1. Preparation
1.1. Backup Your Data Before making any changes to your system, it’s crucial to back up all your important data. Use an external hard drive, USB stick, or cloud storage service to ensure you have copies of your documents, photos, music, and any other important files.
1.2. Check System Requirements Ensure your computer meets the minimum system requirements for Ubuntu. These typically include:
- A 2 GHz dual-core processor or better.
- 4 GB of RAM (8 GB recommended).
- 25 GB of free hard drive space (50 GB recommended).
- Either a DVD drive or a USB port for the installation media.
1.3. Download Ubuntu Go to the Ubuntu website and download the latest version of the Ubuntu desktop ISO file.
1.4. Create Installation Media You’ll need to create a bootable USB stick or DVD from the downloaded ISO file. Use tools like Rufus (for Windows) to create a bootable USB drive:
- Insert your USB drive.
- Open Rufus.
- Select the Ubuntu ISO file.
- Click "Start" to create the bootable drive.
2. Installation

- Something else: This option allows for manual partitioning and is recommended for advanced users.
2.5. Partitioning If you choose "Something else," you’ll need to manually create partitions. A typical setup involves:
- Root (/): 20-30 GB.
- Home (/home): The remaining space for user files.
- Swap: Equivalent to your RAM size, up to 32 GB.
2.6. User Information Enter your personal details, including your name, computer name, username, and password. These will be used to create your primary user account.
