Introduction
Welcome, intrepid explorer of open‐source realms! You’re about to embark on a quest to install Ubuntu Linux, the user‐friendly penguin-powered operating system that even your grandma could love (if she weren’t already hooked on Sudoku). Whether you’re escaping the tyranny of proprietary software or simply curious about the command line, this guide has you covered. Strap in, grab a cup of something caffeinated, and let’s dive into the land of terminal prompts and apt-get magic.
Prerequisites
- A computer with at least 2 GB RAM (4 GB or more recommended).
- Minimum 25 GB of free disk space (go big or go home!).
- USB flash drive (4 GB or larger) or blank DVD.
- Reliable internet connection for downloading the ISO and updates.
- Basic familiarity with BIOS/UEFI settings (fear not, we’ll guide you).
System Requirements at a Glance
| Component | Minimum | Recommended |
|---|---|---|
| CPU | 1 GHz single-core | 2 GHz dual-core or better |
| RAM | 2 GB | 4 GB |
| Disk Space | 25 GB | 50 GB |
| Graphics | VGA capable | OpenGL 3.0 |
| Network | Ethernet or Wi-Fi | 100 Mbps or faster |
1. Downloading the Ubuntu ISO
Head over to the official Ubuntu website:
https://ubuntu.com/download/desktop
- Select the latest Long Term Support (LTS) version for stability or the standard release for cutting-edge features.
- Click Download and wait. This might take a while unless you have warp-speed Internet (or live next to a data center).
- Verify the checksum if you enjoy feeling extra safe. Compare the SHA256 hash of your ISO to the one on the site.
2. Creating Bootable USB/DVD
On Windows
- Download Rufus.
- Insert your USB flash drive.
- Open Rufus, select the Ubuntu ISO, and click Start.
- Wait for it to finish. Beware: your USB’s data will disappear—make backups!
On macOS
- Install balenaEtcher (link).
- Run Etcher, choose the Ubuntu ISO and your USB drive, then click Flash.
On Linux
- Open a terminal.
- Use dd (be very cautious with drive identifiers):
sudo dd if=~/Downloads/ubuntu.iso of=/dev/sdX bs=4M status=progress sync
3. Booting into the Live Session
Time to reboot:
- Access your BIOS/UEFI by pressing F2, Del, Esc, or F12 (model dependent).
- Set the USB/DVD drive as first in the boot order.
- Save and exit. If you hear triumphant penguin cries, you’re in the right place.
You’ll see a menu offering Try Ubuntu or Install Ubuntu. Selecting “Try” lets you explore without changes “Install” takes you through the wizard.
4. Installing Ubuntu
4.1 Language, Keyboard, and Updates
- Choose your language (English, Klingon, or Elvish if available).
- Pick keyboard layout. You can even enable “Show keys to preview layout.”
- Decide whether to install updates and third‐party drivers. Tip: check both for a smoother ride.
4.2 Disk Partitioning
Your options:
- Erase disk (all data gone—use only on sacrificial PCs).
- Install alongside (dual‐boot Windows or another Linux distro).
- Something else (fully manual: create / (root), swap, /home partitions).
Manual Partitioning Example
| Partition | Mount Point | Size | Type |
|---|---|---|---|
| / | root | 20 GB | ext4 |
| swap | swap | 4 GB | swap area |
| /home | home | rest of disk | ext4 |
4.3 User Setup and Time Zone
- Enter your name, PC name, username, and a strong password.
- Select your time zone on the map (mountain time or mermaid time, your choice).
4.4 Let the Installer Do Its Thing
Hit Install Now and watch the progress bar meander merrily. Grab another snack.
5. Post‐Installation Steps
5.1 First Boot
- Remove the USB/DVD when prompted and reboot.
- Login with your new credentials.
5.2 Update amp Upgrade
Open Terminal (Ctrl Alt T) and run:
sudo apt update sudo apt upgrade -y
5.3 Install Essential Software
- Browsers:
sudo apt install firefox(or chromium). - Media codecs:
sudo apt install ubuntu-restricted-extras. - Productivity:
sudo snap install libreoffice.
5.4 Enable Additional Drivers
Go to Software amp Updates gt Additional Drivers to install proprietary GPU or Wi-Fi drivers.
6. Troubleshooting amp Tips
Cannot Boot from USB?
- Check BIOS for Secure Boot—disable if it blocks Ubuntu.
- Try another USB port or recreate the media.
Stuck at ‘Grub Rescue’?
- Boot the Live USB, open Terminal, and run:
- If that fails, use Boot-Repair:
sudo add-apt-repository ppa:yannubuntu/boot-repair sudo apt update sudo apt install -y boot-repair boot-repair
sudo update-grub
Performance Feels Sluggish
- Install
tlpfor power management:sudo apt install tlp. - Use a lightweight desktop:
sudo apt install lubuntu-desktop.
