We got four new XPS 15s in for testing and I gave one, then a second, to a guy on our server team. He managed to brick two of the four XPSes when trying to enable Hyper-V. After the fact I found this article that references WIndows 8.1 plus Hyper-V plus DDPE is unsupported and may crash the system. https://www.dell.com/support/article/us/en/rc958177/sln294086/running-hyper-v-on-a-windows-81-machine-with-dell-data-protection-encryption-installed?lang=en 

Is Hyper-V still unsupported in WIndows 10 with DDPE enabled? I found an article advising to white list three Hyper-V related sources on Server 2012 R2, but would that also work for Win10?

Also, I have tried reimaging these two bricked units with our own Win10 image, with the Dell OEM Restore image, and with a Win10 USB installer drive and all methods fail on "applying UEFI partition". We don't care about the data on the SSD so is there a way to get these machines working again without replacing the SSDs?

Thanks!
