BlInitializeLibrary failed 0xc00000bb

Some users encountered the BlInitializeLibrary failed 0xc00000bb error when they were trying to boot their Windows 10. If you are one of them, you are at the right place. This article developed by MiniTool Partition Wizard puts together some possible solutions to the issue, and you can try them one by one until you fix it.

Quick Navigation :

A number of users have reported that they see the error message BlInitializeLibrary failed 0xc00000bb when they are trying to boot their devices, especially Surface and Windows laptops. This error prevents users from booting up the computer normally, and the device may still get stuck on the initial screen with the error code even after a restart.

This frustrating error may appear if the motherboard has been recently reset to the default values. Commonly, this is related to the BIOS of the computer’s motherboard. If there are several GPUs on the motherboard and your Windows suddenly stops, the BIOS might be unable to trigger an appropriate power-on self-test (POST), which leads the motherboard to reset to its default values.

The unexpected BlInitializeLibrary failed 0xc00000bb issue is not specific to a certain Windows version, and it may happen to Windows 7/8.1/10 with different PC configurations. There are also multiple factors that might be responsible for this problem, and some of them are listed below:

  • 4G Decoding is disabled.
  • Secure boot is enabled.
  • Some related system files are corrupted.
  • A related registry key is incorrect.

If you are facing the problem unfortunately, don’t panic. Here are some possible solutions from users that may help you get out of the trouble.

After retrieving your data, you can try the following solutions one by one to solve the BlInitializeLibrary Failed 0xc00000bb without worrying about data loss.

Fix 1: Enable 4G Decoding

If you are using 2 or more powerful GPUs on your computer, you are likely to encounter the BlInitializeLibrary Failed 0xc00000bb error when the 4G Decoding (or Above 4G Decoding) is disabled in BIOS or UEFI. On EVGA motherboards, this feature is called EVGA Support instead of 4G Decoding.

To resolve the problem in this case, you can go to enable the 4G Decoding.

Step 1: Enter BIOS setup using the BIOS key which appears on the initial screen. If you can’t see the BIOS key, you can search it online according to your motherboard manufacturer.

Step 2. Locate the 4G Decoding, and set its value to Enabled. The location of the option may vary by the motherboard manufacturers, but it is commonly under the Peripheral tab.

Step 3: Save the configuration and exit the BIOS setup. Then, your computer will restart automatically, and you can check if the error code 0xc00000bb is resolved.

Fix 2: Disable Secure Boot

Secure Boot is a part of Windows 8 and the above versions of Microsoft Windows operating system. It makes your computer boot with only the software that is trusted by the Original Equipment Manufacturer (OEM).

If you are using a cloned SSD or the hardware is modified, this feature may regard these differences as security breaches and prevent your computer from normally starting to protect your device. And this may also trigger the BlInitializeLibrary Failed 0xc00000bb.

So, disabling Secure Boot could help to resolve the problem. You just need to enter the BIOS settings, look for the Secure Boot feature, and set it to Disabled. Depending on the manufacturer of your motherboard, you may find the option under the Boot, System Configuration, Security, or Authentication tab.

Save the settings and exit the BIOS. Then, check if your computer can boot successfully without any problems. If you are still stuck on the initial screen, you can continue with the next solution.

Fix 3: Modify Windows Registry in Safe Mode

It has been proven that the BlInitializeLibrary Failed 0xc00000bb error could come up if the BIOS forgets which SSD/HDD is the primary bootable drive. This is because the computer will clear the Page File that may contain the current boot sequence information at every shutdown.

In this case, you can modify your Windows Registry in Safe Mode to solve the problem. Just follow the steps below:

Step 1: Press and hold the power button for 10 seconds to turn off your computer, and press the power button again to turn on it. Repeat the process 3 times to enter the Windows Recovery Environment (WinRE) and then click See advanced repair options button.

enter WinRE

Step 2: Navigate to Troubleshoot > Advanced options > Startup Settings and click the Restart button. When you get the following interface, press 4 or F4 to select Enable Safe Mode option.

choose Enable Safe Mode

Step 3: After booting into the Safe Mode, press Windows + R to bring up Run window. Then, input regedit and click OK button to open Registry Editor.

Step 4: Now, input the following path in the address bar and press Enter key to locate the Memory Management folder quickly:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

Step 5: In the right pane, double-click the ClearPageFileAtShutdown entry to edit it. Set its Value data to 1 and choose Hexadecimal. Click OK to save changes.

modify ClearpageFileAtShutdown entry

Once it’s done, you can restart your computer to see if the boot sequence can be completed successfully without the BlInitializeLibrary Failed 0xc00000bb error. If not, please move on to the next fix.

Fix 4: Fix MBR and Rebuild BCD

You might also come across the problem if the boot firmware on the computer generates lots of memory fragmentation, which may be caused by issues with the boot configuration data (BCD) and Master Boot Record (MBR). In this case, you can use the bootrec.exe utility to fix MBR and rebuild BCD.

To achieve that, you also need to enter WinRE at first. Then, follow the steps below:

Step 1: In the Advanced options interface, choose Command Prompt, select your account, and enter your password to open the command console.

open Command Prompt

Step 2: Input the following commands one by one and press Enter after each to execute them:

  • exe/fixmbr
  • exe/fixboot
  • exe/scanos
  • exe/rebuildbcd

fix MBR and rebuild BCD

Step 3: After all your configuration data has been repaired, exit Command Prompt and restart your computer and check if the issue has been resolved.

Fix 5: Perform A Repair Install for Your Windows

If your computer still cannot boot properly after you have tried the above methods, perhaps there are some problems with your Windows installation.

In this case, you can perform a repair install (also known as in-place upgrade or reinstallation) for your Windows 10, which will reload your Windows system files, registry keys, and configuration to a known working state without the need to delete your personal data.

After refreshing your Windows components by a repair install, you should be able to boot up your computer properly. If the BlInitializeLibrary Failed 0xc00000bb error appears again, it indicates that this problem has nothing to do with Windows installation, and you might need to focus on your HDD or SSD drive.

As you have already restored and backed up your data with MiniTool Partition Wizard, you can replace your original disk with a new one containing Windows installation and boot your PC from it to check whether the problem is due to hard drive failure.

Fix 6: Contact the Device Manufacturer

If all the above methods fail to fix the BlInitializeLibrary Failed 0xc00000bb error for you, and your computer keeps stuck on the initial screen with the error even if you are using a new hard drive, you should contact the manufacturer of your computer for further assistance. This is always a good solution whenever you come across tricky problems with your device.
