Hi Expert,

I am getting BSOD DRIVER VERIFIER DETECTED VIOLATION, I created a bootable USB but there is no automatic repair, and unable to boot to safe mode.

Rest of the method like system restore and pc refresh failure to run. Used verifier cmd and all driver services on "no" thus unable to delete the Existing Settings. Did custom the settings but from cmd unable to restart.

Lenovo Z500 laptop on Windows, 8.1

Appreciate if any expert can assist on because I need my data inside.

Used verifier cmd

Not a good idea on a Lenovo Machine.  

Do you know what driver you updated last?   Find that driver on the Lenovo Support site and try to install that from the bootable USB key.

Failing that, boot with Ultimate Boot or like USB with an operating system, and copy your data on to a USB key or hard drive. Then reinstall Windows.
Used verifier cmd

What specific command? The verifier application has several switches that change what it does. The command you should be using at this point is
verifier /reset

Open in new window

...although you should be running that from safe mode (running it without Windows itself running won't have any effect). So if you can't get into safe mode using the normal tricks, try doing this:

1. Boot from the install media (CD or DVD or USB or whatever you have).
2. Choose to repair your PC.
3. Go to Troubleshoot >> Advanced Options >> Startup Settings >> Enable Safe Mode (pretty sure that's the correct verbiage for both Windows 8 and Windows 10 - I was reading the screenshots off of

If that gets you into safe mode, then you should be able to open up the command prompt (make sure you run it as an administrator) and then run verifier /reset to turn off the driver verifier and reboot.

If that works, then you should be able to use this Microsoft article to help you find the responsible driver (if you don't know what it is already):

More often than not, the driver problems are either audio or video (anecdotal experience).
can you post the dmp file?
you can access it when booting from a live cd, like knoppix  :            
or hook your drive to a working system
