Hi,
I don't know what I did, but my NUC now will not enter BIOS setup (F2). I disconnected everything but a monitor and keyboard. NUC connected with DP to HDMI adapter, then directly to TV. power on, and TV says no signal. unplug and plug the cable, and now I get "Checking Media Presence..." followed by "bootable device has not been detected". I install a bootable USB drive, and get nothing but a blank screen. Last thing I did in BIOS, before all this, was to disable legacy boot. That's it. And now its basically a brick. I have tried "BIOS Security" jumper (yellow jumper) to no avail; when I do that, the screen stays blank forever. The NUC is clearly doing *something* because the keyboard numlock light can toggle. But that's not very useful when I want to run a HTPC. Last week, this entire system worked fine. I shut it off for the weekend, and came back to a corrupted SSD. Reinstall the OS, and now it's dead. Can't find any documentation to guide me. Need some help, please.
