Moving the image shouldn't matter as long as it is placed intact in the root of the drive.
Try running the backup utility from your new Windows install using Step Two here: System Image Recovery
Next try copying the backup to your HD, then reformatting the external NTFS Primary if it isn't already. Then copy the image back.
If you have a Seagate or WD HD you can use their free Acronis imaging apps located on their Support Downloads webpage which will reimage the same HD from another partition. Just change the file type in the browser box to "all" and browse into the .tib file to load image into utility.
You can also mount the image's .vhd file in Disk Management, then image the virtual drive it creates to the external using Macrium Reflect which many have reported works better: Virtual Hard Disk - Create and Attach VHD
