Windows 10: C: drive messed up

When I upgraded to Win 10, somehow that screwed-up my C: drive.

I'm using an HP desktop, specs:

As you can see, I have a 1TB hd. However, only 19.77GB are free. The remainder is on the K:. K: is the name I gave to that specific unallocated partition so I could continue to use my computer without difficulties.

Here's my disc management set-up.



Why was my C: altered and what can I do to get it back to it's original configuration?

Any help appreciated.

Windows 10 c: drive not accessable

I was trying to solve a problem I had with accessing several folders, following the steps on a web site, and

I got a message that the owner of the C; drive was being erased!

Since then I have no access to the c: drive, I keep getting "access denied", "you don't have the proper permissions", "you don't have read permission", and when I finally got into Safe Mode and clicked on C:/properties/security, it said "Owner: Unable to
display current owner".

I've tried more methods than I want to list trying to get ownership of the C: drive and set permissions back where they belong.

Where is the c: drive owner entered? Would I need to RegEdit? If so, please provide step by step because all I know about RegEdit is that it's dangerous to mess with.....

Any assistance would be greatly appreciated!
