Will try to explain this as best as I can. We currently do this with an XP based build we use. We currently copy a couple boot files and a bootable ISO to a machine, reboot that machine and have it load into a WinPE RAM setup and use some custom script to reimage the machine. We want to replicate this setup in a vista enviornment, which looks like I need to tweak BCDEdit and use a wim instead of an ISO. What I want to know is if anyone knows how to use BCDEdit to just replace the default boot device with an existing WIM image. I have found many articles that talk about adding a menu item to the boot menu to get this effect, but this requires a unquie GUID on each machine setup, hoping there is a general way to say to the machine "Boot from this WIM next time, regardless of anything else" So the idea is I could copy a wim file to the local machine, run a script to modify BCDEdit, reboot the machine in a PE environment. Any ideas? Thanks again.
