[Answered] Multiple autounattend.xml

You can only have 1 autounattend.xml in the root of your install media (USB/optical).

If you boot your media, you can then SHIFT+F10 to open a CMD Prompt. From here you can run a custom batch file & do whatever.
ie, create partition, install using dism, etc..
Or you can run setup.exe & specify an unattend.xml:

Code:

Setup /unattend:UEFIunattend.xml
Setup /unattend:LEGACYunattend.xml
Setup /unattend:ADMINunattend.xml

Personally I use a WinPE that I created through Microsoft ADK & just run a batch file that let's be install any OS, any Index, include drivers, etc.

Copy everything from second unattend file except

Code:

<?xml version="1.0" encoding="utf-8"?>
<unattend xmlns="urn:schemas-microsoft-com:unattend">

and

Code:

</unattend>

to the first file above </unattend> line, then load the unattend in System Image Manager and remove duplicate entries.

 

1 applied directly to the image to handle OfflineServicing settings
1 added to the Panther directory to handle OOBE/Setup/Specialize
1 added to the installation media to handle WinPE/Disk creation, etc.
