Developing in Unix enviroment!

Good evening r/cscareerquestions , as a beginner web developer I have a question that I want to ask. I am a Windows user and I've been developing in .Net, Html/css during couple of my college years. I got an internship at a company which specifies in web development using open source: php language, couple frameworks (Silex and Symfony). They are also using Drupal, React js for front-end. After hearing this I downloaded Oracle vmbox and installed ubuntu, set up LAMP and got myself into some open-source to understand how things work and just to get used to. My question is, should I try to make separate particion and install ubuntu for this purpose (studying before starting internship, working with during internship), or just stick to the vmbox and develop using that? This question arised after having some delay, lag using vmbox. My lapotp is not the strongest one, it has 4gb ram, so I am not sure if my hardware can handle double partition and if it is a correct choice , if you have any other suggestions to this case, your offers are more than welcomed!
