I am usd to seeing a C:\ with a system reserve and MBR. I don't know about clear white and lines.

Does the attachment look correct after installing Windows 1803 with today's updates and after being cleaned up such as defrag etc.?

I do not know much about disc management with the gray areas etc.

So does my attachment look as though it should to function properly. Does it need any fixing?

Thi is aa more current attachment with the external drive detached.

They both look good. Nothing to worry about.

thank you very much for your kind comments
