Stuck in automatic repair loop

---- Update:

My windows 10 won't boot. It seems like my windows installation is now located at drive D: (it used to be C:, which now seems to only contain a folder named Boot).

I tried rebuilding my BCD according to this page: https://answers.microsoft.com/en-us/...3-cc275e1d9fbf

I tried switching the labels in regedit but it doesnt seem to save the changes.

---- Original post:

I noticed that my computer did an update when I shut it down last night. The blue end screen said something about "configuring updates" like Windows use to do sometimes.
Earlier during that day the only thing I remember that I changed or install was Microsoft SQL express 2008. I doubt this has something to do with it.

Anyway today it doesn't boot into Windows. Its stuck in the automatic repair loop.

I have tried the following:

- Safemode:
Just restarts and comes back to automatic repair

- I tried going into the Command prompt and typed cd C: (which is where Windows should be installed)
In there I could only find a folder named Boot

- Shut down, plug out DC cable, holding power button a few seconds
Automatic repair again

- Resetting my PC (keeping files but removing settings, apps, etc.):
Starts showing "Resetting this PC" and showing a percentage counting up.
When its done it shows automatic repair on the black screen again but the blue screen shows something ifferent:
"Your PC/Device needs to be repaired
The operating system couldnt be loaded because the NLS data is missing or contains errors.
Error code: 0xc0000225
You'll need to use recovery tools."

What has happened and what should I do?

Bitlocker...have you set it up?

Open Command Prompt (Admin) and copy paste the following.

sfc /scannow

In cmd, windows seems to be located at X: instead of C: like it use to. Is this wrong?

Open Disk Management, Right click on Drive X ....Change drive letter to C.
Then repeat sfc /scannow
