Hi guys! I have custom made desktop computer on MOBO Gigabyte Z390 UD that has WIN7 (drivers for USB are from WinRaid forum) and WIN 10 on separate SSD's. Selection of OS is via BIOS so there is no OS interference. Today I have to reinstall WIN 7, but now it is impossible to install Realtek LAN driver, during setup message appear: "Network Controller was not found".

The strange thing is that WIN10 runs normally on same network controller. All drivers I have installed for WIN7 are same as they were before. I have tried all the solutions I have found on internet, without any success. Any ideas what it might be?
