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

3. 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)

/dev/sda1 contains a file system with errors, check forced.
