Debian13.0 : OS Install

1.Overview of Debian13

In this article, we will explain how to build a server with Debian, the basis of the user-friendly Linux distribution UBUNTU. The latest is the stable Debian 13 "Trixie" released on August 9, 2025.

2.Download Debian13.0 installation image

Go to the official Debian website https://www.debian.org/ and download debian-13.0.0-amd64-netinst.is

Burn the iso image saved above as a boot disk to CD or USB using your favorite writing software.

3.Debian13.0 INSTALL

Change the BIOS so that the PC can boot from the installation disk created above.

3.1.Installation screen

Select "Graphical install" from the screen that appears.

3.2.Select installation language

Select the default "English" and click "Continue".

3.3.Select Location

Select [other] [Asia] [Japan]

3.4.Language Selection

3.5. Keyboard Settings

Configure the keyboard settings for use with the system. Select the keyboard of the language you wish to use from the keymap to be used.
In this case, select "Japanese".

3.6. Network Settings

Since a fixed local address cannot be specified at the time of Debian13 installation, and the network environment is assumed to have a DHCP server running, the IP address settings are done automatically. A fixed IP address can be specified from the command after installation.

3.6.1. Hostname Configuration

Set the hostname for your Debian system. The default is "debian", but you can change it to any name you prefer.

3.6.2. domain name

Set the domain name. The setting value is optional.

3.7. User and Password Setup

3.7.1 Setting the root password

Set the password for the system administrator (root user).
root has full access to the system. Enter the password in the "root password" field displayed on the screen.

3.7.2 General User Settings

After setting the root password, proceed to configure a regular user account (non-administrator privileges) for non-root operations. Enter the user's full name. "huong" is being entered.

Enter your user account name (any name)

Set the password for the created user.

3.8. Disk Partitioning

3.8.1 Disk Partitioning

Configure the disk partitioning (logical division) for installing the Debian system. There are four partitioning methods:

This time, we will use "Use entire disk".

3.8.2 Selecting a disk

Select the disk to partition. Disks available for installing Debian will be displayed. Since this is a single disk, the displayed disk is automatically selected. (This installation is on VMware Workstation, so the display differs from the standard view.)

3.8.3 Configuring Automatic Partitioning

Select how to partition the selected disk. This time, choose "All files on one partition (recommended for novice users)". If you select one partition, it will consist solely of the "/(root)" partition.

A summary of the partition will be displayed. If acceptable, write permission will be granted.

3.8.4 Confirming writing to disk

A final confirmation will be displayed before partitioning. Select "Yes".

3.9. Base System Installation

3.10. Package Manager Configuration

3.10.1 Verifying CDs/DVDs Managed by the Package Manager

Verify the CD/DVD used for installation. You can also inspect any additional disks used by the package manager. NETINST provides the minimal configuration, with additional components downloaded from the Internet, so select "no" here.

3.10.2 Selecting an Archive Mirror

An archive mirror is similar to a CentOS repository, serving as the source for obtaining packages via apt. It selects the geographically closest location for downloading software over the network. Since this system is deployed in Japan, select "Japan".

Select the optimal location from the Debian archive mirrors located in Japan. Select "ftp.jp.debian.org".

3.10.3 Proxy Settings

If you are connecting to the Internet via a proxy server, configure the proxy server settings here. Since we are not using one this time, skip the configuration and click "Continue".

3.11.Popularity Contest Settings

Popularity Contest is a system that anonymously provides statistics on used packages to Debian developers. This feature is used as a reference for future package design in Debian distributions. Feel free to set "No" or "Yes" as you prefer.

3.12. Software Selection

This screen allows you to select the Debian software to install. Since we are not installing a desktop environment this time, select the following two options:
SSH server
Standard system utilities

Software installation will begin.

3.13. Install the bootloader

If there is only one OS installed on the hard disk, install the boot loader.
Since no other OS is installed on the hard disk in this environment, select "Yes" for "Install the GRUB boot loader to the boot drive?".

Select the boot loader installation destination. Typically, the destination is displayed automatically, so manual selection is not required. Here, select the displayed "/dev/sda".

The installation will continue, and once it finishes, the next screen will appear.

Debian 13 has now been installed on your system. Click "Continue" to begin rebooting the system.。
Remove the installation media, then restart your computer after verifying in the BIOS that it boots from the installed disk (HDD or SSD). The login prompt will appear. This completes the system startup process.
