A bootable ISO is created from an existing WDS boot image and capture image that contains Windows PE and the WDS client can be stored on DVD or CD making it easier to deploy images to older systems or on heterogeneous networks that have PXE issues. To accomplish discover image process, you must have a working WDS in network and Windows 7 AIK installed in WDS server. Log on to WDS server using domain admin credential and follow the screen shots.
Create a folder in e:\DiscoverBootImage or whatever drive you have and provide FQDN of WDS
Now you have e:\DiscoverBootImage\WDSDiscover.WIM . Open Start menu>Microsoft Windows AIK>Deployment Tools Command Prompt>Type CopyPe x86 E:\DiscoverBootImage\Winpe and wait for completion
In the same command prompt type
Copy /y E:\DiscoverBootImage\WDSDiscover.WIM
E:\DiscoverBootImage\WinPE\ISO\Sources\Boot.wim
To write WIM file to ISO type following
oscdimg –n –bE:\DiscoverBootImage\Winpe\ISO\Boot\etfsboot.com
E:\DiscoverBootImage\Winpe\ISO E:\DiscoverBootImage\boot.ISO
Now you have created ISO boot image. Burn this ISO on a CD or DVD and boot client machine using this cd and deploy images.
