Encrypted hard disk data recovery
I have a hard disk with a crashed Ubuntu system . while installing the system I checked the "encrypt my hard disk (or something like that) " check box . and now the system has crashed . so how do I recover my /home and /etc folder .
Ubuntu system is 15.10 .
As I am a newbie in Linux I don't know how to solve the error that's crashing the system but the home folder is really important .
So , how do I recover my /home and /etc folder from an encrypted hard disk.
More information
After the Ubuntu logo it shows a dialog box which says "there seems to an error in your graphics or input devices" and done. I tried 100's of solution (not literally) and after some 4/5 hours of trying and trying now it doesn't show the recovery options or the dialog box. It takes me to shell aks or something like that.
I even tried to upgrade it to same OS. While in the process of upgrading it showed that no operating systems were detected, and I rolled back. Then I made a USB bootable stick and tried the "try Ubuntu" but it said partition cannot be mounted. I even took out my laptop's hard disk and connected it to another Ubuntu machine (as a external hard drive ) but it only showed me the grub files not my hard disk files.

There are two possibilities of encryption within Ubuntu.
- Full disk encryption
It means that the whole disk is encrypted. Immediately after starting (right after booting the kernel) you are prompted for a password. It looks like this: http://imacify.com/wp-content/uploads/2013/08/Ubuntu-FDD-lock-Screen.jpeg
This does not seem your case, because your problem happens later in the booting sequence.
Anyway, this guide shows you how to access an encrypted volume using a Ubuntu Live CD or USB stick. You should be able to recover some data and copy them over to another disk. Good luck :)
https://alvinabad.wordpress.com/2012/09/22/how-to-recover-a-luks-encrypted-disk/
- Home folder encryption
In this case, home partitions are encrypted on a per-user basis.
Here are a few resources for you:
http://www.howtogeek.com/116297/how-to-recover-an-encrypted-home-directory-on-ubuntu/
https://help.ubuntu.com/community/EncryptedPrivateDirectory
You should try to recover your data first. But I also think that it should not be too hard to restore functionality to that box.

I get a shell saying (initramfs) and cryptsetup is not found . and for the dialog I see is " you are running in low graphics mode" I see this dialog even in the live cd

So you have a corrupted initfamfs. If it complains about cryptsetup then you are in case 1 of my answer. Live CD should not be affected by this: are you sure you are booting it correctly?

After the Ubuntu logo it shows a dialog box which says " there seems to an error in your graphics or input devices " and done .
