@bareimage Well I’m still not 100% clear on the provisioning process, TBH that is something new with windows 10 and many people are still stuck in the methods for deploy operating systems from the past. So they try to force windows 10 into something they know. We all will need to understand provisioning packages because that is the direction microsoft will go with all future operating systems.
As I see it you could go about this in 2 ways.
(non-fog) Use an application deployment tool like PDQ Deploy to drop the provisioning package in the proper location on the target computer and then force a reboot. This can be done remotely and all hands off. You are just placing the file in the right location and then letting windows find it on startup. What ever magic happens inside the provisioning package is done there. There is no need to pxe boot or even need fog in this situation.
Use FOG to deploy (push) the (thick or thing) image to the target computer. Once the image is pushed to the computer, then FOG can drop the provisioning package in the proper location then reboot the computer. The target computer would then run through OOBE as it normally would. At the end of OOBE it assume it would see the provisioning package and then it would do its magic. FOG can load a 15GB thick image to a bare metal computer in about 4 minutes for a typical install. In my work infrastructure I can push that same 15GB image in just over one minute.
Option 1 would take less internal resources since you are only dropping the provisioning package onto the target hardware. The issue you have is how will you get windows onto the bare metal to begin with? If you are using OEM versions of windows, then the target system should be loaded from the manufacturer. The risks are if the system hard drive fails you will have to manually reload widows from OEM media.
Option 2 take more internal resources to setup, but you can then have a system to go from bare metal to fully provisioning system using the lite touch process of imaging.
