Restore of Differential backup - RAW Partition

Hi,

I'm testing out the True Image 2015 product and did a backup of my windows partition (it's a bootcamp on MacBook Pro). Did a full backup and a few differential backups. Then tried to restore to a second hard drive. The restore seemed to work but the partition that was created by True Image is in RAW format and not accessible. Note restore was performed on a second Windows only machine which had a USB hard drive (1TB) attached.

Prior to restore I created Acronis Universal Boot and booted the machine with this and ran True Image to do the restore onto the second hard drive.

Note the intent was not to boot from the restore on the second disk. Just to see if the restore would work and I can see the files.

Any help would be appreciated.
