Infinite Windows repair loop

Hi,

I have dual boot Windows 7 and Ubuntu 14.04. Everything worked fine until it froze one time, I had to restart the computer. After that I was not able to start Windows. I can start Ubuntu without any problems, however Ubuntu cannot mount Windows. Everything is on 256Gb Samsung SSD. When I try to access Windows files from Ubuntu I get error (2) below.
When I try start Windows, it does repair and says (1).

I spent all day trying to figure out how to fix it, but no luck yet. I also don't understand what's wrong exactly.


(1) Root cause found:
System Volume on disk is corrupt. Repair action: File system repair(chkdsk)
Result: Completed Successfully. Error code = 0x0.

(2) Error mounting /dev/sda2 at /media/aziza/Windows7_OS: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda2" "/media/aziza/Windows7_OS"' exited with non-zero exit status 13: ntfs_mapping_pairs_decompress() failed: Input/output error
Failed to load $MFT: Input/output error
Failed to mount '/dev/sda2': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details

Have you tried running Startup Repair from a Windows 7 System Repair Disk or a Windows 7 Install Disk?
