0xC000000F 🪟 Windows

Your PC needs to be repaired: The Boot Configuration Data file is missing some required information (0xc000000f)

Windows Boot Manager can’t find a valid BCD entry or boot files — after disk changes, failed updates, cloning or dual-boot changes.

Seen on: Windows

Meaning

The BCD store tells the boot manager where Windows is. Changing partitions, cloning to a new disk, removing a Linux/second OS, or BIOS boot-order changes break it.

Common causes

  • BCD corrupted or pointing to a moved partition
  • EFI partition damaged or missing
  • Disk cloned/migrated
  • Wrong boot device order

⚡ Quick fix

  1. Use Startup Repair from recovery media
  2. Rebuild boot files with bcdboot
  3. Check BIOS boot order/UEFI vs legacy mode

Detailed fix by platform

Windows

  1. powershell
    # Recovery Command Prompt (UEFI): assign the EFI partition a letter, then
diskpart
  list vol
  select vol 4
  assign letter=S
  exit
bcdboot C:\Windows /s S: /f UEFI

How to diagnose

  1. Partitions — EFI partition present?
  2. Mode — UEFI vs Legacy
  3. Changes — Cloning/dual boot recently?
