Tried to create custom image, but it keeps trying to capture instead of install

Hi,

I'm trying to test WDS, and I was able to create an initial Win7 image from the original Win7 DVD and then PXE boot to install that on another machine.

So then, I wanted to try to build a custom image and followed the steps here:

https://technet.microsoft.com/en-us/library/Dd637993(v=WS.10).aspx

However, if I PXE boot now, I get the original image and the new image (CUSTOMxxxx) and if I select teh CUSTOMxxxx one, it starts up and then wants to do another capture, rather than starting and doing a Windows installation using the custom image.

It seems I must've missed something after the capture, but I've gone through the procedure again and also tried booting with a completely different machine and it keeps bringing up that capture thing.

Can anyone tell me what I need to do so that I can PXE boot and install my custom image?

Thanks,

Jim
