I can only read English, but I do know that the normal chkdsk is only 3 steps while the bad sector check is 5 steps, so you didnt check for bad sectors yet.
You wont be able to check for bad sectors while in windows, it will do it at your next reboot. So do this
Open a cmd.exe window and put in
chkdsk c: /f /r
and hit enter. It will say it cant do it because the drive is in use, would you like to schedule it. Hit y for yes.
Then reboot the computer and before windows logs in it should start, if it doesnt try again, it sometimes doesnt take for some odd reason.
And a bad sector check will take a while. Once done the results will be int he event viewer
