Windows Boot Manager Boot Configuration Missing

Chelsea Bordonaro 0 Reputation points

Computer was plugged into a surge protector but our whole block lost power last night. This morning when I booted the computer I got an error stating the following:

Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

  1. Insert your Windows installation disc and restart your computer.
  2. Choose your language settings, and then click "Next"
  3. Click "Repair your computer."

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

File: \Boot\BCD

Status: 0xc000000f

Info: The Boot Configuration Data for your PC is missing or contains errors.

How do I figure out who to contact? Is there a way to do it without the disc? I also realized in this process that my boot manager was on my external drive, not sure how it got there.

    First things off, there is always a possibility that the device is damaged and would be unrepairable. But still, you can attempt next actions:

    Check the drive configuration in the BIOS

    Check how to enter the BIOS of your motherboard with the manufacturer information (sometimes is DEL key repeatedly, F2, or DEL keys depending on the manufacturer)

    Inside the BIOS locate the Storage or Drive settings and ensure that the drive is correctly configured as UEFI or EFI, and check Secure Boot is enabled or disabled depending on your working configuration

    Use the Startup Repair.

    During boot, press repeatedly F8 (or hold Shift + repeatedly F8, depending on some BIOS) to enter the Repair mode.

    Then Select Advanced Options and Startup Repair

    Then Windows will attempt to repair the boot system on the system drive

    Manually rebuild BCD

    Following the same steps before to access the repair mode, find and open the option for "Command Prompt"

    Then run in sequence:

    Bootrec.exe \fixmbr

    Bootrec.exe \fixboot

    Bootrec \rebuildBcd

    Bootrec /ScanOs

    The process will fix and rebuild corrupted data on your boot partition.
