Restore disk img without overwriting entire disk?

I'm upgrading a Windows system drive. I've created a disk image (using Disks) of the old 256GB drive and I want to write it to the new 1TB drive. But I'd like to not overwrite a partition at the end of the drive. There's plenty of room at the beginning of the drive. I just need a little advice on how to do the restore without stepping on that partition.
