How to Fix Low Disk Space Issues on Ubuntu Linux While using Ubuntu Linux, you may encounter various issues caused by insufficient storage space.  Over time, the system may become slower, software updates may fail, or files may no longer be saved properly. 1. Why Disk Space Runs Out on Ubuntu Ubuntu is designed to manage storage efficiently, but disk usage can increase gradually due to several factors: Cached files created during system updates Log files that grow continuously over time Snap packages storing multiple revisions Unused packages and dependencies left behind Large user files accumulated in the home directory These files often grow unnoticed until the system begins to show warning signs. 2. Checking Current Disk Usage The first step in resolving low disk space issues is understanding the current storage situation . 2.1 Check Overall Disk Usage Run the following command in a terminal: df -h This command displays total disk size, used space, an...

Raspberry Pi OS Installation Process

Raspberry Pi OS Installation Process

Raspberry Pi OS Installation Process


The Raspberry Pi is a compact computer that allows users to learn the process of installing and configuring an operating system themselves. 

Raspberry Pi OS is the official operating system provided by the Raspberry Pi Foundation, and thanks to its strong hardware compatibility and stability, it is the most suitable choice for the majority of users.

1. What You Need Before Installation

Before starting the installation, prepare the following items:

  • Raspberry Pi board (Pi 4, Pi 400, Pi 5, etc.)

  • microSD card (recommended: 16GB or larger)

  • microSD card reader

  • A PC or laptop (Windows, macOS, or Linux)

  • Power adapter

  • Monitor and HDMI cable

  • Keyboard and mouse

The microSD card serves as the main storage device for Raspberry Pi, so using a reliable card is strongly recommended for stability.



2. Overview of Raspberry Pi OS Installation Methods

There are several ways to install Raspberry Pi OS, but the officially recommended and most user-friendly method is using Raspberry Pi Imager.

Raspberry Pi Imager simplifies the entire process by handling the following tasks automatically:

  • Downloading Raspberry Pi OS

  • Formatting the microSD card

  • Writing the OS image

  • Applying initial configuration settings

This approach significantly reduces complexity, especially for beginners.



3. Downloading and Installing Raspberry Pi Imager

3.1 What Is Raspberry Pi Imager?

Raspberry Pi Imager is the official image-writing tool developed by the Raspberry Pi Foundation. 

It provides a simple interface that allows users to select an operating system, choose a storage device, and write the image in just a few clicks.


3.2 Installing Raspberry Pi Imager

  1. Visit the official Raspberry Pi website and download Raspberry Pi Imager.

  2. Choose the version suitable for your operating system (Windows, macOS, or Linux).

  3. Install the application following the on-screen instructions.

Once installation is complete, launch Raspberry Pi Imager to begin.



4. Preparing the microSD Card

Raspberry Pi OS is installed directly onto a microSD card. 

If the card has been used previously, its contents will be erased during the installation process, so be sure to back up any important data beforehand.

Insert the microSD card into the card reader and connect it to your computer. 

Raspberry Pi Imager will automatically detect the connected storage device.



5. Selecting Raspberry Pi OS

After launching Raspberry Pi Imager, you will see three main options:

  1. Choose OS

  2. Choose Storage

  3. Write


Choosing the Operating System

Click Choose OS to view the available operating systems. Common options include:

  • Raspberry Pi OS (64-bit)

  • Raspberry Pi OS (32-bit)

  • Raspberry Pi OS Lite (Legacy, 32-bit)

For first-time users, Raspberry Pi OS (32-bit) is generally the best choice because it includes a graphical interface and essential applications.

6. Using Advanced Settings

Raspberry Pi Imager includes an Advanced Settings feature that allows you to configure basic system options before installation.

6.1 Accessing Advanced Settings

After selecting the OS, click the gear icon to open the Advanced Settings menu.


6.2 Common Advanced Options

  • Setting the hostname

  • Creating a user account and password

  • Configuring Wi-Fi credentials

  • Setting locale, language, and keyboard layout

  • Enabling SSH access

These options are especially useful for headless setups, where Raspberry Pi is used without a monitor or keyboard and accessed remotely from the start.


7. Writing Raspberry Pi OS to the microSD Card

Once all settings are configured, click the Write button. 

Raspberry Pi Imager will automatically perform the following steps:

  1. Download the selected Raspberry Pi OS image

  2. Format the microSD card

  3. Write the OS image to the card

  4. Verify the written data

The process typically takes only a few minutes, depending on internet speed and microSD card performance.



8. Inserting the microSD Card and First Boot

After installation is complete, safely eject the microSD card from your computer. 

Then proceed as follows:

  1. Insert the microSD card into the Raspberry Pi

  2. Connect the monitor, keyboard, and mouse

  3. Plug in the power adapter

Once powered on, the Raspberry Pi will automatically begin the boot process.



9. Initial Setup on First Boot

If you installed Raspberry Pi OS with Desktop, a setup wizard will appear during the first boot.

Initial Configuration Steps

  • Language and region selection

  • Keyboard layout confirmation

  • User account setup

  • Wi-Fi network connection

  • System update

After completing these steps, you will be taken to the Raspberry Pi OS desktop environment.



10. First Boot Experience with Raspberry Pi OS Lite

Raspberry Pi OS Lite does not include a graphical interface. After booting, the system displays a terminal login screen.

All configuration is performed using command-line tools. 

If SSH was enabled during installation, you can log in remotely without connecting a monitor. 

This version is commonly used for servers, automation systems, and headless environments.



11. Recommended Tasks After Installation

Once Raspberry Pi OS is installed, the following steps are recommended:

  • Update the system packages (apt update and apt upgrade)

  • Verify time zone and locale settings

  • Disable unnecessary services if needed

  • Create regular backups of the microSD card

These basic maintenance steps help ensure a stable and reliable Raspberry Pi environment.



12. Conclusion

The Raspberry Pi OS installation process is an essential step in understanding the Raspberry Pi environment and represents the first stage in learning how a Linux operating system works. 

By using Raspberry Pi Imager, the installation can be completed quickly and reliably without complex configuration, although alternative installation methods are also available. 

Users can simply choose the method that feels most comfortable for them.

Understanding Computer System In the digital age, computers have become essential tools used across many fields. A computer is built on two core components: hardware and software . Understanding how these two elements are structured and how they operate helps users manage and operate computers more effectively. 1. What is Computer Hardware? Computer hardware refers to the physical, tangible parts of a computer system.  These are the components you can touch and see.  Without hardware, a computer would have no structure to run programs or process data. 1.1 Main Types of Hardware Input Devices – Tools that allow you to send information to the computer. Examples: Keyboard, mouse, scanner, microphone. Output Devices – Components that deliver processed information to the user. Examples: Monitor, printer, speakers. ...

Understanding System Software The computer programs we use operate on top of an essential layer of software known as system software , which makes all tasks possible. System software manages hardware resources, provides an environment in which application programs can run, and plays a critical role in ensuring that the entire computer system functions smoothly and reliably. 1. What is System Software? System software is a set of programs designed to operate, control, and extend the processing capabilities of the computer itself.  Unlike application software, which performs specific user tasks, system software manages the hardware and provides a platform for applications. The main purpose of system software is to act as a bridge between the user applications and the physical hardware of the computer. 2. Types of System Software System software can be broadly categorized into several key types: 2.1 Operating System (OS) The operating system is the m...
