I can see loading "xorg" and then blank screen with the systemd.unit=graphical.target added
My info before was on "run" on usb stick=endless reboots.
Problem Solved!
Jesus mother f... I looked in the kodi log i uploaded and it didnt detect my nvidia card, after some investigation it seems that the Z890 chipset has a fault, in some circumstances you need to "disable" internal graphics in bios to have the "operating system" detect that there is a external graphics card in the motherboard.
Jesus... i disabled internal grahpics and voila libreelec acts normal and functions .. woho.
Sorry to have bothered you guys with this. Thank you! for all your clues
Regards
