Check How to Install Qubes OS in VirtualBox

It may be one of the most secure operating systems and is frequently used by professionals concerned with computer security. Qubes OS is a free, open source operating system with a strong focus on security. It uses Xen-based virtualization, which enables users to quickly build, use, and delete isolated compartments known as qubes. To be easy to understand, each qube is constructed as a virtual computer that can be fully customized by specifying a purpose, nature, and level of trust. Here’s how to configure the Qubes operating system in VirtualBox, with Windows as the host operating system.

How to install the virtual machine

Open VirtualBox and choose Machine / New then choose a name for the virtual machine. For our installation, we will call it QubesOS-vm. Change the folder according to your needs and select Linux / Fedora (64-bit).

Click Next, and then select the size of memory (RAM) that you want to allocate to the virtual machine.

Click Next, select Create a virtual hard disk now, then click Create. Select VDI as the hard drive file type, and then click Next.

Now it is up to you to choose between a dynamically allocated virtual hard disk or a fixed size one. The fixed size option allows you to set a maximum size that will never change on the physical hard drive. The dynamically allocated option will only consume disk storage as it fills up. Eighty gigabytes is generally a good size for this type of virtual machine, but of course it all depends on your hardware and how much space you have left.

The next step is to configure the size of the virtual hard disk.

Click Create and wait for VirtualBox to finish configuring. The virtual machine environment is now ready.

Right-click on the new virtual machine and select Settings.

Change all the settings according to your needs and hardware. On the System tab, check Enable EFI (special operating systems only).

Go to the Storage tab, click the CD…
