Introduction

Welcome, intrepid explorer, to the world of PureOS! If you’re tired of walled gardens, proprietary shackles and endless “Are you sure you want to proceed?” dialogs from Big Tech, you’ve come to the right place. This guide will walk you through every detail—down to the occasional joke—to install PureOS, a privacy-respecting, free-software Linux distribution maintained by Purism.

System Requirements

Before we dive into the installation waters, make sure your hardware can handle PureOS’s awesomeness:

Pro tip: More RAM = fewer tears when compiling that obscure piece of open-source software. 😉

Step 1: Download the PureOS ISO

1. Visit the official PureOS downloads page: https://pureos.net/download/.
2. Choose either the “Basic” or “Full” image. The Basic image is lean and mean the Full image comes bundled with extra apps.
3. Click ‘Download’ and wait. Grab a coffee, stretch, or compose an epic limerick while the ~2 GB ISO dribbles onto your drive.

Step 2: Create a Bootable USB Drive

Time to channel your inner digital alchemist and transmogrify that ISO into a live USB stick.

Option A: BalenaEtcher (Cross-Platform)

• Download BalenaEtcher from https://www.balena.io/etcher/.
• Install and launch it. It looks pretty it also works flawlessly.
• Select the PureOS ISO, pick your USB drive, and hit ‘Flash!’
• Wait for the progress bar to reach 100%. No more coffee breaks—we’re almost ready!

Option B: Rufus (Windows Only)

• Download Rufus from https://rufus.ie/.
• Plug in your USB drive, open Rufus, choose the ISO, leave defaults (unless you love adventure), click ‘Start’.
• Confirm warnings about data destruction (make sure you have backups!).

Note: All data on the USB drive will be erased. So if you had grandma’s secret cookie recipe there, make a copy first.

Step 3: Boot from USB

1. Shut down your computer completely.
2. Insert the USB drive.
3. Power on and press the appropriate key to access your boot menu (F12, Esc, F10, Del, or the artist’s chosen key—consult your motherboard docs).
4. Select your USB drive and hit Enter.

If you see the PureOS logo and a friendly penguin doing cartwheels, you’ve succeeded. If not, try again or consult tech support (a.k.a. the Internet).

Step 4: Live Session and Partitioning

Try Before You Install

PureOS can run as a “live session” without touching your hard drive. Perfect for skeptics who fear commitment.

Partitioning Wisdom

Once you’re comfortable, click ‘Install PureOS’. You’ll be guided through partitioning:

• Automatic mode: Let PureOS carve up your disk.
• Manual mode: For power users who dream in ext4, swap partitions, and GPT/MBR configs.

Suggested layout (using manual mode):

• /boot partition: 512 MB, ext2/ext4, BIOS or EFI flags set.
• / (root) partition: ≥ 20 GB, ext4.
• swap partition: Equal to RAM (if you plan on hibernation).
• /home partition: The rest of the space, ext4.

Step 5: Running the Installer

1. Select your language, keyboard layout, time zone—relatively uncontroversial choices.
2. Load the partition table you set up, confirm formatting, and click ‘Install Now’.
3. Enter your real name, computer name (no profanity, please), username, and a strong password. Hint: “1234” is not strong. “CorrectHorseBatteryStaple” is stronger.
4. Kick back. The installer will copy files, install the kernel, grub, and a bounty of Free Software.

Bonus tip: If installation seems to hang at 99%, don’t panic. It’s just the installer taking a final, thoughtful breath.

Step 6: First Boot and Post-Install Setup

1. Remove the USB drive and reboot.
2. Grub will present you with PureOS. Hit Enter.
3. Log in with the user credentials you created earlier.

Congratulations! You’re now in a privacy-focused wonderland. But wait—there’s more:

Update Your System

sudo apt update  
sudo apt upgrade

If prompted to restart, do so—you’ll feel like a brand-new system.

Install Favorite Software

• Firefox: Already here, because privacy.
• LibreOffice: sudo apt install libreoffice.
• GIMP: sudo apt install gimp (for pixel-mashing madness).
• VLC: sudo apt install vlc (for all your video-watching prowess).
• Flatpak support: sudo apt install flatpak flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo.

Tips, Tricks Troubleshooting

Wi-Fi Won’t Connect?

Check the top-right network icon. If your driver is missing, use a tethered ethernet or USB tether via your phone and run:

sudo apt update  
sudo apt install firmware-linux

Display Issues

If you see a black screen, append nomodeset to the GRUB boot line:

1. At the GRUB menu, press ‘e’.
2. Find the line starting with linux and add nomodeset before ‘quiet’.
3. Press Ctrl X to boot.

Conclusion

You’ve journeyed through ISO downloads, USB creation, partitioning labyrinths, and the sacred rites of sudo apt upgrade. Now you stand victorious with PureOS fully installed—your fortress of privacy and freedom.

Celebrate responsibly: maybe a bowl of popcorn, some healthy glow from your new desktop, and a deep sigh of relief. You’ve earned it!

Happy computing—and may your digital footsteps remain untracked!
