Hi, I am using ASUS U56E laptop, which came with Window 7, i installed Windows 8(3 month trial version). Now I am trying to install Ubuntu 12.10 using the bootable dvd. I changed my BIOS setting to boot from the dvd first and deleted all other priorities, but for some reason it says "Reboot and select proper Boot device or Insert Boot Media in selected boot devices and press a key" with a black screen. I must boot the dvd in order to install the OS, because when I tried to install it without booting the dvd, it doesn't install properly. Hope someone can help, would really appreciate your effort. Thank you.
