1. Open Media Vault Backup

In this article, I am going to show you how to download OpenMediaVault ISO file, make a bootable USB thumb drive of OpenMediaVault and install it on your computer. OpenMediaVault (OMV) is an open source NAS (Network Attached Storage) operating system.

1. 2) Prepare the Boot Media. The ISO image can be used to install OpenMediaVault into a virtual machine like VMWare or Virtualbox directly. To install the software on real hardware, you need a boot media like a CD / DVD or a bootable USB stick. Burn the downloaded ISO file on a CD or DVD or load it on a USB stick. 2.1) Create a bootable USB Stick.
2. I believe the issue is that commodity USB sticks tend to have a relatively short lifetime when subjected to the rigors of being a boot disk. You could always try it, but they often die after just a few months.

Open Media Vault Backup

OMV can be installed on a Flash drive to boot from it. Step 1: Follow the 'install OMV to a Drive' method and select your USB-Flash-drive as target drive. Step 2: Enable the openmediavault-flashmemory plugin. This lowers the amount of writes to the USB Flash Drive, making sure you can enjoy it for a long time. Warning when using older OMV versions (before 3.0) You might get a WARNING near the end of the installation: 'Unable to install GRUB to /dev/., This is a fatal error'. This is a known bug in 2.x and is fixed in the upcoming 3.x. If you see this error message, then at this point unplug the OMV Installer USB drive (NOT your target USB drive).

It is no longer needed to complete the install. Now, select and enter.

You will be present with a list of install steps. Choose 'Install GRUB.' And continue with the remaining install process.
