I'm trying to install Windows 2012 via Windows 2012 WDS. The installer displays the following error message: the partition selected for the installation (1) does not exist on disk 0. Make sure the unattend answer file's imageselection \installimage setting references a valid partition on this computer, and then restart the installation.

the unattend file (created by the "Create Client Unattend" dialog)
