Ubuntu recommends at least 25GB of free storage for smooth running, hence, I’ll choose 30GB.

Select the path you want to store and allocate the size based on your requirements. Since we have selected the VDI file type, we now need to store that single file on our host system. Of course, we would select a “Dynamically Allocated” option to mount more space at a later stage. But if you select a fixed size, you cannot add extra space after creating a virtual machine. In the future, if you want to increase your drive space, the dynamic allocation can allow you to do so. Here comes how to decide the scalability of your virtual hard disk. However, it is highly recommended to not choose less than 1GB.

For example, if your host system has 8GB or 4GB RAM, you should select half of it (4GB or 2GB) for better performance. Here, you have to choose the base memory based on your host system RAM size. So, click on continue and move to the next step to select the RAM size.

Virtualbox - Creating A New MachineĮnter a new name for your operating system in a prompt window. Now open the application and you’ll notice a symbol indicating “New.” Click on the same symbol or use keyboard shortcut CTRL+N to create a new virtual instance. I hope you’ve successfully set up your VirtualBox. The installation will finish in two minutes and you’re ready for the second part, i.e., creating a virtual machine for Ubuntu. In each wizard window, you don’t have to do anything except click on the next and keep the default setting checked.
