After installing the new AMD Catalyst Fglrx Beta driver for Linux (13.8), I could not boot up Ubuntu 12.04 LTS. I have dual boot, but all of my linux files are now missing. The only real thing I can access is Grub, otherwise, normal boot just shows the little AMD icon and a blank screen.

I installed it using terminal, and then it asked me to reboot my laptop. I did, and it showed up with grub loader. After grub, I selected ubuntu, and it just showed "For testing uses only". Then it all dissappears, and I'm left with a black screen that just lights up. The LED for the HDD doesn't even light up. I have no idea what to do.
