How to Prepare Setup Answer File for Specific OS Image

You can prepare the setup answer file for specific OS image using the following process:

Each OS image has a RIS setup answer file which can be located in the following path on RIS server:
```
Drive:\RemoteInstall\Setup\Language\Images\ImageName\I386\template\ristndrd.sif
```
The RIS setup answer file is in .ini format. For more information on the RIS setup answer files, see the Windows deploy document. By default, this file is configured for normal setup. You must change it to support Windows ASR mode.
You must configure the RIS setup answer file for each OS image only once. Open the RIS setup answer file. In the [OSChooser] session, modify the key values:
Change the following key-value pair:
```
ImageType= Flat
```
to
```
ImageType = ASR
```
Add the following key-value pairs:
```
ASRFile=asrpnpfiles\%guid%.sif
```
```
ASRINFFile=\Device\LanmanRedirector\%SERVERNAME%\RemInst\ASRFiles\%guid%.sif
```
Note: The guid parameter is the computer UUID which is stored in computer BIOS. To know the UUID, launch remote install on the client machine which is being recovered and go through the OS chooser screens. A .sif file is generated in the Drive:\RemoteInstall\temp folder on the RIS server. The file name of this file is the UUID of the client machine.

The RemInst value in the ASRINFFile must have the same name as RemoteInstall directory. The RemInst is the default share name created by RIS setup.
Create the following directories in the Drive:\RemoteInstall\ folder:
- ASR Files
- ASRPN Files
