Handy Guide for Windows 7 Deployment using MDT 2010
I have had quite a journey with Windows 7 Deployment in the last couple of months. I've had major issues, broken images, capturing problems, you name it. I have however come through it very satisfied that I can now Create and deploy Windows 7 images with injected drivers, hot fixes with only the odd issue cropping up.
I was shown this guide when I first got started, I don't know if it's been linked to on here but here it is anyway. If you are having problems with Windows 7 deployment I strongly recommend you have a look through, I've found it extremely helpful! Some parts lack bits of detail but it's a good place to start.
Deploying Windows 7
N.B - It's a 23 odd part article but is split into logical sections to make it easier to find what you're looking for.
I also found the following three guides helpful when I couldn't connect to my deployment share. (It turns out the latest Broadcom network drivers were not included in the original boot image so I had to inject them "manually")
Mount a WIM image using DISM
Add or Remove Drivers using DISM
Unmount and Clean up a WIM image using DISM
Again, sorry if these guides have already been mentioned.
