while captureing image i am not sure what could be the difference between 2 methods. which one is right a) exacting iso image & creating package in operating system install package - capture in the images on unkown machine (with out OS) b)exacting iso image & creating package in operating system install package - capture in the images on kown machine (Windows 7 installed machine) if any difference & what is advantage / disadvantages both of methods

your question doesnt make much sense so i'll link you to a guide i wrote which explains from start to finish how to Build and Capture Windows 7 Enterprise, http://www.windows-noob.com/forums/index.php?/topic/1182-deploy-windows-7-enterprise/ when creating your build and capture image use Virtual hardware (vmware, hyperv, virtual pc 2007 sp1, etc etc) cheers niall Step by Step ConfigMgr 2007 Guides | Step by Step ConfigMgr 2012 Guides | I'm on Twitter > ncbrady

You can choose between a "Build and Capture" task sequence (which is recommended) and ConfigMgr Capture media.
