Setup Media Template

This folder is the base for the bootable ISO structure when using -UseSetupTemplate.

The maker scripts will:

1. Copy install.wim from the source ISO into sources/
2. Copy everything from this folder on top (merging into the scratch directory)
3. Mount and modify install.wim (bloat removal, registry tweaks, etc.)
4. Mount and modify sources/boot.wim (LabConfig bypasses, branding)
5. Run oscdimg on the scratch directory to produce the final ISO

Populate from a Windows ISO

Mount a Windows ISO and copy these files/folders here:

boot/
efi/
sources/boot.wim
bootmgr
bootmgr.efi
setup.exe
autorun.inf
etfsboot.com        (from sources/ or root)
efisys.bin          (from efi/microsoft/boot/)

Do NOT place install.wim or install.esd here — those always come from the source ISO.

Customisation

Files in this folder will overwrite the matching file from the source ISO. Typical customisations:

• sources/boot.wim — replace with a pre-themed WinPE (still gets LabConfig registry tweaks applied by the script)
• sources/background.bmp — custom setup background (also patched by branding-resources)
• boot/ / efi/ — custom bootloader files
