the disk drive for /dos is not ready yet or not present

Question

I had Windows and Ubuntu 14.04 installed on my computer. My disk drives were mounted in Ubuntu. Only windows installation drive were mounted to /dos. But after re-installing windows, I had to recover Ubuntu boot and since then

The disk drive for /dos is not ready yet or not present Continue to wait or press s to skip mounting or M for manual recovery

and every time I have to press "s" to enter ubuntu. I tried remounting but didnot work. On disk info application it showing "Device- /dev/sda2" . What should I do?

Edit:

/etc/fstab:

# <file system> <mount point>   <type>  <options>       <dump>  <pass>

-> This came entering "sudo lsblk"

and this came aftering "sudo blkid"

N.B. - I tried editing /etc/fstab by reading How to automount NTFS partitions? . But still no good
