Hi Steve, The version is Lubuntu 15.4. When I tried to upgrade this OS, a message appeared saying "to old for upgrade. Install the version 15.10". So I will download Lubuntu 15.10 and give a try. "Nvidia pilot" means "Nvidia driver", yes indeed. I took some pictures of the error messages appearing during the installation. The only working installation was the Lubuntu 15.4. To get there, I erased the four SSD disks (after removing the RAID0 from the BIOS). Then I formatted the SSD disk0 with the option "bootable" activated. Each other installation (like the Ubuntu 20.04) done on top of this first installation failed. I tried the two options: "install aside of the previous OS" and "Replace previous OS".
