How does VirtualBox work?

[holygamer]

Once I install the program how do I install Windows? Do I create a virtual Windows 7 and then I can copy and paste that to create another virtual Windows 7.

I'm only using this to install unstable programs that I don't want to install on my main Windows installation. So each box would just have 1 program so if anything goes wrong I can just delete the box.

After you installed VirtualBox.

Launch VirtualBox and click on New button to follow guide to create virtual machine, select name and OS, set memory and create virtual hard disk.

After created Windows 7 virtual machine, double click or click on Start button to start virtual machine, it will ask you for Windows 7.iso then it will run setup to install Windows 7.

OK but after it's setup can you just copy and paste a virtual machine to create another one or do I need to go through the Virtual Machine creation process again?
