I'm in my bios, then selected to boot from USB where the Ubuntu Mate 19.04 iso is. a GNU GRUB 2.02 menu appears with options:
Try Ubuntu Mate without installing
Try Ubuntu Mate without installing (safe graphics)
Install Ubuntu Mate
Install Ubuntu Mate (safe graphics)
Every option I choose, my screen goes black and does nothing. Feeling pretty helpless as there are basically no tutorials for this.
