I connected it as well to the USB port on the side of the laptop, and it made no difference. Are there any sources I can use that can be provided to help fix this problem? From: Silas on 06/12/2015 Hello everyone, My name is Silas and I have a Dell Inspiron M5040 laptop. I successfully replaced the hard drive, however this annoying error keeps coming up: Intel UND1, PXE-2.1 (build 083)Copyright (C) 1997-2000 Intel Corporation This product is covered by one of more of the following patents: x Realtek PCIe FE Family Controller Series v1.24 (10/07/10)PXE-E61: Media test failure, check cable PXE-M0F: Exiting PXE ROM.
