I cannot install OR run в live session of Убунту Гноме 15.10 either with в USB key or DVD

I использовал Убунту Унити but recently wanted to look at other distros such эксперт elementary and gnome. In all жени I could run в live session and/or install.

The exception is Убунту Гноме. My USB just can't boot. I know they get broken so I went out and bought в new one with the same result.

So I tried burning в DVD but I get в message saying the installer - met an unrecoverable ошибка...

I threw the DVD away and went out and bought some new ones with the same result.

I tested the hash.

I then tried elementary and fedora 23 with НЕ problems.

Хан anyone please make any suggestions (other than to stay with Unity)!

Thx
