A stable broadband connection (wired or wireless) will significantly improve your installation experience.

Before You Begin

Proper preparation prevents problems. Before starting the installation process, complete these essential preparatory steps.

Backing Up Important Files

CRITICAL WARNING: Installing an operating system can potentially result in data loss, especially if you're replacing your current system entirely. Always back up your important files before proceeding.

What to back up:

Where to back up:

Deciding Between Dual-Boot and Full Installation

You have two main installation options:

Full Installation (Replace Existing OS)

Dual-Boot Installation (Install Alongside Windows/macOS)

Understanding BIOS vs UEFI

Modern computers use two types of firmware systems:

BIOS (Basic Input/Output System)

UEFI (Unified Extensible Firmware Interface)

You don't need to be an expert on these systems, but knowing which your computer uses helps troubleshoot boot issues. Most computers manufactured after 2015 use UEFI.

Secure Boot is a UEFI security feature that prevents unauthorized software from running during startup. While Zorin OS supports Secure Boot, some users prefer to disable it during installation to avoid potential complications.

To check/disable Secure Boot:

  1. Restart your computer
  2. Enter BIOS/UEFI settings (usually by pressing F2, F10, F12, Delete, or Esc during startup)
  3. Navigate to the Boot or Security section
  4. Look for "Secure Boot" option
  5. Note whether it's enabled (you can disable it if experiencing boot issues)

Note: You can re-enable Secure Boot after installation if desired. Zorin OS is compatible with Secure Boot when properly configured.

Downloading Zorin OS

Now that your system is prepared, let's download the Zorin OS installation image.

Choosing Between Core, Lite, and Pro Versions

Visit the official Zorin OS website at zorin.com/os to download your preferred edition:

Zorin OS Core (Free)

Zorin OS Lite (Free)

Zorin OS Pro (Paid - €39)

For most beginners, Zorin OS Core provides an excellent balance of features and performance. If you're working with a computer older than 8 years, Zorin OS Lite is the recommended choice.

How to Verify Download Integrity

After downloading, verify that your ISO file wasn't corrupted during download:

For Windows users:

  1. Open Command Prompt
  2. Navigate to your Downloads folder
  3. Type: certutil -hashfile Zorin-OS-17-Core-64-bit.iso SHA256
  4. Compare the output with the SHA256 checksum listed on the Zorin website

For macOS users:

  1. Open Terminal
  2. Navigate to your Downloads folder
  3. Type: shasum -a 256 Zorin-OS-17-Core-64-bit.iso
  4. Compare the output with the official checksum

If the checksums match, your download is complete and uncorrupted.

File Size Expectations

Ensure you have stable internet during the download process. If interrupted, most browsers can resume the download.

Creating a Bootable USB Drive

To install Zorin OS, you'll need to create a bootable USB drive containing the installation files.
