in Windows 8 Consumer Preview (Works with 64-bit)
Select Settings (right bar)/More PC Settings (at bottom)
Then go General/Advanced Startup/Restart Now/Troubleshoot/Advanced Options/Windows Startup Settings/Restart
As your PC is starting up be pressing F8 to get to the menu where you can choose to
Disable driver signature enforcement or Enable low-resolution video mode or Enable safe mode.
Also do a search within Window Settings, find topic called Change Device Installation Settings, and choose your options.
After doing all of these steps I was able to install driver 295.18, however Windows did not know I had a NVidia card installed anymore and I had no display adaptors showing up in Device Manager. Windows was then using some generic display adaptor that was not visible in Device Manager anywhere.
I was able to get out of the predicament by going back to an earlier System Restore point after which Device Manager showed my video card as an unknown device in the Other section and I was able to do update driver, automatically search, it pulled in the NVidia driver off of Windows Updates again, and then Windows knew I had a GTX 580 and it showed up in Device Manager properly.
