Booting Orange Pi 5 from NVMe SSD – Unixorn guide

✅ Step‑by‑step guide

1. Boot from microSD

Flash the official Orange Pi Ubuntu/Debian image (or Armbian) to an SD card.
Insert that card and the NVMe, then boot your board.

Powershell

type $env:USERPROFILE\.ssh\yourkey.pub | ssh user@ipaddress  "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

CMD

type %USERPROFILE%\.ssh\id_ed25519_tunnel.pub | ssh user@host "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

Pictured MOTD

Want your server to greet you with a nice picture (ASCII/ANSI art) when you SSH in? This guide shows how to generate different-width ASCII art pieces and automatically show the best-fitting one on login.

Prerequisites

A terminal that supports ANSI escape sequences (most modern terminals do).
SSH access to the server.
