    "without any drive partition" You must have a "/", – Rinzwind Sep 6 '16 at 13:04
  • @Rinzwind I'm guessing the OP means that the block device is unpartitioned i.e. / (and everything under it) is on /dev/sdb rather than /dev/sdb*n* – steeldriver Sep 6 '16 at 13:24
  • No this is already installed and I think it appeared bcoz of my mistake as I change the crypt lugs format to NTFS and yes it is unpartitioned pls help me what to do – anand Sep 7 '16 at 19:40

I had the same issue before and I solved it according to the following steps:

  1. I've created a USB key with the live of Mint distro and I booted the machine with it.
  2. List your partitions using the following command:

sudo fdisk -l /dev/sda

I got the following output where sda the only drive on my machine, notice that your linux partition is /dev/sda1

Disk /dev/sda: 232.9 GiB, 250059350016 bytes, 488397168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xa71bc45b

Device     Boot     Start       End   Sectors   Size Id Type
/dev/sda1  *         2048 480393215 480391168 229.1G 83 Linux
/dev/sda2       480395262 488396799   8001538   3.8G  5 Extended
/dev/sda5       480395264 488396799   8001536   3.8G 82 Linux swap / Solaris
  1. Then, I executed the following command which rescue my disk again

sudo fsck -yv /dev/sda1

and I got the following result

fsck from util-linux 2.27.1
e2fsck 1.42.13 (17-May-2015)
