I am a novice Python programmer and I am having trouble creating a Virtual Box, hopefully this is an easy fix!
So, I've been using a virtual machine for my computational physics class, but it is connected to my physics department, so I can't use it for my research, I want to create my own. I have a Mac and would like to build a Ubuntu Linux based virtual machine, but am having trouble.
So I start in the Virtual box Manager and click "New", create a machine type Linux version Ubuntu, keep the default memory size, choose to create a virtual hard disk now (VDI), keep it dynamically allocated, and create the New Virtual Hard Disk on my Desktop. I then try to open it up but then it asks me to "select a virtual optical disk file or physical optical drive containing a disk to start your new virtual machine from" but there is none to select from and it does not work without one.
Can someone see what my problem is? Is there a way I can get this virtual optical disk file? Is there something I can download for free online? I'm sure it's something easy. Thanks if you can give me any advice!
