Please see attached image. I am not sure what happened when I reinstalled but usually that was a reserve partition i think made by the OS. well, its not anymore and I don't know what to do with that space.
You can ignore it.
Or you can use Partition Wizard bootable disk to add that space to C.
Take your pick.
When creating a disk image, do I select the unallocated space just to be safe during the backup? My concern, is that i will make an image of my duel boot and leave out the small unallocated partition. Then when I go to re-image the disk, there may be some error. What do you think?
Unallocated space is not a partition or part of a partition. It is unallocated space.
I'd be surprised if you could choose it as part of an image even if you wanted to.
I'd ignore it.
If it is bothering you just by being there, then use Partition Wizard to add it to a partition.
