If you're attempting to create an image from an HP DC5700 you may receive errors if you have not repartitioned the hard drive. HP ship these machines with a hidden restore partition in front of the main NTFS partition. As the hidden partition is not a NTFS partition FOG will give an error when attempting to read it.
- Remove all partitions on the computer using your favourite partitioning utility, such as fdisk or Partition Magic
- Create a standard primary NTFS partition and install Windows
- Set up your Windows installation as required
- Use FOG to create your image
