I cheked in cmd using sfc command and tried to repair it using the tutorial Extract files from windows 7 DVD..But also the damaged is not replaced..how do I replace ?
Repair install yesterday and you would have been done yesterday.
You won't loose your personal files, pics or anything.
-or-
If you have a System Image. Windows or Macrium set aside. Faster and easier.
I had to do this last week with a Windows System image and Back up I had made.
Did the image and selected to install back up files that were the newest but good.
This is for the Windows Sytem Image which is what I did. Worked perfect.
I used Step 2- #2 from inside Windows- no disk needed. Step 2 you go from #2 to #5 without using Win disk.
Step 3 and 4 use Win 7 disk if you can't get into Windows. System Image Recovery
One or the other.
That is what I would do if it were mine.
