So my college teacher told me today that, for developing, the Ubuntu 14.04 is more stable than the 16.04 and also said that there is a huge diference and with the actual version I'm probably going to have an adventure trying to fix thousands of errors. So I got worried because I installed the 16.04 and can't find a link that gives me something like UEFI Bootable Ubuntu 14.04. Was wondering if you guys can help me showing how I can uninstall the 16 and where to get the 14 and if you think it is really necessary the older version.
Ps.: He is the Object Oriented teacher and we will be using c++, java and ruby. It is a dual boot with Windows 10 and I do not have intention of loosing Windows files :D
