I have a Lenovo x220 laptop which I dual boot between Win7 and Ubuntu. I've been running it like this for about two years, and recently upgraded Ubuntu from 14.04 to 16.04.5 about two weeks ago, without any major issues.

The problem started after hibernating Windows. The last time I tried to boot into Windows after hibernating it just kept rebooting to the bios screen. So I booted into Ubuntu on the other partition and tried mounting the NTFS partition, and got the error message in the title. I accessed the SMART data via the disks app, and it says the drive is physically OK and correctly reads the disk partition structure.

Running ntfsfix gave the following results:

~$ sudo ntfsfix /dev/sda2

Volume is corrupt. You should run chkdsk.

So I ran TestDisk:

TestDisk 7.0, Data Recovery Utility, April 2015
Christophe GRENIER <grenier@cgsecurity.org>

Disk /dev/sda - 320 GB / 298 GiB - CHS 38913 255 63

     Partition                  Start        End    Size in sectors
> 1 * HPFS - NTFS              0  32 33    12 223 19     204800

  6 L Linux Swap           37883 251  1 38913  70  5   16535552

The first partition is a small 100 MB boot partition. The problematic one, where Win7 is installed is the second partition. However, TestDisk says that the boot sector on the partition is OK:

Disk /dev/sda - 320 GB / 298 GiB - CHS 38913 255 63
     Partition                  Start        End    Size in sectors
 2 P HPFS - NTFS             12 223 20 21464  73 49  344616960

Boot sector
Status: OK

Backup boot sector
Status: OK

Sectors are identical.

A valid NTFS Boot sector must be present in order to access
any data; even if the partition is not bootable.

However, if I choose List to try and list the files I get:

 2 P HPFS - NTFS             12 223 20 21464  73 49  344616960

Can't open filesystem. Filesystem seems damaged.

If I choose Repair MFT I get:

MFT and MFT mirror are bad. Failed to repair them.

As to why this happened, I'm thinking that it may have been the result of using TestDisk 7.1 Beta to restore some deleted files from the Linux partition and using the NTFS partition as the destination, while Windows was hibernated. It's the only thing I can think of...

So the question is, is there anything I can do?
