No difference.  If it runs the format and partition disk UEFI step, it creates 
another entry.

Not sure what should clean up this, if W8.x has to figure out there is already 
one or CM.
In any case it is annoying and with Hyper-V it breaks the entry :(

Refresh or new install all the time?
Is there a difference for you?

I've noticed in testing on live machines that it makes boot entry after boot 
entry when I run the image process over and over.  Only way to get rid of them 
is to go into the BIOS and toss them.

I think there is an issue with Gen 2 VMs with UEFI on Hyper-V (Win 8.1).

A new VM might have those entries for boot:

A new deployment of 8.1 to such a system creates a new entry in that list and 
works fine:

But when that VM is re-installed, every new installation creates an additional 
"file" entry.

Another issue with UEFI:

When such a system is refreshed, it installs without a problem, but then 
Hyper-V says the boot data is broken:

Deleting that entry fixes it:

Firmware Application (101fffff)

identifier              {65c5ef67-bf05-11e3-bcc1-00155d010832}
device                  partition=\Device\HarddiskVolume2
path                    \EFI\Microsoft\Boot\bootmgfw.efi
description             Windows Boot Manager

Anyone else seeing any of those?
