Like the title says, I'm stuck in an endless loop. I'm starting to lose hope. Getting the "IRL NOT EQUAL TO" error with "ndistpr64.sys" being the culprit. Apparently a known virus.

BDOS happens 5 seconds after Windows boots, no way to do anything. I don't have a boot CD or access to another computer, unless you consider a Mac a real computer :P

Any help would be GREATLY appreciated!!!!

I'm on Windows 7, btw, with no access to safe mode.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.
Insert the USB flash drive into the computer and reach the Recovery Environment Command prompt.
Entry points into WinRE

Your users can access WinRE features through the Boot Options menu, which can be launched from Windows in a few different ways:

  •     From the login screen, click Shutdown, then hold down the Shift key while selecting Restart.
  •     In Windows 10, select Start > Settings > Update & security > Recovery > under Advanced Startup, click Restart  now.
  •     Boot to recovery media.
  •     Use a hardware recovery button (or button combination) configured by the OEM.

After any of these actions is performed, all user sessions are signed off and the Boot Options menu is displayed. If your users select a WinRE feature from this menu, the PC restarts into WinRE and the selected feature is launched.

WinRE starts automatically after detecting the following issues:

  •     Two consecutive failed attempts to start Windows.
  •     Two consecutive unexpected shutdowns that occur within two minutes of boot completion.
  •     A Secure Boot error (except for issues related to Bootmgr.efi).
  •     A BitLocker error on touch-only devices.

Boot options menu

This menu enables your users to perform these actions:

  •     Start recovery, troubleshooting, and diagnostic tools.
  •     Boot from a device (UEFI only).
  •     Access the Firmware menu (UEFI only).
  •     Choose which operating system to boot, if multiple operating systems are installed on the PC.

I can confirm that ndistpr64.sys is a malicious file related to the SmartService trojan. Since you cannot boot into Windows, I suggest you post in the Virus, Trojan, Spyware, and Malware Removal Logs forum where our malware experts will be able to help you. Even if you can't provide an FRST log, just post anyway explaining why you can't.


Good luck.
