Note that the BIOS Boot Mode of the laptop must be set to Legacy in order to create a Windows MBR install.
My solution was to install a blank harddrive into the laptop, and install Windows 10 Pro onto it using a USB drive created with the Windows 10 Download Tool. Note that a GPT/UEFI install of Windows will not work. My recommendation is to use an MBR install of Windows 10 rather than the fancy Windows PE method. HP has a WinPE64-2.10 tool that automates this process, but I failed to replicate it with the Windows ADK. I struggled with this for many hours, and while I could create the bootable Windows PE (v10, v8, & v2.1) USBs, I could never successfully run the Wndmifit64.exe application in that environment.
Gather necessary files by googling nbdmifit-2.03.zip (which are the HP dmi fit tools), from the Chinese site.
Gather your laptop info: Serial (below battery), SKU (product number), PCID (remove back panel) and System Board CT (look through the holes in the metal plate, its 14 digits from the left to right on a white label). So, as a last resort and without breaking any copyright laws, I used wndmifit64.exe from HP. If the laptop were under warranty fine, I would have gone to HP directly, but that was not the case.
