The Dell OEM Recovery Tool is what is used to obtain system images.  This requires your service tag in order to validate what OS the system shipped with before it will allow you to download image to a USB device for imaging purposes. Reference: Reinstall Linux | Dell US
Hi All, I have recently purchased a Dell XPS 9380 with Windows 10. I would like to install Ubuntu (dual-boot) on this system. This page shows me that 18.04 LTS 64-bit with the 4.15.0-1027-oem kernel is certified for this machine. Could someone tell me where I can download the OEM images from please? I would also be interested to know the package manager URLs for any Dell specific/OEM packages that I might need - e.g. for the touchpad. Kind regards!
