Ubuntu 16.04.1 LTS doesn't start/boot

Question

I am new for Linux environment. I have installed Ubuntu 16.04.1 LTS and used for a while. I just turned my PC on and it showed me GRUB prompt. I do not know how that happened. Please, any help? I have my data in the laptop that I am afraid to lose so I did not try to fix it myself.

Here are the images of my PC.

Additional - and in fact, key, info:

Solution

You're not able to boot normally becuase you've got a "dirty" file system on /dev/sda2.

At the GRUB menu, choose Advanced Options, the choose Recovery Mode, then choose root level access. Once there, type sudo fsck -f /dev/sda2. Run this more than once if there are errors.

When completed, type reboot.

Let us know how you do. Cheers, Al

Select kernel 4.4.0-38 kernel and hit 'enter' - on second screen You attached. Is then the system starts up ? - How do You partition your hard drive ? - Do You have LVM ? - Do You have dm-crypt (encrypted hard drive) ?

How did you figure it out? There is nothing on this page related to /dev/sda2. Isn’t something missing in the current version of the question?

'cause I'm smart... giggle. Actually, I looked at the OP's pictures that he posted at <s22.postimg.org/x5kqesrbl/IMG_7395.jpg>. Cheers, Al
