I too can confirm that I am experiencing this issue – running FOG Server 1.1.1 on Ubuntu 12.04.4 LTS.

Our Windows 7 PC’s original image was created from a clean windows 7 install (updates, couple programs installed - acrobat, etc, nothing special really) and imaged using the “Single Disk (NTFS Only) Resizable”

The partitions on the disk are as follows:

disk0part0: System (300MB)
disk0part1: OS (rest of drive - 248GB)

When I push the image to an identical spec’d PC, the image completes successfully but the cloned PC does not boot to windows (blank screen with single blinking “_” underscore )
