I wanted to update my Ubuntu 13.04 OS to 14.04 Os. I downloaded the 32-bit (.ISO) file for the 14.04. Since, i run both Ubuntu and windows on my laptop, i was wondering if i can just update Ubuntu without losing all my current win and Ubuntu files. Is it possible? or do i need to install it fresh? if, in fact, update is possible, can anyone tell me how to do it? Also, i have tried to mount the .ISO file using various software, but my software center has gone nuts; it doesn't let me install any software.
Yes it is definitely possible
