I have to install Ubuntu 12.04 LTS on 500 desktops. I want to know what is the better way to achieve this task. All the machines have same hardware WITHOUT NETWORK.

1Do they have local network? If yes I suggest using [PXE](https://en.wikipedia.org/wiki/Preboot_Execution_Environment). You can configure your own installation server, then via network install all system simultaneously – c0rp Jan 21 '14 at 13:11

1Are those 500 desktops the same? (same hard disc etc.) For maintanance: see puppet + puppermaster: https://help.ubuntu.com/12.04/serverguide/puppet.html (that will assume you installed it already though ;) ) – Rinzwind Jan 21 '14 at 13:12

@john I would still follow the 'dd'-copy answer in link I posted. All you need is a portable hdd with the 'dd' image on it. – Rinzwind Jan 21 '14 at 14:08
