You should be able to use both, however apparently there can be problems. I saw some information here
that might be helpful. Let me know if you get it to work. Scott.
Thanks the first link was very helpful, although I didn't actually read it correctly at first! You have to include the path to the .wim file as the poster outlines, in the Microsoft-Windows-Setup\ImageInstall\OSImage\InstallFrom section of the answer file. But, and this isn't made clear in the documentation
, you have to use the relative path like so \install.wim. The Windows System Manager is pretty useful once you become comfortable using it, I think they could have made it a bit more user friendly though! One of the features I've found handy is the ability to run scripts at the first log in. So you can install a product key and automatically authenticate windows (you obviously need to be connected to the network) by running these as two separate commands:
cscript //b c:\windows\system32\slmgr.vbs /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX (where X is your Windows key)
cscript //b c:\windows\system32\slmgr.vbs /ato
And set the firewall and powercfg options by using a couple of commend line options.
