I have a Lenovo W520 laptop with i7-2760QM, intel 520 SSD and Nvidia Quadro 1000m.

When i boot the PC with discrete graphics SET in BIOS, the computer totally freezes and the only thing left to do is reboot. This only happens with NVidia drivers for Windows 8 x64 installed (I've tried about 4 different drivers on Nvidia's site).

When i boot the PC with integrated graphics set in BIOS, there is a momentary "hickup" after about 10 seconds (instead of freezing) and then everything is working fine.

When i boot the PC with integrated graphics OFF and no Nvidia drivers installed, the same thing happens as described above with integrated graphics.

I've tried doing


bcdedit /set disabledynamictick yes

2) Disabling VT-x in BIOS (Seriously would prefer not to disable it, since i use VM-s almost every day)

but no dice.

The only thing that worked was to enable the Hyper-v feature. I was then able to boot properly with discrete graphics and Nvidia drivers installed, but since i use VMWare for VM development this was no solution (VMWare complained about not being able to launch because of Hyper-v being installed).

I followed the instructions in this tutorial, to be able to run VMWare. Then the computer just booted into a black screen past Windows logo.

How to boot Windows 8 x64 without freezing with Quadro 1000M enabled, Nvidia Drivers installed and Hyper-v feature preferably disabled ?

Have you updated your BIOS to the latest version and have you tried a fresh Windows 8 install (not upgrade from previous OS)? – kobaltz Oct 31 '12 at 3:26
@kobaltz Yes and yes (tried both actually, upgrade and fresh install). – John Nevermore Oct 31 '12 at 3:28

It looks like the issue that your having is not uncommon and in fact is happening to several people. The past post has a crappy work around, but does show hope and promise for an updated driver with this issue fixed down the road. Unfortunately, and this isn't a great solution, but revert back to Windows 7 until a stable solution is found.

Here is something wacky: try forcing the old Windows 7 drivers. This worked a computer I am working on at the moment.

Out of curiosity was this a clean install?

If you run vmware as often as you say you do, it makes 10x times more sense to just run Windows 8 in the VM and run Windows 7 for now.

He has indicated that it was both an upgrade and fresh install attempted. – kobaltz Oct 31 '12 at 3:40
I see the comment but it is not clear at what point he did the clean install. It was perhaps not clear what I asked :-) – Mikhail Oct 31 '12 at 3:42
@Misha I first upgraded from the previous installation of Windows 7. After being unable to boot i did a fresh install if that's what you're asking. – John Nevermore Oct 31 '12 at 6:58

Type in services.msc

Stop the Hyper-V Virtual Machine Management and set it to Manual

Latest Update....

As per as Nvdia & Lenovo its a bug that is causing the issue when hyper -v is enabled and they are trying to find a workaround for this

Hope it helps..

No dice, unfortunately. Instead of the 10 second wait period, Windows 8 freezes right from the start of the log in screen. – John Nevermore Nov 3 '12 at 7:39
I will try to find another way..... – Sant14 Nov 3 '12 at 7:51
