input/output error during read on /dev/sda/

I have got myself stuck in a serious situation. There was problem booting my ubuntu after a hard shut-down. I used a live CD to run ubuntu. I installed boot-repair in it and ran it. To my surprise it not only removed my ubuntu but also my windows. Now I am not able to install ubuntu again because of this error. The report generated by boot-repair is in the provided link. Please help

Here are the screenshots of the smart data window from disks utility of my ubuntu partition.Screenshot of ubuntu partitionFirst screenenter image description here

Have you tried running fsck? It's a utility that checks consistencies in a file system and makes repairs. To run it you'll have to make sure the drive isn't mounted to avoid altering disk data and causing runtime errors. Boot from live DVD/USB and run fsck /dev/sda3 on the drive from your terminal.
