🧰 How to Install an OS on Raspberry Pi
✅ Method 1: Using Raspberry Pi Imager (Recommended)
- 🔽 Download Raspberry Pi Imager
- 💽 Insert your microSD card (16GB+)
- 🖱️ Select an OS (e.g., Raspberry Pi OS)
- 💾 Choose your SD card → Click “WRITE”
- 🔌 Insert card into Raspberry Pi and boot up
💡 Advanced: Press CTRL+SHIFT+X before writing to pre-configure Wi-Fi, SSH, and hostname.
🛠️ Method 2: Using Balena Etcher (For .img Files)
- Download
.imgof your OS from official sources - Open Balena Etcher
- Select image → Choose SD card → Click “Flash!”
- Eject safely and boot on Raspberry Pi
📝 Ideal for RetroPie, Ubuntu, or custom distributions.
🖥️ Post-Installation Tips
After booting for the first time:
| ✅ Action | 📝 Purpose |
|---|---|
| Set Locale & Timezone | Match keyboard & time to your region |
| Change Password | Replace default credentials for security |
| Update Packages | Run sudo apt update && sudo apt upgrade |
| Enable Interfaces | Via raspi-config (SSH, I2C, SPI, etc.) |
📌 GUI users will see a setup wizard; Lite users can run setup from the terminal.
🧪 Example: Boot Raspberry Pi OS and Run Python
Once on the Raspberry Pi desktop:
- Open Thonny IDE from Menu → Programming
- Enter:
print("Hello, Raspberry Pi!")
- Click “Run” to see your first script output!
