I am running the Windows 8 64 bit consumer preview on a virtual drive on a Lenovo Thinkpad W510 that natively runs Windows 7 Ultimate.
This has been working for about a month. It has been fine, though I would occasionally get a BSOD displaying INTERNAL_VIDEO_SCHEDULER_ERROR. Recently, it what I believed would be the solution to this problem, I updated my video card driver (Nvidia Quadro FX 880m).
Next time I tried to boot up, I made it to the Windows 8 dual boot os choice screen as normal. However, when I choose an OS (8,7, or the advanced options choice), I am met at first with a blank screen, and then, the screen begins to flash about every second where the backround switches between different shades of grey, and the normal Windows blue. It keeps flashing, and I can see my normal mouse pointer (not flashing), until I restart or sometimes (only on Win 8), I get a blue screen. This time the error states SYSTEM_SERVICE_EXCEPTION win32k.sys. And crash. I've managed to get into the system at the command prompt with safe mode, but I'm not sure what the best course of action is here. I need nothing on Windows 8 and would be happy to remove it, but I want to make sure I do it properly. Any ideas on what the best course of action is?

At boot press F8 and select Enable VGA Mode instead of command prompt, then uninstall nvidia drivers and get new one from lenovo thinkvantage system update or from nvidia site, pick whql variant for your card. – week Dec 2 '12 at 4:14
This is what I would've done - but I was wrong about being safe mode - I was actually in the recovery console, thus I could not do this. However, I did solve it, and I will update with the solution. Thanks for your help – user1167442 Dec 11 '12 at 4:15
