Installing Kali Linux on the virtual machine

Once the virtual hard disk has been prepared and completed by following the steps from the previous section, we can then begin the actual Kali Linux installation process. In the Oracle VM VirtualBox Manager, which is the main OS management window for VirtualBox, we can see that the VM prepared for our Kali Linux installation is now available.

To the middle of the screen, we can also see the resources assigned, such as the Name and Operating System type in the General section, and the amount of RAM assigned in the System section. Other settings, such as the VRAM (an acronym for Video RAM), Network and Display settings can also be accessed within this section.

To begin our Kali Linux installation, click on the Kali-Forensic entry to the left and click on the green start arrow:

In the next step, we must locate the Kali Linux ISO image that we downloaded from the Offensive Security website. Click on the folder icon next to Host Drive 'D:' and search for the downloaded Kali Linux ISO image:

Once the ISO image is selected, you will notice the selected entry changes to kali-linux-2017.2-amd64.iso (2.81 GB). Click on Start to begin the boot process:

After clicking on Start, the Boot menu displays the various options available, including the live versions of Kali. For this demonstration, we'll be choosing the Graphical install option to install Kali to the virtual hard drive:

As a side note, I should also draw your attention to the Live (forensic mode) option, which would be available to us when booting from a DVD, flash drive, or other removable storage media. It's a good idea to always have a copy of Kali Linux, in the event that a live response may be needed.

Ok, back to our installation. After clicking on the Graphical install option from the Boot menu, we're prompted to choose our language, location, and keyboard layout.

In the next step, we give our Kali Linux guest a Hostname, which is the same as a username in a Windows environment:

For the Domain name area, I've left this blank, as I won't be joining this host machine to a domain.

When setting the password, be sure to use one that you can remember. It makes no sense using a complex password, 16 characters long and consisting of uppercase and lowercase letters, and alphanumeric characters, if you can't remember the password upon booting:
