    \Boot\BCD Error Code 0xc0000034


    Hi there, and thanks in advance for your help.

    I am using a Lenovo Ideapad 310-15ISK (model name 80SM) running Windows 10.

    I am receiving an error on boot 'Your PC/Device needs to be repaired

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

    File: \EFI\Microsoft\Boot\BCD
    Error code: 0xc0000034'

    I hadn't made an image backup of Windows 10 on this device before this error but I have used a family members HP PC to create a USB image of windows 10. I am not sure what my next step is after making this backup to restore the file, and I'm not well versed in windows repair.

    Many thanks,
    Amy

    You might want to try booting to a repair/recovery disk for your version of Windows 10. This is nicely covered in the TenForums tutorial entitled "Run Startup Repair in Windows 10". For many, but not all, forms of BCD pathology, this will fix things automatically. You have nothing to lose by trying and it may fix your problems. If not, report back here and we'll put out some heavier artillery!

    Oh man, same happened to me a few days ago. I actually wrote a small blog-post about it. Here it is:Recovery - Your PC needs to be repaired

    2017-04-28
    After restarting my PC this morning, I was greeted by a blue screen, telling me, that my boot configuration was missing or contained an error. I was shocked. I had not encountered this error message before and was not quite sure what to make of it.
    Looks worse than it is

    Was my hard-drive broken? Did I loose all my code? How much work did I loose? How much was on my git? And why oh why did I not set up my NAS server as planned. All these elaborate plans on how to manage my data backups... and I never had the time.
    I instantly picked up my phone and did some research. First off: Most likely, all your data is fine and it won't be too much of a hassle to fix this and get you back on track.
    How to fix it

    Luckily for us, this is very straight forward process. Simply follow the 14 steps below.
    Step 1

    You will need your Windows installation media to take care of this. This might be a DVD or USB-Stick. If you do not have your Windows installation media ready, simply visit Microsoft's website and download it.
    https://www.microsoft.com/en-us/soft...load/windows10
    https://www.microsoft.com/en-us/soft...nload/windows8
    https://www.microsoft.com/en-us/soft...nload/windows7
    Step 2

    Once you have your DVD or USB-Stick ready, connect it to your troubled system and reboot. I had to press F11 while rebooting. Some people may have to press F12 to bring up the boot menu. If in doubt, simply google the right key for your make or model.
    Step 3

    Booting from your Windows installation media should bring up the Windows Setup. You may need to choose your language and keyboard settings before clicking on Next.
    Step 4

    Instead of clicking on Install Now, you should find and click on the Repair your computer button in the left lower corner.
    Step 5

    Choose the option called Troubleshoot.
    Step 6

    Select the option Advanced options.
    Step 7

    Click on Command Prompt.
    Step 8

    Now type Bootrec /fixmbr and press the Enter key.
    Step 9

    Next up you will need to type Bootrec /fixboot and press Enter again.
    Step 10

    Type Bootrec /scanos , press Enter.
    Step 11

    One last time, type Bootrec /rebuildcbd and press Enter.
    Step 12

    Type A and hit Enter.
    Step 13

    Close the command prompt by clicking on the X button.
    Step 14

    Click on Continue and the system should boot up again.
    What did I learn?

    Blue screens scare the sh*t out of me. Luckily, this time, it was a simple fix and I got away easy. What did I learn? Backups are important and setting up my NAS server just jumped to the top of my TODO-list.

    This would be one of the repair maneuvers I would provide as "heavier artillery" for the boot problems the OP described. It's possible that simply using the Startup Repair facility would do the trick. But this is certainly another option, as is the boot repair tool from Macrium (which would have been my next step in the chain of possibilities that lead to the command line BCD and boot repairs described in the preceding post).
