Hi, I followed this guide to the letter and I think I've done everything correctly. But when I boot, it loads every thing and then it shows me a blank/gray screen with the cursor on the top-left corner.
I can move it and all but that's it, I think that's the screen where it's supposed to tell that the installer is loading and then ask me for the language.

Here are my specs:
-AsRock P67 Pro3 SE motherboard
-Intel i5 2500k CPU
-Asus HD 6950 GPU
