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?
