Windows 8 starts with a black screen and cursor

if it is a graphics driver issue and your screen still works in bios
use shift + f8 to get to a repair menu

most often this is caused by mismatched versions of graphics card drivers (uninstall the graphics driver or restore a restore point
and update the graphics card drivers directly from the graphics vendor website. be sure to reboot your machine
