, to see
if an EFI service callback or driver is causing the hang. Or you can
add specific DEBUG() output at suspicious places, if you're building it
yourself. I find it easier to connect via a serial console rather than
VGA, so I can log output to a file and search it later for interesting
pieces.
If you're using Intel's BIOS, you could always ask their tech support
for help...
A few ideas. Hope that helps.
