Quick Summary
The error code 0xE0000225 in Windows indicates that the operating system cannot find the boot configuration data (BCD). This often prevents Windows from starting correctly, resulting in a boot error.
Common Causes
- Corrupted or Missing BCD: The Boot Configuration Data (BCD) file, which contains startup configuration parameters, is corrupted or missing. This can happen due to disk write errors, power outages, or malware infections.
- Damaged System Files: Critical system files required for booting, such as the Windows bootloader, have been damaged or deleted. This can result from failed updates, disk errors, or operating system corruption.
- Hardware Issues: Hardware problems, such as a failing hard drive or incorrect BIOS settings, can also trigger this error. A faulty storage device can prevent Windows from accessing the necessary boot files.
- Boot Sector Problems: The boot sector, which is a small section of the hard drive containing code that starts the boot process, may be damaged or overwritten, leading to boot failures.
