hi guys i had this problem in this morning (https://imgur.com/gallery/67pRsbV)

it seems that I have to rebuild the bcd i tried to do these :

BOOTREC /SCANOS
BOOTREC /FIXMBR
BOOTREC /FIXBOOT
BOOTREC /REBUILDBCD

but I had access denied in /fixboot

anyway I could boot to the pc with the USB idk how, so is there any way to rebuild the bcd as long as i could boot the pc ? because i couldn't solve the access denied so maybe i can rebuild the bcd while i can boot the pc

    Hello how are you?

    Welcome to the Microsoft Community!

    My name is Luciano L., I am here to help you in the best possible way.

    For this scenario you will have to start Windows from the DVD, before starting the procedures I suggest that you disconnect any USB device from your computer, preferably leave only the keyboard and mouse connected to the computer and follow the steps below;

    To do this, please carry out the following procedures.

    1. Press F8 during your computer's startup (before starting Windows). In the Windows startup options, select the first option, which is "Repair your computer"
    2. Select the operating system you want to repair, click next.
    3. In the system recovery options, click Startup Repair.
    4. Restart Windows when prompted or at the end of the repair process.

    If the problem still persists, I suggest that you try to rebuild the BCD store using the Bootrec.exe tool

    To do this, please follow the steps below.

    1. Press F8 during your computer's startup (before starting Windows). In the Windows startup options, select the first option, which is "Repair your computer"
    2. Select the operating system you want to repair, click next.
    3. In the system recovery options, click "Command Prompt".
    4. Type at the prompt, Bootrec / RebuildBcd, and then press enter. If the Bootrec.exe tool runs successfully, it will present you with a Windows installation path.

    To add this entry to the BCD store, type Yes (or Yes) and press Enter. A confirmation message will indicate that the entry has been successfully added to the BCD Store.

    If the Bootrec.exe tool cannot find a missing installation of your Windows, you will need to remove the BCD store, and then you will need to recreate it.

    To do this, enter the commands below in the order they are presented. Press enter at the end of each command.

    Bcdedit /export C:\BCD_Backup

    ren c:\boot\bcd bcd.old

    Bootrec /FixMbr

    Bootrec /fixboot

    Bootrec /rebuildbcd

    Restart Windows and verify that the behavior is still displayed.
