I have an old N40L with 16GB of ram, 240GB SSD and 4x14TB Exos drives. I believe the bios is standard.
I've having trouble installing unraid. I get a black screen after the initial system checks. If I do the make bootable script then I get "Non System Disk - Press any key to reboot.". I can boot Linux Lite fine via USB.
Here's a list of things I've tried
The USB creator on both Windows and Mac.
Two different sticks: a 16GB Corsair Survivor and a brand 128GB Kingston
Legacy boot script
Different USB sockets including internal
Change boot order to USB First
Installing a Debian LiveISO via rufus with extra support for legacy bios, then replacing the files with Unraid manual install files.
Tried with all the drives disconnected
Any ideas?
