FILE\BCD ERROR CODE: 0xc0000034

  1. #11

    Data saved


    Whew, due to the powers invested in me by old dos commands (good ol' XCOPY) I copied all my .cr2 files to a portable hard drive.

    Now just need to get the computer booting again.

    Thanks for the help!

    Win8.1Pro - Finally!!!


    Run chdksk /r /f on all the hard drives (you'll have to reboot for it to work on the OS drive), then run hard drive diagnostics on all drives ( Hard Drive Diagnostic Procedure )

    Then start in on these fixes:
    Interesting fixes listed here (read all the way through it): /RebuildBCD error

    This post suggests that your OS partition may not longer be active, try the fixes there also: https://neosmart.net/forums/showthread.php?t=9134

    Some good suggestions here (even though it's 7 it should also work in 8): windows 7 boot loader missing/corrupt - Page 2 - Windows 7 Help Forums

    Another more detailed fix: Windows 7 Suddenly Won’t Boot – Reboot and Select Proper Boot Device or Insert Boot Media in Selected Boot Device and Press Any Key – Repairing the Windows 7 Bootloader Russ' Do It Yourself Home Workshop

    It's your choice to either continue trying to fix this - or to wipe and reinstall. I'll continue to provide suggestions, but I'm way, way out of my depth when trying to fix the BCD. Good luck!

    Prophylaxis?


    So, after a month I am finally up and running.


    Thanks to Xcopy and the good ol' DOS prompt I recovered my data, and did a total system restore from a thumbdrive Dell sent me.


    Now reinstalling software. Thankfully knowledge of past frailties led me to keep a spreadsheet of all my software serial numbers in multiple locations (work, thumbdrives, home PC [well, that one was lost in this incident], cloud, etc). At least I did one thing right.


    Switched my carbonite backup to my new computer.


    But...


    No idea why this happened. It was really out of the blue (pun).



    • Should I be doing something like disabling Windows 8 fast startup in an effort to make future events more fixable?
    • Is there some other prophylactic item I can do to avoid this (other then the previously mentioned "get my online backup up and running?")


    And finally, thanks for those who helped!

    Win8.1Pro - Finally!!!


    Over the last week or so I've seen a number of issues that are likely to be blamed on Fast Startup.
    I suggest that the first troubleshooting step is to disable Fast Startup ( Fast Startup - Turn On or Off in Windows 8 ).
    Then monitor to see if the problem recurs.

    I'm starting to use the Windows 7 File Recovery tool (in the Win8 Control Panel) to backup my User Profile and the entire system to a separate hard drive. We'll see how that works out the next time I need it (it's too late now as my installation was pretty messed up before I started the backup). It backs up periodically on a schedule that you set - and keeps as many versions as it can on the device that you specify.

    Hi badchess, I recently experienced the same problem as you and was hoping you can how you used the /xcopy command? I have the same errror on my surface pro and really would like to retrieve my data before wiping it.

    Thanks in advance

    Xcopy Command Details and Examples
    Hi Wullail, my problems stems from a Surface Pro which has this blue screen. I can boot Ubuntu using a USB by choosing "test Ubuntu before install" option. However, when I attempt to access the Windows partition through Ubuntu it comes back as encrypted and can't be accessed.

    I have quite a few important documents on there which I'd rather not lose, is there any hope of recovering those through the XCOPY commands that badchess did in his previous comments?

    Xcopy is windows not Linux.

    You can normally just copy and paste from booted ubuntu, but if your windows partition is encrypted, you are out of luck.

    I see, would it be worth it to try using a Windows 8 recovery USB on this error?
