OpenMediaVault (OMV) is open-source NAS software based on Debian and designed to make it easy to build a NAS.

This article explains how to install OpenMediaVault.

# Introduction

For the server hardware, GMKtec’s NucBox M5 Plus was selected.

Since the Proxmox VE virtualization platform is installed on the mini PC, a virtual machine is created there and Debian is installed on it.

When installing it in a virtual machine on Proxmox VE, also see Create a Virtual Machine (VM) on Proxmox VE.

# Download OpenMediaVault

Download the ISO image from the OpenMediaVault download page. In this example, OpenMediaVault 7.4.14 was downloaded.

Write the downloaded ISO image to a USB drive. Use an image-writing tool such as Win32 Disk Imager.

For details on using Win32 Disk Imager, see How to Install and Use Win32 Disk Imager.
