Hi,

How to resolve it on Server 2025?

User's image

What is the same command for the above, when the server was started into command prompt mode?

    The command in your screenshot is wpeinit, which is a Windows PE (WinPE) command, not a normal Windows Server command. If Server 2025 has been booted into WinPE/command-prompt mode, the equivalent is:

    X:\Windows\System32\wpeinit.exe -unattend:"C:\Unattended-PE.xml"

    You can first verify that the executable exists:

    dir X:\Windows\System32\wpeinit.exe

    If it exists but wpeinit by itself says "not recognized", use the full path shown above. Also make sure the XML is actually on the drive you reference. For example, if the file is on the installation USB mounted as D:, use:

    X:\Windows\System32\wpeinit.exe -unattend:"D:\Unattended-PE.xml"

    Server 2025 Server Core's normal command prompt is not WinPE. If you are at a Server Core C:\Windows\System32> prompt after Windows Server has booted, wpeinit is not expected to exist, and there is no Server Core equivalent of wpeinit -unattend. In that situation, if your objective is to apply an unattended answer file during Windows Setup, you would normally launch Setup with the answer file instead:

    setup.exe /unattend:"D:\Unattended-PE.xml"

    In WinPE, the correct command is Wpeinit.exe or wpeinit, and it is normally started automatically by Startnet.cmd.

    If WinPE starts in command prompt mode, use:

    wpeinit

    Or, if needed, run it with the full executable name:

    Wpeinit.exe

    If an unattend file is required, use:

    Wpeinit -unattend:"C:\Unattend-PE.xml"

    Key points:

    1. Startnet.cmd is the default startup script in WinPE and it starts Wpeinit.exe.
    2. Wpeinit.exe installs Plug and Play devices, processes Unattend.xml settings, and loads network resources.
    3. Wpeinit writes log output to C:\Windows\system32\wpeinit.log.
    4. If WinPE was booted in a way that bypassed normal initialization, Wpeinit.exe may need to be started manually.

    If the command is being run on full Windows Server 2025 instead of WinPE, the context only confirms Wpeinit.exe as a WinPE component and startup command.
