I have a used Lenovo NAS ix2-NG without disk when I connected it to PC I was not able to access it through LAN cable, I came to know that its firmware/OS was on the installed HDD. To setup this drive i have to copy its firmware/OS to new HDD that I'm going to install. I was not able to find any useful information or walkthrough on the internet.
I'm using windows 10 OS to setup this drive, please if anyone can help, how can i copy its firmware/OS to get start on this.
On some forums I read may be it uses Linux OS? i setup VM on my windows computer with Ubuntu that may help or i also have Raspberry Pi I can get help to update firmware on NAS drive.
Edit 1: I forgot to mention that I also tried to access through router.
Edit 2: some links regarding the issue
