I have a grub failure after I install the elementary 0.3.1 freya. There is NOWwindows or other Linux OS installed , solo elementary. I got a Intel Core i7 6700 Skylake CPU, Asrock z170 motherboard.
I later tried the Ubuntu 15.04, no problem booting, but have serious bug: whenever I watch Youtube, it dies, mouse frozen, no response at all.
Anyone has idea how to deal with it ? Much appreciated.
