I've been using Windows for about a decade now and I am planning to switch to another Operating System which is similar on how Windows Operates. I am currently using Windows for academic purposes such as writing document in MS Office Products, programming using Dev C++, Photoshop etc. These application are crucial since I am studying Computer Engineering and needed an OS that can handle IDE application and similar products like AutoCAD.
Can anyone suggest a different OS that maintains its user friendly interface and can provide similar function from Windows?
For the purpose of using AutoCad, well am sure MacOS can handle this without a doubt.
For alternative operating systems that can run this its best to visit the autocad website to see which OS is supported

However, is it possible to install two OS in one PC?
Very much possible, the process is called dual booting! For step by step tutorials youtube should be enough to walk you through
