First we need to create discover image.
- In the Windows Deployment Services MMC snap-in, expand the Boot images node.
- Right-click the image that you want to use as a discover image.
- Click Create Discover Boot Image.
- Follow the instructions in the wizard, and when it is completed, click Finish.
Now it’s time to create bootable media with this image. We need Windows Assessment and Deployment Kit (ADK). After downloading and installing WIndows ADK,
- Click Start, and type deployment. Right-click Deployment and Imaging Tools Environment and then select Run as administrator.
- Create a working copy of the Windows PE files. Specify either x86 or amd64:
copype amd64 C:\WinPE_amd64
- Copy the previously created discover image from WDS into
C:\WinPE_amd64\media\sources
as boot.wim and overwrite existing boot.wim.
- Create an ISO file containing the Windows PE files:
MakeWinPEMedia /ISO C:\WinPE_amd64 C:\WinPE_amd64\WinPE_amd64.iso
- Burn iso file to CD/DVD or USB.
