Fix the BlInitializeLibrary Failed Error (0xc00000bb)

I'm going to tell you How to fix BlInitializeLibrary Failed (0xc00000bb) error in Windows

When Windows fails to boot, or if it crashes on the first screen, or completely blocks access to the operating system, you get this error "BlinitializeLibrary failed 0xc00000bb". The problem appears when this launch is started, blocking Windows functionality. When the code 0xc00000bb appears, it means that there is something wrong with the system initialization library. This can happen for several reasons, including firmware, boot configuration, or memory issues.

How to fix BlInitializeLibrary Failed (0xc00000bb) error in Windows

The Blib initialization library failed with error code 0xc00000bb. Incorrect BIOS settings, especially with "Secure Boot" enabled, is the most common cause. Problems with the Master Boot Record (MBR), inaccurate Boot Configuration Data (BCD), or fragmented system memory are other possible causes.

In this guide, we will look at different ways to fix this error.

1.Disable the security gate.

Sometimes, a smooth system startup can be prevented by security features such as Secure Boot. The security scanner can mistake legitimate hardware updates or BIOS updates for threats. Disabling it in the BIOS can help the system boot normally when these harsh security controls are enabled.

Start pressing the Setup button on the initial boot screen as soon as your computer starts. The setup button is determined by the motherboard manufacturer, however it must be visible on the initial screen. To access the BIOS setup, press the Setup button. Note: See "setup key + *motherboard manufacturer*" online if you cannot see the Setup key (BIOS setup) on the initial screen.

To find the feature called Secure Boot, in your BIOS setup, you must exit to the Security tab. Once you see it, set it to Disabled. Turn off the security gate. Note: Please note that the BIOS menu and exact location of the Secure Boot feature will differ from each manufacturer. If necessary, check your motherboard manufacturer to find out which option you will find in the system setup, under Boot or Authentication.

As soon as you can disable secure boot, save the BIOS settings and exit. Your computer will reboot.
At the next boot sequence, wake up your system and try to see if you can now complete the process successfully without encountering the "blinitializelibrary failed 0xc00000bb" problem.

2. Perform the donkey sequence.

You can help your system find the boot files and settings by taking out the boot sequence. The boot process will stop if the sequence is broken or misconfigured, which can cause problems for your computer to find the correct boot drive or files. By setting this sequence, you ensure that the system continues in the proper direction to efficiently start and load the operating system. What allows your system to function normally is that this step addresses the cause of common boot problems.

To start from the installation media, insert it and press any button.
Click "Repair your computer" on the Windows Setup screen. Remove and repair your computer Choose "Troubleshoot" from the "Advanced options" menu, and then choose "Command Prompt" from the next menu.
Select Advanced boot options Choose the System Prompt Press Enter after each System Prompt, enter the following commands: startup recovery.exe startup recovery.exe /fixmbr startup recovery.exe /fixboot scanos bootrec.exe buildbcd.exe, bootrec Restart your computer
After running the above commands to reflect whether the normal startup sequence has completed.

3. Follow the on-screen instructions to safely manage memory.

If your system has trouble restoring data from the startup sequence during startup, it may be helpful to adjust your memory management settings. To prevent Windows from clearing the page file, which contains crucial startup information, disable the ClearPageFileAtShutdown feature safely. This change improves the system's ability to boot properly without losing key configuration details by allowing it to retain crucial data from memory.

Hold down the Shift key while entering the recovery environment (restarting your computer).
Choke on Troubleshoot > Advanced options > Startup Settings in the recovery menu and hit Restart. To start safely, press 4 or F4. To start safely, press 4 or F4.
To open the Registry Editor, press Windows + R, type "regedit" and then press: Do not click Yes to allow the changes if the UAC (User Account Control) is prompted.

Step One: Computer Key: HKEY_LOCAL_MACHINE System Control Set for Current Control Session Managers Memory Management
To set the Base to Hexadecimal and the Value data to 1 Double-click ClearPageFileAtShutdown. Click "OK" to save. Set the data for the ClearPageFileAtShutdown Value to 1
Restart your computer. If possible, repeat step 4 through 6 and set ClearPageFileAtShutdown to 0 again. Watch for kills.

4. Do you have decoding higher than 4G?

If you use your PC for mining and have two or more GPU cards, you may experience the "bl initialize library failed 0xc0000bb" issue because 4G or higher decoding is not enabled in your motherboard BIOS or UEFI settings.

After enabling 4G or higher decoding, the issue was resolved, according to several affected users who were also mining cryptocurrency. Obviously, the actual location of this option depends heavily on the motherboard manufacturer, but you'll usually find it within the perimeter.

Enabling 4G Decryption

Caution: This feature is called "EVGA Support" instead of "4G Support" on EVGA motherboards.

Step 5: Perform a Repair Installation

If none of the fixes work, a repair installation can help you reinstall Windows without deleting any file or application. It simply reinstates your PC with no major loss apart from some data, while deeper startup issues are also sorted out and problematic system files get replaced.
