Hello! I bought on ebay the nas synology that won't start. If I connect you by VGA a monitor I see that it tries it from pxe because it does not find partition in the removable storage device usb that I attach in the image. Does anyone know where I can download the .img that will allow me to burn the original operating system? Thank you very much for your time. pd. if I install xpenology it seems that it works, but it configures as another model different from the one I have.
