Thanks Steve for the reply.
I am still stuck on one part.
My surface pro 3 seems to load the \boot\boot_x64.wim fine from my PXE Representative (although it takes about 5 minutes). I get the following in Windows PE
x:\windows\system32>wpeinit
x:\windows\system32>wpeinit /unattend=x:\ldclient\setoptions.xml
x:\windows\system32>\ldclient\LDDrvLoad_x64.exe
The system cannot find the path specified.
x:\windows\system32>wpeutil disablefirewall
The command completed successfully
x:\windows\system32>reg import all.reg
The operation completed successfully.
