In this article, we will explain what Debian Live is, how to download it, how to create a bootable USB drive with it, how to boot from it, how to try it, and how to install it. By following these steps, you will be able to experience Debian on your own computer without affecting your existing system.
What is Debian?
Before we dive into Debian Live, let's briefly review what Debian is and why you might want to use it.
A free and open-source operating system
Debian is an operating system that consists of free and open-source software. This means that you can use it without paying any fees, modify it according to your needs, and share it with others. Debian is also developed by a community of volunteers who collaborate over the Internet. You can join them if you want to contribute to this project.
A stable and secure Linux distribution
Debian is based on the Linux kernel, which is a core component that manages the hardware and software resources of your computer. On top of that, Debian provides a set of basic programs and utilities that make your computer run. These include a graphical user interface (GUI), a package manager (APT), and other tools that make it easy to manage thousands of software packages on your system.
Debian is also known for its stability and security. It has a rigorous testing process that ensures that only well-tested and bug-free packages are included in its stable releases. It also provides regular security updates for its packages during their lifetimes. You can rely on Debian for running critical Continuing the article: A versatile and flexible system for various devices and architectures
Debian is not limited to one type of device or one type of processor. It can run on desktops, laptops, servers, embedded devices, smartphones, tablets, and more. It also supports a wide range of architectures, such as 64-bit PC (amd64), 32-bit PC (i386), ARM, MIPS, PowerPC, and IBM S/390. You can choose the flavor and the architecture that suits your needs best.

What is Debian Live?
Debian Live is a special version of Debian that can be used without installing it on the hard drive. It is a self-contained system that runs entirely from a CD, DVD, or USB key. You can use it to try Debian before installing it, or to install Debian from the live system itself.
A self-contained live system that can boot from a CD, DVD or USB key
Debian Live contains a minimal Debian system that includes a graphical user interface (GUI), a web browser, a text editor, a terminal emulator, and some other basic applications. It also includes some tools for system administration, such as GParted, Synaptic, and the Debian Installer. The live system does not modify any files on the hard drive, unless you explicitly choose to do so.
A way to try Debian without installing it on the hard drive
Debian Live is ideal for testing Debian on your computer without affecting your existing system. You can boot from the live media and explore the Debian environment without making any permanent changes. You can also test the compatibility of your hardware with Debian and see how well it performs. If you encounter any problems or have any questions, you can use the live system to access online documentation and support forums.
A method to install Debian from the live system using Calamares Installer
Debian Live also provides an easy way to install Debian on your hard drive. Starting from Debian 10 Buster, the live images contain the end-user-friendly Calamares Installer, a distribution-independent installer framework that guides you through the installation process step by step. You can launch the installer from the desktop or the menu and follow the instructions on the screen. You can choose your location, timezone, username, password, partition scheme, and more. The installer will copy the necessary files from the live system to your hard drive and configure your new Debian system.
How to Download Debian Live?
If you want to use Debian Live, you need to download an ISO image file that contains the live system. An ISO image file is a single file that contains all the data of a CD or DVD. You can then write this file to a blank CD or DVD, or to a USB key, and use it to boot your computer.
Choose a flavor and an architecture
The first step is to choose which flavor and which architecture of Debian Live you want to download. A flavor is a variant of Debian Live that comes with a different desktop environment and a different set of applications. For example, you can choose between GNOME, KDE, LXDE, Xfce, Cinnamon, and MATE flavors. A desktop environment is a collection of software that provides a graphical interface for your system. It includes elements such as menus, icons, panels, wallpapers, widgets, etc. Each desktop environment has its own look and feel, features, and performance.
An architecture is a type of processor that your computer uses. As mentioned before, Debian supports various architectures, such as 64-bit PC (amd64), 32-bit PC (i386), ARM, MIPS, PowerPC, and IBM S/390. You need to choose the architecture that matches your computer's processor. If you are not sure which architecture you have, you can use a tool like CPU-Z or lscpu to find out.
You can find a list of available flavors and architectures for Debian Live on the official website. You can also read more about each flavor and each architecture on the Debian wiki. Choose the one that appeals to you most and suits your hardware best. Continuing the article: Download the ISO image file from the official website or a mirror site
Once you have chosen your flavor and your architecture, you can download the ISO image file from the official website or from one of the mirror sites. A mirror site is a copy of the official website that is hosted on a different server, usually in a different location. Using a mirror site can speed up your download and reduce the load on the official server.
To download the ISO image file, you need to find the link that corresponds to your flavor and your architecture. For example, if you want to download the GNOME flavor for the 64-bit PC architecture, you need to find the link that says \"debian-live-10.10.0-amd64-gnome.iso\". The number 10.10.0 indicates the version of Debian Live, which is based on Debian 10 Buster. The letters amd64 indicate the architecture, and the word GNOME indicates the flavor.
Click on the link and save the file to your computer. Depending on your internet speed and the size of the file, this may take some time. The size of the file varies depending on the flavor and the architecture, but it is usually between 2 GB and 3 GB.
Verify the integrity and authenticity of the downloaded file
After downloading the ISO image file, it is recommended that you verify its integrity and authenticity. This means that you check that the file is not corrupted or tampered with during the download process. To do this, you need to compare the checksum of the downloaded file with the checksum provided by Debian. A checksum is a unique string of characters that is generated from a file using a mathematical algorithm. If two files have the same checksum, they are identical.
To verify the integrity and authenticity of the downloaded file, you need to follow these steps:
Download the SHA256SUMS and SHA256SUMS.sign files from the same directory where you downloaded the ISO image file. These files contain the checksums and signatures for all the ISO image files in that directory.
Verify the signature of the SHA256SUMS file using GnuPG, a free software for encryption and digital signatures. You need to import the Debian CD signing key and then run this command in a terminal: gpg --verify SHA256SUMS.sign SHA25
