Installation of Debian 10 (Buster) Guide

1. To install Debian 10 Buster directly onto your computer’s hard disk, you need to obtain the Debian 10 installation image(s) which may be downloaded by going to Debian on CDs.

  1. Download Debian 10 ISO Images

2. Once you have downloaded the Debian CD and DVD images, create a bootable USB stick or burn it on a CD, or DVD using any software such as BootisoGnome Disk UtilityLive USB Creator and many others.

3. After creating a bootable media (USB stick or DVD), place it in the correct drive, reboot the machine and tell the BIOS/UEFI to boot-up from the DVD/USB by pressing a special function key (normally F12F10 or F2) to open the boot menu. Then select your boot device from the list of devices and click Enter.

4. Once the installer boots, you will see the Installer menu (BIOS mode) that provides several options for installation. Select Graphical Install and click Enter.

5. Next, choose the language to be used for the installation process. Note that the language you select will also be used as the default system language. Then click Continue.

Select Debian Installation Language

6. Then select your location (country) which will be used to set the system time zone as well as locales. You can find more countries under others if yours doesn’t appear in the default list.

Select Your Location

7. After that, if there is no locale for the language and country combination you selected, you have to configure the locales manually. The locale used is in the second column (e.g en_US.UTF-8).

Configure Locales

8. Next, configure the keyboard by selecting the keymap to use. Remember that this affects the key-meaning associations of your computer’s keyboard.

Configuring the Network

9. If you have multiple network interfaces, the installer will ask you to select the one to use as the default/primary network interface. Otherwise the first connected network interface is selected.

Then click Continue to configure all network interfaces attached to the system to obtain an IP address using DHCP.

Select Primary Network Interface

10. Next, set the hostname (archaically nodename, e.g tecmint1) for the system. This name helps to identify your system to other devices/nodes on a network.

Set Hostname

11. Once the hostname is set, also set the domain name (e.g tecmint.lan). The domain name should be the same on all other nodes on your network. In this case, the systems Fully Qualified Domain Name (FQDN) will be tecmint1.tecmint.lan.

Set Domain Name

Creating User Accounts and Passwords

12. It’s now time to create user accounts. First, create a user account for non-administrative activities. This user can be configured to gain root privileges using sudo. Enter the new user’s full name and click Continue.

Create Normal User

13. Next, create a username for the above user. Do not forget that the username must begin with a lower-case letter followed by a combination of numbers and more lower-case letters.

Create Username for Normal User

14. Set a strong and secure password (made up of a mixture of letters both lowercase and uppercase, numbers, and special characters) for the new user account. Confirm the password and click Continue.

Partitioning Disks for Debian Installation

15. Now it’s time prepare the storage disk(s) before any file system is created on it during the actual installation of system files. There are several disk partitioning options but we will use Manual partitioning. So select it and click Continue.

Select Manual Partitioning

16. The installer will display all currently installed disks (or configured partitions and mount points as well) on your computer. Select the disk you want to partition (e.g 34.4 GB ATA VBOX HARDDISK which is unpartitioned) and click Continue.

Select Disk to Partition

17. If you have selected an entire disk, the installer will show a warning message. Once you have decided to partition the disk, select Yes to create a new empty partition table on the disk and click Continue.

Accept to Partition Disk

18. A new empty partition table has been created on the disk. Double click on it to create a new partition.

23. From the previous interface, double click on the free space (4 GB in this case), go through the same steps we used to create the root partition. Click Create a new partition, enter its size, then set it as a Logical partition and configure it to be created at the end of available space.

Select Free Space to Create Swap

24. At the partition settings interface, set Use as value as swap area (double click on the default value to get more options). Then go to Done settings up the partition to continue.

Select Debian Mirror

At this stage, the installer will try to configure the APT package manager to use the above Debian archive mirror, and it tries to retrieve a number of packages. Once that is done, the installation process will proceed.

30. Also, configure whether to participate in the package usage survey. You can modify your choice later on using the “dpkg-reconfigure popularity-contest” command. Select Yes to participate or No to continue.

Install Collection of Software

31. Next, select the predefined collection of software to install along with the base system files. For this guide, we will install Debian desktop environment, Xfce, SSH server and standard system libraries. You can choose the desktop environment of your choice if you want to install one.

If you intend to set-up a server on a computer with a small amount of resources such as RAM, you can de-select the Debian desktop environment and ...Xfce options to avoid installing them (refer to the system requirements) Then click Continue.

Software Selection

32. Last but not least, tell the installer to install the GRUB boot loader by selecting Yes from the following interface. Then click Continue. Then select the bootable device on which GRUB will be installed, and click Continue.
