Mysteriously All my files are Missing after Windows Update

The drive letters may differ in WinRe.

I asked you earlier about browsing in using the Win7 Installation or Repair disk. You never replied so now i need to ask you again. I don't like to have to ask again as it means the required thoroughness is not being met. Either keep up with every single step or take it to a shop.

Sorry I did follow your instructions but didn't update you...

When browsing using repair disk, the files are still not there...

Have attached screenshot of c:

I dont remember 100% how I rolled back to win 7 but im pretty sure I used, windows own software..

Did you try Unhider? Any indication you had infection which hides files?

There's only 10gb space used above the OS so try to calculate what's using that as it might mean the files are there and hidden or dropped in the wrong folder or partition.

Try running Startup Repair to see if boot files need repair or redirecting from Win8.

I have ran this before > Unhide Download currently running it again now...

I have done startup repair numerous times, it seems like it does repairs but at the end says that startup repair was unable to....

I also ran combofix

Unhide results..

Ok I am downloading the .iso file, I am assuming I can just mount and run or burn and run. Will update you as soon as I have done it...

I had around 400gb of files before this problem...

I didnt realize the .iso file was to reinstall win7, I thought it was a software to unhide my files...

So I should do a re-install of windows? wouldnt that make it harder to get my files back? I have my original win7 cd for my computer shall I use that instead?

If you did not have your files backed up then they may be lost.

You can run file Recovery software like Recuva - Features
to see if it detects them.

Ok I understand, I guess that is the only option left. Thanks for your time.
