Restore Issue

I have used Paragon Backup & Recovery 16 to create a single back up from a 4 GB compact flash card (CF card).
now using Paragon Backup & Recovery 16, i'm trying to restore it into another CF card with size of 8 GB.
I have formatted the 8 GB CF card with the same format as the source (NTFS). but when i want to do the restore i get following warning at the beginning:
"This partition contains data for loading operating system"
then i select continue, and restore job starts. but it fails immediately with the following error message:
"Partition is not valid"
i have re-tried getting back up and restore several times but it gives me same error every time.
here i have attached screen shots of the error messages.
i would appreciate it if any one could help me with this issue.
