Installation
Due to a bug with the  file, the system may trigger a   bug check when booting to Windows Setup. It can be bypassed by debugging the file with Windows Debuggers during the installation process.

Detailed instructions:
 * A: Extract the BCD file from the installation media (located in  for legacy BIOS boot, or in   for UEFI boot) and put the file into any folders.
 * B: Open Command Prompt with elevated privileges and execute the following commands:


 * C: Overwrite the original BCD file in the installation media with the modified one.
 * D: (Skip this step on the real machine) Set up the serial port for the virtual machine.
 * For VMware Workstation on Windows host: Add a seiral port via the "Add..." button, change the connection type to "Use named pipe", enter the pipe's name (Format:, e.g.  ), then choose "This end is the Server, The other end is an application".
 * For VirtualBox on Windows host: Check "Enable Serial Port" in the "Serial Ports" section, select "Host Pipe", uncheck "Connect to existing pipe/socket", and enter the pipe's name (Format: ).
 * For Hyper-V: execute the following commands in PowerShell:


 * E: Install Windows Debuggers from the SDK (Windows Debuggers Preview in the Microsoft Store won't work).
 * F: Open Command Prompt, locate the path where Windows Debuggers is installed (for example in ), and execute the following command:


 * G: Boot the machine from the patched installation media.
 * H: When "We are running at normal mode" displays in debugger's command output, press Ctrl or select Break in the Debug menu to stop the boot process, then execute the following commands:


 * I: When  hits a breakpoint, execute the following commands:


 * J: Install the system as normal and shutdown the machine before Windows Setup is attempting to reboot the system.
 * K: Repeat steps A and B for the BCD file on the system partition before turning on the machine again.
 * Repeat steps F, H, and I before booting into "Getting ready" screen/out of box experience, and whenever the system is being rebooted.

Alternatively, replacing  and its corresponding catalog file can also bypass the bug.
