Installing Microsoft Windows Automated Installation Kit

When installing WAIK off a USB stick or hard disk, you may get an error “Please insert the disk: Windows Automation Installation Kit CD”

I found the perfect answer here: http://richardyoung.wordpress.com/2011/11/09/silent-install-of-the-waik-fails-with-error-please-insert-the-disk-windows-automation-installation-kit-cd/

Basically, get something like Orca (if you've never used it before, this article may help http://support.microsoft.com/kb/255905) and create a transform.

You need to change the values in the Media table. I changed everything that had a volume label "KB3AIK_EN" to "DEFAULT".

Then ran the command

msiexec /i WAIKX86.msi TRANSFORMS="waik.mst"

Change the msi to the relevant one (e.g. use waikx64.msi on a 64 bit platform) and put in the full path of the MST file.
