Been watching these great Edutainers giving us wonderful lessons and seen them switching back and forth between operating systems. I've been a Windows user since '95 (and have even dabbled in 3.0) but have little to no experience with Mac or Linux. So while going through some of the courses you offer it occurred to me I should probably familiarize myself with these OS's.
I'm currently use Windows 10 home and was able to download Oracle VM Virtualbox. I successfully installed and can run Ubuntu on Virtualbox however, to my knowledge, it is unable to run multiple ISO's at the same time (unless there's a setting I don't know about). Any help, tips or suggestions would be greatly appreciated!
