Windows 7: \BOOT\BCD 0xc000000d unreadable boot configuration data

20 Mar 2011   #11

Windows 7 Ultimate, 64bit
it's back

I spoke too soon. After I got it booted with your instructions, I needed to shut down and move my sata cables around. This is what sata ports are on the Asus P8P67 Deluxe MB:

4 x 3GB (Native Intel)
2 x 6GB (Native Intel)
2 x 6GB (Mavell?)

I have 1 120GB SSD and 1 2TB HD on the Marvell ports. I have 2 x 1TB running RAID 1 on the Intel 6GB ports.

After moving the cables I got a boot error and repeated the steps I had taken last time:

Booted to my repair disk, when it tried to repair and restart it immediately returned
"Failed to save startup options"

I then went to the command prompt and:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd - this successfully found 1 windows install, but when I "Add installation to boot list?" “YES”, I get "The requested system device cannot be found"

I then continued on to your instructions:


lis vol (mine is C)

sel vol c



bcdboot c:\windows /s c:

bootsect /nt60 all /mbr

Restart and get the same thing:

File: \Boot\BCD
Status: 0xc000000f
Info: An error occurred while attempting to read the boot configuration data.

Any help is appreciated!


Update. I started thinking maybe the 2 non Intel sata ports were the problem, maybe defective or just diffrent. So I moved all drives onto to Intel ports and rebooted. This time my repair disk was able to fix the start up, and Windows loaded. Cool, right?
I rebooted and opened the Bios to change the sata mode from AHCI or RAID. As it booted i saw a flash of words about "no physical disk" and back to the same problem. Don't know if it was just coincidence so I immediately went in that changes the sata mode back to AHCI, but no change.

Again loaded the repair disk and was able to repair and restart. Window loads, but not before "Check file system on D:"

Attempted a restart from Windows and went right back toe the Window Boot Manger error:
File: \Boot\BCD
Status: 0xc0000225
Info: An error occurred while attempting to read the boot configuration data

I'm heading in the right direction, at lease I can get it to run from the repair disk, Now I need to get it to run without the repair disk. I will try running through the BOOTREC options now.

Same thing after BOTTREC /fixmbr /fixboot /rebuildbcd


After reading and trying so many thinks I lost track, including pulling out the SSD system drive and checking in in a different PC, it was fine. I even formatted it and loaded a backup image I had made a week before when the computer was working, but still same problems!? I don't get that.

I finally decided to reload Windows, but not expecting it to work. It did.

So if a backed up image is not reliable, what is the point? Fortunately I also run all my data on a diffrent disks (Raid1), so that is not an issue. Just a lot of time reloading software (after a long weekend of trying to fix)

Any idea what might have happened? Needless to say, I don't like the idea of this happening again.

Windows 7 Ultimate 32bit
It worked!

I would delete the bcd store and run the commands again. Yes you should be pointing them at the reserved system partition .

Otherwise, at cmd prompt, type:


lis vol

( Look to see the drive letter for your main windows partition - if it is D then type as below, otherwise replace D with the letter diskpart gives for the main windows partition)

sel vol d



bcdboot d:\windows /s d:

bootsect /nt60 all /mbr

restart the pc - you're good.
This worked perfect!

Thank you very much, just registered to say thanks to you...

That is probably telling you it is not a Primary partition. Only Primaries can be marked active.

You had better download partition wiz free boot disk.

Then you can see what you are doing.

Partition Wizard Bootable CD allows user to manage partition directly with partition manager bootable CD.

Windows 7 Ultimate x64
0xc000000d generic error

Hi all, Went through this thread to attempt solving this issue for my system which has both Win 7 Ultimate x64 and 32bit editions.
Few days back had installed Acronis boot loader to ensure I could add another Linux partition, however after running successfully for 3 days, the 4th day the system crashed.
Tried all the steps and managed to recover only the 32-bit version of Win 7, but for 64-bit I still get the 0xc000000d error.

I have the following: System reserved Partition (about 500MB), Win7 32-bit (about 500GB) and Win7 64-bit (about 500GB).
I also installed the MiniTool PartitionWizard and detected 4 error blocks in the partition of the 64-bit OS.
Any suggestions or help appreciated!

Wins 7


I found this old thread. I am having this problem.

Laptop - Dell
Wins 7
My laptop had battery problem, but it was still working with power chord.

Windows failed to start. A recent hardware or software change might be the cause. It installed a software update and when I restarted it I got a black screen with this error.

Status: 0xc000000d
Info: An error occurred while attempting to read the boot configuration data

The problem I am facing is that nothing is happening even if I press F1 to F9 keys. When I press Esc it again brings back me to the same screen. I am not able to go to cmd prompt. I do not have any DVD or CD. Please help me what are my options. I have a lot of data in my computer.
