I finally got it working by injecting the I219-LM driver from Intel: https://downloadcenter.intel.com/download/22283/Intel-Ethernet-Connections-CD Since I wasn't sure which driver would work I deleted all x32 and Linux folders and only imported the Winx64 drivers from these folders:PROXGB, PRO1000, PRO40GB, PLATFORM, NVMUupdatePackage, APPS. One of these folders contained the right driver but I'm not sure which one as I didn't have the time to thoroughly test each one. The bios also had to be changed to UEFI w/Legacy enabled, SATA on AHCI, Secure boot disabled and FastBoot set to Auto. This worked for both Latitude E7470 and E7270 models.
