Hello,
This is a brand new out of box Dell XPS 7390. I can PXE boot and start the SD process but as soon as it tries to grab the Windows 10 WIM I get "The target computer does not contain a corresponding disk" error. I went through the setup process and noticed there's a few partitions under disk management. I see on the 7390 there's a dedicated Image partition set to approx 12 gigs. I don't know if that would be causing SD to not be able to complete the deployment process.
