The install should go without any problems on a physical UEFI machine. Tho if you install the hotfix and check your WDS service, you can go ahead and build gen2 VM's in Hyper-V without any problem, as matter of fact that is what currently is happening on my machine as I'm typing up this post. Testing the tasksequences on a hyper-v gen 2 machine to catch the problems, then deploy it for the physical machines.
But why would you actually go ahead trough the trouble of capturing and sysprepping when your using SCCM?
