The clues are in your screens with the D drive capacity at 400 MB and the partition size is 668 GB.
If you need to get the laptop working I suggest a new HDD (500GB drives run under 50 bucks) then restore the OS then your files from backups.
Windows PCs have not proven to be reliable enough to run without backups so that should bring the machine back.
So my hp laptop just blew up on me and it kept trying to repair and restart itself but I was getting a HDD error.
I have my other laptop and I plugged the HDD into an enclosure and plugged it into the working laptop. It reads the new drive D:/ but there are only 15 files on the drive. I ran tests and it says there should be a lot more than that on it.
I attached some screenn shots... am I looking in the wrong area for my files? Just really need some excel documents and other work related files.
I attached a few screens...
