Thanks for the link Brycen. That solution worked but it also wiped out my WinPE 5.1 Pre-Boot Files. Since Windows 10 support is one of the new featues of GSS 3.1 I am a little suprised this GSS 3.0 work around is how WinPE 10 supported. I was hoping there was some switch or configuration edit needed to expose WinPE 10 in the Pre-Boot list.
Oh well maybe in HF 1 when it comes. GSS is still great though and even more so with development ramped back up.
