Unable to autounattend Server 2012 RC

[Rapzid]

I seem to be unable to get an unattended install off the ground with the Server 2012 RC. It pops up the windows to select the image but says "No images are availabe". Which is bull, because I can do a manual install just fine and further back in setupact.log it reports it found 4 sub images. Here is my XML:

I'm using '/IMAGE/NAME' here, but I've also tried '/IMAGE/INDEX' do no avail. I've got the autounattend.xml on separate removable media, but have also tried packing it in the ISO with the same results:/ Using same process with Server 2008 no problems. Anyone having this issue?

Don't use it. If you are specifying the Install Key (which you are in the UserData object), then you don't need to use the InstallFrom object.

I have removed the InstallFrom block and it still pops up the window saying there are no images available..

Figured it out. I was using the Essentials key and not the Standard key. There was probably a clue in setupact.log as it constrains the image search and finds nothing. Thanks for your reply because it made me aware that Windows could actually choose the image based on the key itself:)

Yep! Its been that way since Vista at least. Makes creating answer files a whole lot easier!
