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 http://forum.notebookreview.com/lenovo/566338-lenovo-w520-owners-thread-743.html

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

I don't know if this is still up to date but I am about to send my old W520 to my father and I installed Windows 10 on it. I ran into exactly the same freeze issues when trying to install Windows. The installation just froze at the Windows 10 logo. After some research I downloaded and burnt the Lenovo BIOS update DVD and upgraded the BIOS to 1.43 (was 1.34). After that Windows 10 installed without a hassle. However the computer just freezes 9 out of 10 times on restarting at the Windows logo. That was when I was directed to this thread in search of solutions. I disabled both Virtualization options in the BIOS->Security->Virtualization, and enabled the display option of BIOS->Config->Display->OS Detection for NVIDIA Optimus. After that W520 load Windows well without any freezes.
