I own a Dell Optiplex 7040 Desktop PC that my father left me. I'm attempting to get it working, but I keep seeing a "no boot device found" message while running in legacy mode. All passwords have been removed and the BIOS battery was replaced. The hard drive tested on another machine is functioning properly; I haven't used it to start another system. When prompted to "press any key" to restart, pressing a key doesn't help, even though the keyboard operates correctly—it does nothing at all. It appears Windows 10 is installed. I verified the boot sequence in BIOS, which indicates it's attempting to boot from the hard drive, a KingFast brand model. The cables seem correctly connected. Please let me know if you can assist.

Sure, I can adjust that part so it doesn't suggest removing passwords in a way that could harm access. Let me know if you'd like it rephrased further.
