\boot\BCD le démarrage de Windows a échoué.

Solved
Hello,
I am the owner of an Advent 4211, and I have a message at startup:

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

1- Insert your CD and restart
2- Choose your language setting and click Next
3- Click Repair your computer

File: /boot/BCD
Status: 0xc0000098

Info: The Windows Boot Configuration Data file does not contain a valid OS entry

So I would like to know how to fix it knowing that I do not have a CD drive. Can I simulate a CD drive with an external hard drive or a USB stick? Thank you for your reply.
Configuration: Windows XP Opera 9.63

  1. I managed to solve this Boot Manager problem with the missing file "Boot\BCD" using the installation CD of Windows [my case regarding the upgrade from Windows Seven and dual boot with XP].

    Actually, I used the installation CD to browse the files on my computer and found a BCD file in my Windows Seven partition, but I couldn't find the folder "C:\Boot\BCD" because it seems well hidden.

    First, I ran CHKDSK /f /r on my hard drives.

    Then, I used the command prompt provided by the installation CD to navigate to the hard drive and the Windows Seven partition where a BCD file was easy to find [D:\Boot\BCD] by typing:

    cd /d D:\boot
    xcopy D:\boot\BCD C:\boot\

    and I restarted. Basically, I replaced my missing BCD file from Windows XP with the one from Windows Seven [it should work with Vista].

    Then I restarted. From there, I accessed the XP recovery console, which allowed me to easily recover my XP session. And thanks to this, still with the Windows 7 installation CD, I repaired, and there we go ^^.

    I hope to help!

    3. I followed the following steps from a tutorial I found online:

      - In the System Recovery Options dialog box, click Command Prompt.
      - Type Bootrec.exe and press ENTER.
      - bcdedit /export C:\BCD_Backup
      - c:
      - cd boot
      - attrib bcd -s -h -r
      - ren c:\boot\bcd bcd.old
      - bootrec /RebuildBcd

      I am indeed facing the error mentioned in this topic, but now I can no longer find my D drive. I can't access it... When I start my system restore with the Windows 7 CD, no operating system is detected, whereas it previously showed Windows 7...
      Did the manipulation I followed delete it? If not, how can I access it to do what shiinji did?

      I'm very worried and anxious.

      Thank you in advance.

    4. Hello. Hmmm, two things seem strange to me, everything in your tutorial is just commands to type?
      Especially "cd boot" because those are not valid commands.
      Personally, to access my folders in C:, I have to type:
      - cd/
      - cd [name of the folder I want to access] ==> cd boot

      Well then. Other questions come to mind as well: what is your operating system? On which hard drive did you install your system(s)? Is it possible that the drive names have changed? Do you think you can access your other drive (D:) through the command prompt?
      To access it, you simply have to type:
      - D:
      And if you want to display what's in it, just type:
      - dir D:

      I await your response.
