Ubuntu 22.04 LTS (Jammy Jellyfish) was officially released on April 2022, 21, and will receive software support through LTS (Long Term Support) for another 5 years, meaning we won’t have to worry about updates coming until April 2027. The operating system includes the GNOME 42.0 desktop environment. In this description, it is installed on a 64-bit machine running UEFI, where a hard disk with a GPT partitioning scheme is used for this purpose.

If you are running operating systems in VirtualBox, it is a good idea to install Guest Additions on the guest system, which will provide a greater degree of compatibility with the virtual hardware so that the guest system can make better use of the available hardware resources. In this description, we will install the Guest Additions package on a system with a Debian 6.1 (Bullseye) KDE desktop environment running in VirtualBox 11.

In this description we will install a Debian 11 (Bullseye) minimal server, which consists of the basic Debian 11 system and some basic program installation and configuration. The server will later serve as a basis for additional server installations. On this page we will install the base system.

VirtualBox can be installed on a variety of operating systems, including all versions of Windows. However, there are still issues with Windows 11. The current version of Virtualbox (6.1) theoretically supports Windows 11, but there are problems during installation. This troubleshooter resolves this issue so that you can install the current latest version of Windows, 11, without any problems.

In this dual boot description, we first install a Windows 11 operating system and then an instance of Ubuntu 21.10 (Impish Indri) Linux. It is installed on a 64-bit UEFI-based machine, where 64-bit systems are mounted on two partitions on a hard disk with a single GPT partitioning scheme. On this page, we'll review the prerequisites and then install Windows 11.

Thanks to virtualization, we have the ability to run another operating system within our computer’s existing operating system. This can be used for a variety of purposes, in this case I will use the free VirtualBox virtualization program for the installation, in which I will install the guest operating systems that are the subject of the tutorials. In this description, in VirtualBox running on a Linux host, I create a guest machine for Linux or Windows operating systems with a graphical desktop environment that requires more hardware resources - and therefore different settings in some places - than the previous version for Linux base systems.

Debian 11 (Bullseye) was released on August 2021, 14, and is available in a variety of desktop environments. In this description, we will install the desktop version of KDE Plasma, using the Calamares installer in the Live version, which offers a convenient, clean and simplified installation process. This installation is performed on a 64-bit UEFI machine where the Debian 11 (Bullseye) operating system is mounted on a hard disk with a GPT partitioning scheme.
