    The boot configuration data for your pc is missing/errors


    Hello. Last night I set Acronis Disk Director to merge two partitions on my C drive.
    I had an unnallocated 100mb that used to be partitioned as system reserved, but I deleted that partition as it was not needed. So I made a new partition out of that unallocated space and set it to merge with my primary partition on my c drive. It restarted my computer and 40% through, showed an error and restarted quickly. Now I get the following message when attempting to boot my computer:

    File: \Boot\BCD
    Status: 0xc0000225
    Info: The Boot Configuration Data for your PC is missing or contains errors.

    The second partition, that I attempted to merge, now has 1mb of space on it. Whenever I try to run chkdsk on the primary partition, it says that the disk structure is corrupt and uunreadable.

    Any help would be greatly appreciated. I need my c drive recovered.

    The system reserved has The Boot Configuration Data for your PC.

    Try this:

    I had removed the system reserved partition when I first installed Windows 8 several months ago. It was working fine until I decided to merge the unallocated 100mb that used to be the system reserved partition into my primary partition.

    When I launch startup repair via disc, it says "diagnosing problems", then my computer just restarts, without telling me anything.

    I don't think this will work out well considering I cannot access the files on the C drive, and chkdsk cannot check the C drive. Would it still be able to keep my files?

    It looks like Windows is not detecting your Installation- Try booting from the Install Disk, go into a Command Prompt and try "Bootrec /Fixmbr" then "Bootrec /Scanos" - Also check your BIOS boot order, and make sure the drive with the Windows Bootloader is the first drive. This may or may not be the drive with the system files on it. For instance, I have Windows 7 and 8 installed on my system, and the bootloader for both systems is in the drive with 7 in it. Bootrec will allow you to set it to the drive with the system files on it.

    I unplugged all drives but the drive with Windows on it. Bootrec does not seem to help, as it still reports 0 installations when I run "Bootrec /rebuildbcd".

    Try putting all the drives back in, run it again.

    If it is not finding the system files, could be a drive problem, download Hiren's Boot CD from the link below, boot to it, and go into Dos Programs/hard Drive tools. Find GWscan and run it on your system drive, see if there are any Read Errors on it - If there are, trhe program will offer ti fix, do it, it takes about an hour.

    Yeah, trying to use the cd command in cmd from the win8 disc does not work because "the file structure is corrupted and unreadable". I'm currently having Seatools "fixing" the hard drive, although I don't think it will work, I'll report back once it's done, it's been running for about 2 hours now.

    Okay, Seagate tools did nothing, I'm at a loss of options here. I'm currently running the drive through Testdisk in an attempt to rebuild the drive's boot sector and MFT.
