[SOLVED] C: drive gone

I cannot update anything. Windows updates fail, program updates fail, and any of my hardware monitoring or system items will not open at all. Windows was installed on an m.2. Has been running just fine for almost 2 years now. All of a sudden this happens. Is my OS potentially broken or does it sound like a hardware fail? Can't run anything as administrator to check any of the OS files for damage or to check the drive itself.

what are details of your pc?

have you tried safe mode?
  1. go to settings/update & security/recovery
  2. under advanced startup, click restart now button
  3. this restarts PC in a blue menu
  4. choose troubleshoot
  5. choose advanced
  6. choose startup options
  7. click the restart button
  8. choose a safe mode (it doesn't matter which) by using number associated with it.
  9. Pc will restart and load safe mode
if you can get into safe mode, is it still the same here?
can you run SFC scannow
right click start button

choose powershell (admin)

type SFC /scannow and press enter

once its completed, copy/paste this command into same window: (if you type it, the spacing has to be exact or it won't work)

Repair-WindowsImage -Online -RestoreHealth
and press enter


SFC fixes system files, second command cleans image files, re run SFC if it failed to fix all files and restart PC


if settings isn't working
open start menu
open power menu
while holding shift, click restart PC

this loads you into step 3 above.

Please note i have done this myself and it works but to stop myself getting into trouble i need to say its for you to read , its your decision as to wether or not you try it.​
For a problem like this, the actual problem needs to be discovered, before applying some random fix.

Here, we're not even close to suggesting rummaging around in the Registry.
In addition, any set of steps regarding the Reg needs to be prefaced with "Make a backup of the Registry first"
