  1. Error 0xc0000034, can't access Boot media


    I have been trying to load the BIOS on my computer, attempting to boot from the USB so I could reinstall Windows 10 to allow an unallocated partition. Now I am stuck at this error message when I start up, no BIOS screens, the ESC, F1, and F2 are useless, I have my boot drive on a USB but no way to access it from here.

    Can someone please help?

    \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

  4. Error 0xc0000034, can't access Boot media

    start up error 0xc0000034

    Hi Liu,



    This error can happen due to a recent hardware or software change. Based on your post, you already tried to resolve the issue by going through your PC’s command prompt yet you’re still getting the issue. Have you tried to boot from a USB device with the
    media creation tool? If not, we suggest that you follow the instructions given by
    JKWGOO and Srimadhwa B on this article.
    On the steps provided on the said thread, you may be asked to repeat the steps such as fixmbr and the other steps you already did. The difference is that this time, you will have a Windows 10 media creation tool to boot up your PC.



    Let us know if this resolves the issue for you.
