The error code 0xc000000f indicates that the Boot Configuration Data (BCD) file is missing or corrupted. The BCD file is a vital part of the Windows boot process, as it contains information about how to load the operating system and its components. Without a valid BCD file, Windows cannot start properly.

The BCD file is located in a hidden partition on your hard drive, and it is usually created and updated automatically by Windows. However, there are several possible reasons why the BCD file might be missing or corrupted:

  • Power outage or a sudden shutdown that interrupted the boot process and caused the BCD file to be incomplete or corrupted
  • Malware infection that damaged the BCD file or the boot sector, which is the first sector of the hard drive that contains the code to load the BCD file
  • Disk error or a bad sector that corrupted the BCD file or the boot sector, making them unreadable or inaccessible
  • Hardware failure or a faulty cable that prevented the PC from accessing the BCD file or the boot sector, such as a damaged hard drive, a loose SATA cable, or a faulty motherboard
  • Misconfigured BIOS or UEFI settings that changed the boot order or the boot mode, such as switching from Legacy to UEFI or vice versa, or disabling Secure Boot
  • Wrong partition or drive letter that confused the PC about where to find the BCD file, such as changing the active partition, resizing or deleting partitions, or cloning or swapping hard drives
