Hey thanks for this. Worked like a charm on my 5970. I'd like to be able to automate more stuff though. Is there a way to alter the wim file? Never done this before and (apart from mining) there are great possibilities regarding such a usb based thing (Tor implementation, wallet intergration etc).
I've been messing with this myself, trying to make a build that has remote access and some other features I'd like. I'm still new to PE stuff so don't shoot me if this doesn't work out, but if you want to alter the OP's build:
1. Download/install Windows
ADK http://www.microsoft.com/en-us/download/details.aspx?id=306522. Extract OP's ISO to a folder on your C drive(root) drive. (I'll call it C:\CraPE)
3. Make a new folder in your C: drive (I'll call it C:\mount
4. Open Deployment and Imaging Tools Environment as an Administrator. Run this command:
imagex /mount C:\Crape\sources\boot.wim 1 C:\mount
Everything that is in the OP's boot.wim should now be available to edit in your folder c:\mount. To save:
imagex /unmount c:\winpe_x86\mount /commit
I actually haven't been using the Windows ADK directly, I've been using a program called Winbuilder to work on a build from scratch. There's a forum
http://reboot.pro/) built around Winbuilder where people share their custom scripts and stuff, also Winbuilder has a feature built in that lets you download different projects and scripts from different servers.
This guy's guide and downloads gets you a fresh Win8 x68 iso plus winbuilder with some basic building scripts:
