NOTE: I have setup a blog that is just for tech related stuff, if you like this post, there are more tech posts here: http://animusprime.blogspot.com/
This post should give you the basics in how to build a Windows 7 image that contains drivers for many different models. Image creation can be fairly straight forward or it can be very involved depending on how much you want to customize it.
What you will need:
- Windows 7 Installation CD / DVD
- WAIK installed on your computer
- A computer to build the image on (if you have VMWare or a HyperV server that would be better)
- A USB flash drive large enough to hold your image and WinPE (8 gig drive is OK if your image is pretty thin, 16 gig drive should do it unless your image is really big)
