Q: Boot Camp W10 pro stuck in "Critical_Stop_Error" reboot cycle

The Error is "CRITICAL_PROCESS_DIED" I'll attempt to edit post

I removed the Windows Partition using BCA. I reset the SMC and NVRAM with everything removed except my mouse. I connected the USB Installer ran BCA chose the last option. Windows installed and Windows asked for key code. I entered the key code and the installation complted. Upon first reboot I get the same error:

STOP CODE: CRITICAL_PROCESS_DIED

It came directly from the exact Microsoft link you listed. I am running the English only ISO. This was supplied (the link) upon purchase of the OS. I will go ahead and give everything a GO again.

I have in fact already done the exact thing you have instructed. I completely re-formated the USB flash drive and built the installer using the BCA tool. The ISO has been saved to my desktop, and also I have tried it from the downloads folder. The ISO of course was linked to the tool as instructed.

Give me about 30 and I will report back.

yes.  Here is the ISO version:

WIN10_1607_English_x64.iso

So, i'm getting the exact same result here. Critical Stop: Critical_Process_Died and endless reboots.

I will try and find a 2.0 USB that is larger than 4gb.

Ok  here you go.

Suggesting that  I make the Windows partition larger than 1TB?

I found a 2.0 USB I am creating the tool with it now.

Another Update.

I split the Drive evenly this time.  1.5 TB / 1.5 TB Same Error.

I created a USB 2.0 version of the tool. Same Error

Of course completely starting from scratch each time SCM, NVRAM resets BCA used to completely re-create the tool and partition the drive.
