I did this thing and win 7 is gone. Please help me to get me that back. It is important as lots of my work files are not opening.

sudo add-apt-repository ppa:danielrichter2007/grub-customizer sudo apt-get update sudo apt-get install grub-customizer

  • You should be able to access the files from ubuntu by mounting the windows partition. – mchid Dec 02 '15 at 03:49
  • I think you are right. Can you help me how to do it as I am unable to do it. I hibernated my win 7 and now it is not mounting. – Gaurav Agarwal Dec 02 '15 at 03:55
  • Use blkid to determine the /dev/sda number of the windows partition, then run sudo ntfsfix /dev/sdax but replace sdax with the actual number of the windows partition, such as sda5 or sda1, whatever it may be. You should be able to mount the partition after running that command. – mchid Dec 02 '15 at 04:03
  • I typed sudo ntfsfix /dev/sda5. But message comes "command not found. Thank you for your quick help. I also tried to mount the drive but message coming "only root caan do that" – Gaurav Agarwal Dec 02 '15 at 04:32

You could try this way Dual boot: how to target the new grub but you may need to Reinstall GRUB instead of Restore MBR.

  • I checked and found this message for my C drive: Error mounting /dev/sda1 at /media/gaurav/9C1CF5951CF56AA2: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sda1" "/media/gaurav/9C1CF5951CF56AA2"' exited with non-zero exit status 14: Windows is hibernated, refused to mount. Failed to mount '/dev/sda1': Operation not permitted The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option – Gaurav Agarwal Dec 02 '15 at 03:50
