Ubuntu boot problem Stuck

Question

I was having Ubuntu 16.04 and I was trying to dual my system to win7. While creating partition for win7 the partition got corrupted and resulted in a initramfs Problem. I cleared the issue by running fsck but now when I boot into my system I get stuck at the following stage, I tried attaching the image here but wasn't possible I'll try to write the boot display error message.

The boot up page get stuck at the below result once:

Answer 1

Your system has suffered from catastrophic data loss. (Hopefully this hasn't occurred in your /home partition as well.) You could try to recover it, but I don't have the experience to suggest how. Instead, please follow these instructions to make sure your data is safe:

1. Obtain a Ubuntu Live CD / Live USB. You probably already have one of these somewhere, but if not you can follow this guide.
2. Boot from the Live CD. If you don't know how to do this, look it up based on your computer model. If you don't know your computer model, try mashing all of the Fn keys while the computer is starting up but before it reaches Ubuntu.
3. While you're waiting, ensure that a large external drive is plugged in.
4. Choose Try Ubuntu.
5. Open a file manager.
6. Select the partition containing your /home folder or its contents.
   
   You might find an empty /home folder; don't panic – it just means that your files are stored on another partition.
7. Copy the files that you want to keep.

Now that you have recovered your files, you can make the system bootable again:

8. Find the /bin folder of your computer (not of the live CD).
9. Start a terminal in this folder.

10. Run the command:

    cp -L /bin/sh .
    

11. If this prompts to overwrite a file, stop; an assumption I made about exactly how your system was broken has been proven wrong.

12. Restart your computer, this time booting normally.
13. You should be greeted to a recovery console. If not, see step 11.

From here, you might be able to get your system up and running. I doubt it though; it's probably easiest to reinstall once you've verified that you have all of your files.
