Hello everyone!
I tried installing 13.04 yesterday and I've run into a huge problem:

Right after install, I enabled fglrx restricted driver from the 'Restricted Drivers' tab in 'Software and Updates'.
It asked me to reboot for the new driver to be loaded, and i did so. Problem is my system did not boot again.
I said ok, i'll try the fglrx-updates driver, so i reinstalled ubuntu 13.04 and tried with that one. Needless to say, i had the same result.

My installation seems to be using Linux kernel Also, here's my hardware, in case it helps:

intel core i5 2500k
8gb ram
amd radeon hd 7870xt
ocz 120gb ssd drive (install disk)

I would appreciate any suggestion on how to fix this.

Thank you!
