How to restore Dell M3800 Developer Edition

How do I completely restore Ubuntu to factory on the Dell M3800 Developer Edition? I know that there is some Dell Recovery Linux Tool, but how do I even access it?

On the bootloader there is an option to reset to factory settings. Assuming that you didn't also break the bootloader, you should be able to still do this. Once you turn on the computer as soon as you get the purple screen press the Esc key, this will show you some options for booting, and one of them should be something like "Reset to Factory Settings".

Ubuntu on Dell Precision M3800

The Dell driver download webpage for the Dell Precision M3800 Workstation only has drivers for Windows 7 and Windows 8.1. The following results are found at the Ubuntu on Dell Precision M3800 webpage at the official ubuntu.com website. The Dell Precision M3800 Workstation that has Ubuntu 14.04 preinstalled ships on pre-configured hardware, so you do not get the same choice of hardware options that you get on the Dell Precision M3800 Mobile Workstations that ship with Windows preinstalled. If your laptop has Ubuntu 14.04 preinstalled, it is supported by updates until April, 2019, so you don't need to upgrade or reinstall the operating system for a long time.
