BCD File Missing in Windows Server 2012: How to Fix That?
When you encounter boot issues, it may be caused by BCD file missing from Windows Server 2012. Read this guide to effectively fix Server 2012 boot issues by rebuilding BCD files.
About Windows Server 2012 boot BCD error
The boot BCD error is a common issue that also occurs in Windows Server 2012 (R2) and can affect various systems, including Dell, HP, Lenovo, and Gateway laptops. The Boot Configuration Data (BCD) is a firmware-independent database essential for boot-time configuration and is used by the Windows Boot Manager.
Depending on the boot mode, the BCD file is located differently: for traditional BIOS, it resides at /boot/BCD on the active partition, while for UEFI boot, it can be found at /EFI/Microsoft/Boot/BCD on the EFI System Partition.
Users may encounter BCD errors after extending the system partition or due to inappropriate operations that damage the Boot\BCD file. Additionally, these errors can arise after installing certain applications, as malicious third-party software can corrupt the BCD store. Problems may also occur when booting from a USB drive with a corrupted MBR or BCD, or due to installation errors in the server. Common BCD error messages in Windows Server 2012 include “Recovery: Your PC needs to be repaired” and “The Windows Boot Configuration Data file does not contain a valid OS entry.”
To fix boot BCD errors in Windows Server 2012, you need to identify the causes, such as non-system disk errors or corrupted files. Or look for error codes like 0xc000000f or 0xc0000098, as these indicate specific problems with the BCD file or system setup.
