How to Install Debian 10 Buster 13

After several years of development, the Debian 10 Buster distribution was released. In this release, in addition to updating package versions, we will also see several other changes. Now the system can be downloaded in Live mode from the installation media, and in this Live mode, the ability to install using the Calamares installer has been added.

The usual Debian pseudo-graphic and graphical installer has not gone away and is available for selection at boot, and Calamares has been added for the convenience of beginners. In this article, we will see how to install Debian 10 step by step using the new Calamares installer.

System requirements

The minimum system requirements for the Debian 10 graphical version are:

  • RAM: 512 Mb
  • Disk space: 10 GB;
  • CPU: Pentium 4, 1 GHz;
  • Installation media: USB or DVD.

Preparation for installation

Step 1. Download the installation image

Debian has several types of installation images. This is a Netinstall image that contains only the most necessary components, complete images containing almost everything, as well as Live images with which you can start the system without installation.

To download the full image, open the repository page and download the first disk. Full images contain a huge set of Debian packages and are needed for installation on systems with poor Internet access. There are three images, but for installation you will only need the first. I wrote about installing from a full image in the article Installing Debian 9 since then, almost nothing has changed there.

In this article, we will perform installation from a live image. To download it, open this page and select an image with the desired environment. I will use gnome.

Step 2. Record an image on a USB flash drive

To write an image to a USB flash drive, you can use the utility Etcher, both in Windows and in Linux, you just select the image, then select the USB device and click Flush:

Step 3. BIOS Setup

The next step is BIOS setup, you need to restart your computer and press Del, Shift + F2, F2 or F8 to enter the BIOS setup interface. Find the Boot tab here. In the Bood Device Priority section, you must select Hard disk, and in Hard disk priority – install in the first place your flash drive:

All this works in a similar way both in the new BIOS and in the old ones, but in the new ones everything is much simpler. Debian installs perfectly on UEFI, so no additional configuration is needed.

Step 4. Choosing an installation option

As I wrote above, you have several installation options to choose from. You can boot into Live mode and install the system using Calamares or use the familiar Debian installer:

Step 8. Keyboard Layout

I advise you to choose English, and then add Russian in the system, otherwise you will not be able to configure mount points, and also enter a username and password:

Step 9. Disk Partitioning

As usual, there are several markup options. You can completely erase the disk and install the system, or split the disk manually. Consider the manual option:

Step 10. Partition Table

If you have an empty disk, you need to create a partition table first. To do this, click New Partition Table.

Then select the table format, in most cases you can choose MBR, but if you are installing the system on UEFI, it is better to use a more modern GPT:

Step 11. Creating the bootloader partition

This section will store the bootloader files and the kernel of the system. To create a section, click on Available space and press the button Create. Recently, the bootloader files began to take up a lot of space, so with a margin for this section it is worth allocating at least 1024 megabytes. The file system is ext4. Then select a mount point / boot.

Step 12. The root partition

Similarly, you need to create a root partition. The mount point is /, the file system is ext4, and the size is at least 10 GB, but better than 30-50 GB, so that it is definitely enough for all system files:

Step 13. Swap Section

The swap partition should be the same as the size of RAM if you want to use hibernation mode or, if you do not want, at least half of the RAM and at least four gigabytes. Here you need to select linuxswap file system:
