    Accidently trashed BCD and resolution


    I started with a dual-boot system:
    * Windows 7 Pro
    * Windows 8.1 Pro
    I upgraded to:
    * Windows 7 Pro
    * Windows 10 Pro

    I used EasyBCD to change the default O/S from Windows 10 to Windows 7.
    After that the boot menu was messed up.
    * Windows 7
    * Windows 7
    Then it was
    * Windows 7
    * Windows 7
    * Windows 10

    I used EasyBCDs repair option and rebuilt the menu to:
    * Windows 7 Pro
    * Windows 10 Pro

    After I rebooted the computer couldn't find a valid BCD to boot from.

    Since I used a Windows 10 Pro 32-bit ISO file to install from I had to use
    another computer to burn a Windows 10 Pro 32-bit DVD. I then did the following:

    Boot with the Windows 10 Pro 32-bit DVD
    Select Troubleshoot
    Select Advanced options
    Select Command Prompt

    I typed the following commands
    > bootrec.exe /rebuildbcd
    > bootrec.exe /fixmbr
    > bootrec.exe /fixboot

    After I rebooted computer everything was back to normal.
    I used EasyBCD to change the default O/S back to Windows 7 Pro but this time there were no problems.

    My question is was there an easier way to fix the problem?

    :)

  2. Windows 10 Update KB3213986 Fails Repeatedly with Error Code 0x800F0922; CBS Log Shows Failure of "Boot File Servicing Installer"

    Problem solved; the boot sector and/or BCD store was corrupted. Resolution required using BootRec to rebuild the BCD store and fix the boot sector, and BCDBoot to rewrite the BCD file in the EFI partition.

    Refer to my preceding post for details.

  3. BUG: Hundreds of messages lost after update to OVI Suite 3.1.1.80

    By accident I just realized that most of those missing messages were moved to the trash! I could restore them from there. This is nice of course but however - I never deleted them or moved them to the trash so why did Ovi Suite do this? I deleted nearly
    600 messages!
