Installation Guide

This guide provides step-by-step instructions for installing Oreon Linux on your computer. We recommend reading through the entire guide before starting the installation process.

Before You Begin

  • Download the ISO: Obtain the latest Oreon Linux ISO image from the Downloads page.
  • Verify the ISO (Recommended): Ensure the downloaded ISO file is not corrupted by verifying its checksum (SHA256 or similar). Checksum details are usually provided alongside the download link.
  • Create Bootable Media: Write the ISO image to a USB drive (recommended, 4GB minimum) or DVD. Tools like Rufus (Windows), balenaEtcher (Cross-platform), or the `dd` command (Linux/macOS) can be used.
  • System Requirements: Ensure your computer meets the minimum system requirements (check the specific release notes for details, but generally: 64-bit processor, 4GB RAM, 25GB disk space).
  • Backup Data: Back up any important data from the target computer before proceeding. The installation process may erase the hard drive.
  • Configure BIOS/UEFI: Access your system's BIOS/UEFI settings (usually by pressing F2, F12, DEL, or ESC during boot) and configure it to boot from the USB drive or DVD you created. Oreon Linux supports Secure Boot, so disabling it is typically not required. Ensure UEFI mode is enabled.

Booting the Installer

  1. Insert the bootable USB drive or DVD into your computer.
  2. Restart the computer.
  3. If configured correctly, the Oreon Linux installer boot menu should appear. Select the option to "Test and run Oreon Linux" (or similar) and press Enter.
  4. The installer environment will load. This may take a few moments.

The Anaconda Installer

Oreon Linux uses the Anaconda installer, common in RHEL-based distributions. The main screen presents a summary of installation options.

Anaconda Installation Summary

You need to complete items marked with a warning icon before proceeding. Click on each section to configure it:

1. Language Selection

Choose your preferred language for the installation process and the final installed system. Click "Continue".

2. Keyboard Layout

Verify or change the keyboard layout to match your hardware. You can test the layout in the provided text box. Click "Done".

3. Time & Date

Select your geographical region and city to set the correct timezone. Ensure "Network Time" is enabled if you have an internet connection for automatic time synchronization. Click "Done".

4. Installation Destination

This is the most critical step where you configure disk partitioning.

  • Select the target hard drive(s) where you want to install Oreon Linux.
  • Under "Storage Configuration", choose either:
    • Automatic: Recommended for most users. The installer will attempt to automatically partition the selected disk(s). You can choose to reclaim space if necessary.
    • Custom: For advanced users who want to define partitions manually (e.g., separate /home, LVM, specific filesystems).
  • If you choose Automatic partitioning, you can review the proposed layout. Ensure it doesn't conflict with other operating systems if you are dual-booting.
  • Click "Done". If you made changes that require formatting, Anaconda will ask for confirmation.

Begin Installation & User Creation

  1. Once all items on the installer are configured (no warnings), you can begin the installation.
  2. The installation will continue copying files and configuring the system. This can take some time depending on your hardware and software selection.

Finishing Up

  1. When the installation is complete, click the finish button.
  2. Reboot your computer and remove the installation media (USB drive or DVD) after the reboot is complete.
  3. Your computer will restart and boot into your new Oreon Linux system.
  4. Log in using the user account you created during installation.

Congratulations! You have successfully installed Oreon Linux. Proceed to the Post-Installation Setup guide for initial configuration and updates.
