I have upgraded to 14.04, installing it side by side with my Ubuntu 12.04. I have Windows8 as well. So now I have three - OS to boot from my laptop. (500 GB for Win8, 250 GB for 12.04 and ~ 200 GB for 14.04)

I do not know why I chose that in the first go, but now I want to revert back and combine the two Ubuntu's into one, using only 14.04. I had the option of doing a fresh install (I couldn't go for upgrade, idk why. I was using USB to install) but installing it side by side seemed a better idea then.

However, now I realize the horror I've done. My files are a big mess and will get messier. I have no clue what is where and its an unorganized chaos.

Is there a way to combine 14.04 and 12.04? Do I have to delete both of them and do a fresh install? How to do that?

One possible solution is to boot 14.04, copy the files in your 12.04 home folder over to the 14.04 home folder. Organise them as you wish.

Make a backup on an external disk just in case.

Then boot a live USB using the "Try Ubuntu" option.

Next use Gparted to delete the 12.04 partition and enlarge the 14.04 partition. DO NOT REBOOT.

Reinstall grub using boot-repair.

You will have to reinstall any programs you had in 12.04 that you need.
