Blue Screen of Death with Error 0xc0000034 on Windows 10

What is Error 0xc0000034 and What Causes It

This error occurs when the system files required to boot the OS (boot configuration data) are missing (damaged or incorrectly configured) on the user’s computer. This problem most often occurs on computers with Windows 10 installed (although there are cases when it appears on Windows Vista, Windows 7 and 8).

The reasons for the error 0xc0000034 may be the following:

  • Random PC failure (usually resulting in a reboot of the computer);
  • Incorrectly installed Windows OS update (in particular, due to the fault of the user himself, who mechanically turned off the PC during the update process);
  • Activity of virus programs;
  • Damage to the system registry due to various reasons.

Fixing Error 0xc0000034 in Windows 10

To get rid of error 0xc0000034, I recommend following these tips:

Method #1: Use the bootrec command functionality

The built-in Windows 10 automatic system recovery tool allows you to easily fix the 0xc0000034 error. To do this, you need to use a bootable disk (flash drive) with Windows 10 (the bootable flash drive we need can be created, for example, using the program “WinSetupFromUSB”).

The sequence of actions is as follows:

  1. Boot from the boot disk (flash drive). To do this, first go to the BIOS, in the sequence of bootable disks, first install the DVD or Flash drive with the OS, reboot your computer, and boot from the disk or flash drive;
  2. In the recovery window that appears, select “System Restore” at the bottom;
  3. Next, click on “Diagnostics” or “Troubleshooting”;
  4. Then click on “Advanced options”, select “Command prompt” (the command prompt can also be called by pressing Shift+F10 in the menu);
  5. In the command line interface, select the English keyboard layout and enter the command:

bootrec /rebuildbcd – and then press enter.

The system will perform the boot file recovery procedure and prompt you to add the operating system found on the disk to the boot list. Press “Y” (yes). If you have multiple operating systems installed on your PC, then press “A” (all). Reboot the system.

Use bootrec /rebuildbcd command to restore the system

If this method does not help, reboot your computer, go back to the command line functionality using the example above, and enter the following in sequence, remembering to press enter after each command:

Bootrec /fixMBR

Bootrec /fixBoot

Bootrec /scanos

Bootrec /rebuildBCD

Restart your PC again.

Method #2: Use Easy Recovery Essentials

The second method for fixing error 0xc0000034 involves using a special system recovery tool called “Easy Recovery Essentials” (this method is effective not only for Windows 10, but also for earlier versions of Windows OS).

Using this program is especially important if you do not have a boot disk or flash drive with your PC’s operating system at hand. Do the following:

  1. Download the Easy Recovery Essentials image;
  2. Create a bootable disk (flash drive) with this program;
  3. Boot from the disk (flash drive) with “Easy Recovery Essentials”;
  4. Once this program starts, select “Automated Repair” there and click “Continue”;

    Use the functionality of the Easy Recovery Essentials program to restore the system boot

  5. Select the disk with the problematic Windows OS installed on it from the list of disks, and click the “Automated Repair” button at the bottom;
  6. The program will restore the system, find and fix all errors found. After the process is complete, click “Restart” to reboot the system in normal mode.

Method #3. Check and Recover Bad Sectors

The third way to fix the error in Windows 10 is to use special programs (level “Partition Guru”) that allow you to restore bad sectors on the hard drive. To do this, you will need to install “Partition Guru” on your computer, connect the hard drive to this PC, on which the system with the BSoD and error 34 is located.

Then run this program, in its working window in the list of disks select the problematic disk, right-click and click on “Verify or Repair Bad Sectors” — “Start Verify”, and then “Repair”.

Use the capabilities of the program “Partition Guru”

How to fix 0xc0000034 in Windows 7

Let’s also consider how to fix error 0xc0000034 in Windows 7.

Method #1: Use the bootrec command

In addition to the already mentioned Easy Recovery Essentials tool, I also recommend that Windows 7 users try to use the standard system recovery functionality. To do this, boot from the boot disk and select Repair your computer at the bottom (system recovery). In the system recovery window that appears, select the command line and enter:

bootrec /rebuildbcd — and press enter. Restart your PC.

Method #2: Use the built-in system recovery option in the OS (if available)

Restart your computer, press the F8 key periodically to open the recovery menu (which also has the well-known “Safe mode” option). In the recovery menu that appears, select “Repair your computer” at the top and press enter.

Follow the same steps as in Method 1, but instead of the command line, select the “Startup repair” option.
