# 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

## Usage

```powershell
.\tiny11maker.ps1 -UseSetupTemplate
.\tiny10maker.ps1 -UseSetupTemplate -windowsisopath D:
.\TinyWindowsMaker.ps1 -UseSetupTemplate -windowsisopath "C:\path\to\windows.iso"
