This is my experience on installing openSUSE, the green chameleon operating system, Leap Edition version 15.2 to my computer. It is a family of GNU/Linux hence a distant sibling to Ubuntu with a distinct feature called YaST, the green tapir control panel, on top of its RPM software package basis. I installed it on a virtual machine in normal method as I used on Ubuntu. However, this can be used for actual installation to the real hardware directly including in dualboot mode. Thus, I share this with you by wishing it to be useful. Let's go!
