The most common cause is an incorrect BIOS configuration, especially when “Secure Boot” is turned on. Other possible causes include problems with the Master Boot Record (MBR), bad boot configuration data (BCD), or fragmented system memory. In this guide, we’ll look at different ways to solve this error.
1. Disable Secure Boot
Sometimes, security features like Secure Boot can prevent your system from starting smoothly. Secure Boot may mistakenly identify legitimate hardware upgrades or BIOS updates as threats. Disabling it in the BIOS can help the system boot normally by bypassing these strict security checks.
2. Fix the boot sequence
Correcting the boot sequence helps your system locate the necessary files and configuration needed for startup. If the sequence is broken or misconfigured, your computer may struggle to find the correct drive or boot files, halting the startup process. By re-establishing this sequence, you ensure that the system follows the correct path to initiate and load the operating system efficiently. This step addresses the root of common boot issues, allowing your system to operate normally.
3. Tweak Memory Management keys in Safe Mode
When your system has trouble retaining boot sequence data during shutdown, adjusting memory management settings can help. Disabling the ClearPageFileAtShutdown function in Safe Mode stops Windows from erasing the Page File, which holds important boot information. This change helps the system keep crucial memory data, improving its ability to boot properly without losing key configuration details.
4. Enable Above 4G Decoding
If you’re using your PC rig for mining purposes and using two or more GPU cards, chances are you’re encountering the ‘bl initialize library failed 0xc0000bb‘ error because 4G decoding is not enabled on your motherboard BIOS or UEFI settings. Several affected users who were also mining cryptocurrencies have reported that the issue was resolved after they enabled 4G decoding or Above 4G Decoding. Of course, the exact location of this option highly depends on your motherboard manufacturer, but typically you can find it inside the Peripherals tab. NOTE: On EVGA motherboards, this feature is called EVGA Support instead of 4G support.
5. Perform a Repair Install
If none of the solutions work, a repair install can help by reinstalling Windows without deleting your files or applications. This process replaces corrupted system files, addressing deeper boot issues and restoring your PC without major data loss. If you want to conduct a repair install, you can follow this step-by-step guide (here).
