I've ordered a Dell PET40 with no OS and I've also ordered Server Essentials 2019 both from Dell. I can't seem to get the OS to install through several different methods. I've set the BIOS to UEFI and burned my ISO in UEFI mode, when I start the install with that method, I get the error stating "Your computer is missing drivers...". I then tried re-burning the ISO to BIOS mode and set my settings on the server to go into BIOS mode but the installation just hangs on the spinning windows dots and never proceeds.
All of the documentation I can find refers to using LifeCycle Controller to install the OS, but I don't know how to get into LifeCycle controller on this server. I also don't even know if this T40 has LifeCycle controller capabilities.
