Gparted not showing unallocated space or partition usage

Ok just created the bootable usb and went to try it. It was really very smooth. Dual boot is required for some windows applications(though available on Zorin) and other reasons.
But then while booting up with Flash drive I found Tocblock error database may be corrupt error. Though I went to installer without having to do anything.
The main error arose when Zorin did not list correct partitions when I chose Something else.Can you please suggest a fix? Also in the file manager I am able to view free space and all.

I would perhaps look at using NeoSmart EasyBCD for your dual boot.

Looks like it is Private.

Can you please suggest a short video or something?

Ok I just fixed it by converting dynamic disk to basic disk.
