Installing Debian 10 Buster

In this article I will explain how to install the Debian 10 Buster operating system. This instruction is suitable for installation on physical equipment or a virtual environment (VirtualBox, VMware, etc.).

Minimum hardware requirements

Downloading the installation image

You need to get the ISO file from the Debian download page for network installation or installation of CD/DVD images. I recommend using a minimal CD image for network installation to download only the necessary packages. Then you need to create a bootable USB drive or attach the ISO file to a new virtual machine in your virtual environment.

Burning a Debian image to a USB drive

You need to write the installation image to the USB drive from which the system will be installed. To do this, use any software of your choice. I can recommend you the Etcher cross-platform utility. I used to use the UNetbootin utility, but at some point it stopped working.

In the utility, select the installation image and the USB drive to which you want to burn it:

Starting a bootable USB drive

Now you need to restart your computer and boot from the USB drive. To do this, you need to press a special function key to open the boot menu when loading BIOS/UEFI. Each computer manufacturer may have different function keys to launch the boot menu, usually one of the keys F2, F8, F9, F10, F12 or ESC. From the menu, select the bootable USB drive from the list of devices and press Enter.

Choosing a Debian installation option

After loading the USB drive, you will see the installer menu with several installation options. Select the "Graphical install" option and press Enter:

First, you will be asked to select the language that will be used for the installation process. Please note that your chosen language will also be used as the default system language:

Then you will be prompted to enter the hostname (node) to identify your system with other devices (nodes) on the network:

You can also enter a domain name or leave the field blank if the computer does not have a network domain:

Setting password for root user in Debian

You need to set a password for the root user (system administrator account). The root user must not have an empty password:

Partitioning disks in Debian

Now you need to prepare the disk: add partitions, specify the desired file system. In this instruction I will use the first option "Guided - use entire disk":

Next, all available disks (partitions) on your computer will be displayed. Select the disk you want to partition:

Configuring package manager in Debian

You will be prompted to scan additional CDs or DVDs for use by the package manager (apt). But we will skip this step because we are using a network installation:

Next, you need to configure the Debian archive mirror for the package manager. Choose your country or the country closest to you:
