Windows 7 unattended/silent installation EULA problem

I am a Cisco CCNA and networking is my thing.
However, I am often asked to provide Desktop Support for one of our Bluechip clients.
I have decided to study for the MCTS 70-680 Exam.
I'm very familiar with Windows 7 CD/USB installations, but I obviously need to be able to perform silent/unattended installations for the exam.
I want to go on to be able to do fully unattended installations via PXE and WDS.
I am self learning via a Microsoft Tutorials and using the web to expand my knowledge.

This is what I have done:
I have installed the WAIK
I downloaded an ISO copy of Windows 7 from Microsoft.
I created a bootable Windows 7 UFD and copied install.wim from the sources directory to mydocs
I selected the install.wim as my Windows image
I then opened the unattend_sample.xml file from Program Files\Windows AIK\Samples
I did some basic editing - changed language, added user details etc, nothing too fancy, just want to get a basic unattended installation.
Then I saved the answer file as autounattend.xml and copied this to a UFD.
I placed the Windows 7 bootable UFD and autounattend.xml UFD in a PC and tried to build it.
During the installation, I keep getting the EULA before it partitions and copies the installation file.

I have set the x86_Microsoft-Windows-Setup_neutral/ImageInstall/UserData/AcceptEual to true

Here is the autounattend.xml:
