I'm trying to dual boot Ubuntu 12.10 with my current Windows 8 install, but the Live CD gives a black screen with a blinking underscore (no errors or anything, just blank) when I select "Try Ubuntu." I've disabled Fast Boot in my BIOS, Secure Boot is off, and I've tried all of the F6 options, and still nothing has worked. I've also tried both UEFI and legacy booting the Live CD. I have no idea why it's not working.
Intel Core i5-3570K 3.4GHz
Asus P8Z77-V PRO
Samsung 8GB (2 x 4GB) DDR3-1600
Western Digital Caviar Blue 1TB 3.5" 7200RPM HDD
Crucial M4 128GB 2.5" SSD
Gigabyte Radeon HD 7970 3GB
Note: I've only tried the 64-bit disk so far, and I'd like to avoid using the netboot installer if at all possible as my internet connection is quite slow.
