Enabling this option is only useful for Unix systems. enable or disable EFI (for Windows 7, 8, 8.1 or 10, for example).Note that the ICH9 chipset emulation is experimental and is only useful for virtual machines with Mac OS X as guest OS. (The 'Network' option is primarily used to boot your VM through a PXE server.) change the amount of RAM allocated to your virtual machine.In the 'Motherboard' tab, you will find interesting informations. In this case, the virtual hard disk will be encrypted to protect the data it contains. In the 'Encryption' tab, you can enable the encryption of the virtual machine and use a password to reuse it. In the 'Description' tab, you can enter notes if you wish. This allows you to easily copy files from the physical machine to the virtual machine (and vice versa). enable or disable drag and drop between the host machine and the virtual machine.enable or disable the clipboard sharing between the host machine and the virtual machines (in one or both directions).In the 'Advanced' tab, you can choose the folder where snapshots will be stored.

change the type and version of the operating system installed on it.

manage the virtual network adapters of it.

Once you have created a virtual machine with VirtualBox, you will be able to modify many settings including :
