My windows 8 (consumer preview) desktop does not boot up

[nachoalaves]

When I downloaded a update to my drivers my desktop stopped booting. It loads perfectly fine but when it gets to the screen in which you swipe up, the screen stays black. This has happened before to me and the system, by itself, launched the automatic recover (after many tries).This time, the same error has ocurred, but the automatic recover does not launch. How can I fix this?
Note: I just noticed I posted this on the wrong forum, sorry.

Windows 8 consumer preview? It was just a preview.

That has expired, you actually have to go back to 7 or buy 8.

If you are really talking about the Windows 8.1 Preview, read THIS.
