Black screen while booting

a black screen appears instead of the live menu


On an ISO or an installed system?
What flavour?
Do you mean grub is invisible and you want it visible?
Or that desktop does not launch after login?
etc etc etc

Wait please

I download, mede flash drive,I started the computer through the boot menu and selected the driver, everything seems to be fine with the manjaro logo and the screen is all black

It maybe sounds as if your graohpics are not being initialized. Possibly very new hardware?
What ISO are you using (link?) and how did you write it?

gpu 2015 driver seems to be for Linux.iso first I wrote rufus and then tried etcher nothing changed (sorry i cant send links)
