I'm trying to install Ubuntu (I've tried 12.04 Server, Desktop and 13.04 Desktop). I burn the image file to DVD, but on booting, all I get is the screen with the man in the circle and the keyboard, the DVD drive light flickers for a bit then I get the "no signal" message.
My system is: AMD A8-3850, 8Gb RAM, ASRock A75M mobo, Kingston 60Gb SSD and LG HD DVD/BluRay combo. If it matters, I am using HDMI out. Monitor is a Viewsonic 13".
