Hi I am running the hp n54l proliant and was running 5.2 for many years. I decided to update to the 6.1 using Juns guide. After many failed attempts I realised I need to update the bios which I did. After installing the bios 6.1 was being found on the Lan. But only at first boot. After going through fresh install or migrate the system reboots and Lan is not found after that. I am struggling to find out what it could be. I have tried to do a fresh install on a new HDD but still the same issue. Re
