Learning all popular OSes basics + configs + working
One of my aim is to be a ethical hacker. I know that, one of the features of good hacker is that, the hacker must have a little knowledge and experience of some most popular OSes. The OSes I have experience are: Windows: Ms Windows 2000, XP, 7, 8, 8.1, 10, 10 pro Windows vista Linux: Ubuntu: Xenial Xerus, Mint Kernel: Android Debian: Kali Unfortunately, My experience in following OSes are: Mac: null; Chrome OS: 1/100; Fedora: null IOS X: null DOS: null My question is, How can I gain better experience in all most popular OSes, without buying, installing and uninstalling them after learning them. To Learn a OS: 1.) Buy/Download the OS 2.)Install in PC 3.)It takes some time to learn 4.)Have a experience on their working and system changing or modifying things if is open source 5.)Remove them from PC OMG, isn't there any other way? And please don't offer me the idea of using virtual machine/box! I am done with slow vbox/machine.
