VirtualBox

VirtualBox is similar to VMware Workstation Player, and is a hypervisor that's an open source and completely free desktop application from which you can run any virtual machine, once it's installed on the host operating system. VirtualBox can be downloaded from this URL:

Click on Next and provide the amount of RAM required for Kali. We recommend at least 1 GB. By clicking on Next, we will be creating a virtual hard drive for Kali on the host operating system. Click on Next to choose the hard disk file type: mostly, we select VDI (Virtualbox Disk Image), as shown in the following screenshot:

By clicking on Next, we will be creating the size of the HDD, as shown in the following screenshot:

Finally, we have to go to Hackbox | Settings to load the ISO image as an external drive, as shown in the following screenshot:

That's it; we should now be able to see the following screen and install Kali to VirtualBox without any issues:
