[ubuntu] Installing Ubuntu 15.04

Im trying to install on an HP Notebook 17-p110nr.

After enabling "Legacy Support" and changing that boot order to "Inteal CD/DVD ROM Drive" as initial, I finally got GRUB to pop up. Then I went through the install and thought everything was good.

Now with Legacy Support still enabled, I changed the initial boot to "Notebook Hard Drive". When I boot up, I get "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key".

When I disable Legacy Support and boot up, it says "Boot Device Not Found Please install an operating system on your hard disk."

When I try to run the Live disk, the screen tus black.

Please help.

Thanks,

Adam E
