Trying to recover files from hard drive.

I've been trying for 3 days to rescue my files from my hard drive and so far this is what I've tried.

-Windows is an infinite loop diagnosing and repairing on start up saying it's trying to fix disk errors.
-I jump into safe mode but that doesn't help it does the same thing.
-I open up a cmd from recovery mode, the only drives I can access are D, E, F, G, H, and X but it does detect the C drive.
-I just can't access it, I get a I/O error when I just to run commands on that drive.
-I tried repairing the RMB boot(I think that's what it's called?) That didn't work.
-I boot into linux and try to force mount the drive but I get an error saying that I need to disable Hybernate/fast boot to be able to mount it.
-Jump back into recovery mode and open up a command prompt and try to run the command "powercfg /h off",
it says powercfg isn't a command.
-I run the "Dir" on "X:/Windows/System32" but most of the system32 files are gone
along with the one that allows me to run the "powercfg" command.


I've also tried using a restore point but there aren't any and I've also tried refreshing the pc but that doesn't seem to be working either.

I'm at a lose and I really just want to rescue my files.

My last idea was to install windows on an external HDD and try to see if I can rescue my files within windows.

Any ideas would be really appreciated and I'm willing to try anything at this point.

Thank you for your time.
