I spent a while experimenting with a proper way to clone a drive on a few Windows 8 machines that were configured to boot off UEFI. So far, exactly none of them have worked 100% properly.
The most likely error I seem to run in to is an error in the Windows startup files on the System partition, evidenced as a c0000225 BSOD on startup, which is fixed by the following:
Boot off Windows 8 install media
Get to a command Prompt
diskpart
list disk
select disk X (the one with your boot files)
list partition
select partition Y (the very small one labelled SYSTEM)
assign letter=Z
exit
BCDBoot c:\windows /s z: /f UEFI
Then re-set the firmware to boot in UEFI mode and you're probably good to go.
