[Autounattend.xml keeps asking to choose an operating system]

Thanks guys! I tried both your suggestions but the problem persists.

[Autounattend.xml keeps asking to choose an operating system]

I am attempting to create an image for silent installation of Windows 7 Professional x64. I have created the answer file as instructed from Step-by-Step: Basic Windows Deployment for IT Professionals page. I have placed the Autounattend.xml file in the root directory of the iso installation file. On installation the answer file is being detected but no matter what I try it keeps asking me to choose an operating system. Am I missing something? I am about to tear my hair out. Can anyone please help?
