BOOTBCD 0xc000000d - Unreadable Boot Configuration Data
May 2, 2010
I am running Windows 7 64 bit Ultimate on two PCs on my home network. I went to use one yesterday and was presented with a black screen. I rebooted the PC hoping that would solve my issue and was presented with the following error message while trying to reboot:
Windows failed to start. A recent hardware or software change might be the cause.
File: BOOTBCD
Status: 0xc000000d
Info: An error occurred while attempting to read the boot configuration data
I checked my other PC and saw that it had been updated with several Windows patches yesterday. I'm guessing that the broken PC had an issue installing or rebooting from one of the patches. I ran the repair utility on the windows 7 dvd as instructed by the error message. It was unable to find a previous installation of windows with an error box saying: The file or directory C:BootBCD is corrupt and unreadable please run Chkdsk utility.
I tried the auto repair anyway, which appears to be working until the end when it gives me the "The file or directory C:BootBCD is corrupt and unreadable please run Chkdsk utility" error again. Then it says it can't save the fixes and says it can't be repaired. When I check the details it says I need to "repair offline" and that it cannot find an OS installed.
In my searches for an answer, I read about rebuilding the BCD through the command prompt. I ran the following commands:
BOOTREC /FIXMBR - said it was successful
BOOTREC /FIXBOOT - said it was successful
BOOTREC /REBUILDBCD - failed saying The file or directory C:BootBCD is corrupt and unreadable please run Chkdsk utility
I ran chkdsk and got no errors. I only have one hard drive, but when I go to a command prompt (from the repair section on the Windows 7 Install disk) it defaults to D:. I checked C: and it appears to be making the reserved system space drive C:, which would explain why I can't find a windows install on it. Worst case, If I just go down the path of re-installing windows without formatting the drive, will it pickup my old settings?
Here is what system info I could get (from the BIOS startup diagnostics):
Main Processor: AMD Athalon 64x2 Dual Core Processor 3800+
Memory Testing: 2030592K +64M shared memory
Memory Information: DDR2 533 Dual Channel, 128 bit
CPU L2 cache size: 512K x 2

I was trying to get my laptop to boot into safe mode to get rid of a file. I went to msconfig and picked Safe Boot, after I restarted my laptop, I got the message:Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."
If you do not have the disc, contact your system administrator or computer manufacturer for assistance.File: BootBCD Status: 0xc0000034 Info: The Windows Boot Configuration Data file is missing required information.When I hit enter, it just restarts my laptop and brings me to the same screen. My laptop did not come with a installation disc.. The only thing I did was change a setting which I thought was going to boot me into safemode in msconfig.

I'm getting this every time I boot up my computer. It happened after I had my computer on "sleep". When I woke up and tried to open my laptop, it shut off and showed me this:

It simply takes me to the same screen when I hold "F8". So I cannot get the "Repair your computer." Option. I do not have the windows installation disc. Also, all I can do is basically start up my computer and it takes me to that screen every time.

One of my friends has a Windows 7 computer, but suddenly it could not start,I got an error like this
File: BootBCD
Status: 0xc0000098
Info: The Windows Boot Configuration Data file does not contain a valid OS entry
And I ran a Code: chkdsk c: /f /r followed by a Code: Bootrec /RebuildBcd , where it asked me, if I want to add the entry to the BCD store, and of course I answered yes Afterwards I rebooted the computer, but it came up with a blank screen. I then tried to restart the computer and it keeps coming up with a blank screen. I tried to repair using the Windows 7 - cd's repair, but with no succes. It found the Windows 7 Home Professionel, but when I tried to repair it, it says, that it could not find the OS (something like noOSInstalled). I then came into cmd again, and tried first with Code: BootRec , but it could not find the OS.Now I set it to run Code: chkdsk over the night, but what can I do, if I comes up with the blank screen again? Do I have to reinstall the computer, or are there other solutions?
CHKDSK found ad sectors in the following files Code: WindowsassemblyNATIVE~1.303PRESEN~1FFB7C7~1PRESEN~1.DLL
WindowsassemblyNATIVE~2.303SYSTEM~3.SER559EBA~1SYSTEM~1.DLL If this indicates something
Maybe I have to try with F8, when I restarts the computer for the first time after running the Code: BootRec .

im getting that message upon startup. Im running windows 7.It requests for the windows recovery CD to be inserted, so when I put the CD in to boot I get a "windows is loading files" then a starting windows with the windows logo then just a black screen with a cursor, I left it like this several times for at least an hour an nothing happened.I can't press F8 to access safe mode etc, nothing will happen.Pressing F12 to boot from CD just does the same thing as putting the CD in normally.

I'm getting this error after a forced shut down. I'm told to insert installation disk and repair but I don't get this option, I'm just returned to the same error message. I have tried restarting and loading windows from the installation disc. I'm told that windows is loading and the windows logo appears but after a while it goes to a black screen with only the mouse cursor showing.

I'm trying to get a Toshiba satellite L300D to start Win-7. It gives an error message:
"An error occurred while attempting to read the boot configuration data"
Not really sure what that means, but my guess is thats a file that it isn't finding. My pic isn't very clear, the Status is 0xc000000f, again not sure what that means. This machine has been running and well behaved for a long time.

I was having problems booting Windows 7, so I attempted to use the Bootrec.exe tool to rebuild the my BCD. But I screwed that up big time.Now I get the following error message on a black screen when I attempt to boot up: Windows Failed to start. A recent hardware change or software change might be the cause. To fix the problem:
1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, then click "Next."
3. Click "Repair your computer."
If you do not have this disc, contact your system administrator or computer manufacturer for assistance.The Windows Boot Configuration Data file does not contain a valid OS entry.As far as I can tell, the hard drive is operational. The BIOS detected it and it passed the diagnostics test.

I was messing around with the partition editor in Fedora 14 and accidentally changed the file type on the boot partition. When I go through the startup repair and do the command prompt method, when I enter bcdedit I get the message "The boot configuration data store could not be opened. The system cannot find the file specified"When I do bootrec.exe /fixboot it give me this. "The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded an that the volume is not corrupted" /fixmbr says that it completes successfully btw.

It's my daughter's computer. A little e-Machine, 250G HD, Windows 7 32-bit on it. Out of nowhere her computer wouldn't boot up. I can get it to try to boot using the Windows disk, it gets so far, and then the repair fails saying:
The file or directory C:/Boot is corrupt and unreadable. Please run chkdsk utility.
I try to re-install. she had backed up everything on my external just days before. It gets near the end, and then the same error comes up. I cannot get into anything else. Nothing else will load. I don't even know how I can run chkdsk. Unfortunately the computer is about three years old and she can't remember the specifics except there is only one HD in it. She had no internet at her place so it's not because she suddenly installed something. She was using it to watch movies and listen to music mostly. I'm at wits' end, can't figure it out.

I'm having trouble with my very new computer (Lenovo Y480 with Windows 7 Home Premium 64 bit), which I've narrowed down to the following sequence:
1. I restored computer to original factory settings (to rule out possible causes)
2. I ran msconfig, and checked the boxes 'Safe Mode' and 'Networking.' I got the following error message:"System configuration cannot save the original boot configuration for later restoration. Boot changes will be reverted. The system cannot find the file specified"
3. The default boot option disappeared from the boot menu (Windows 7, default OS, current OS).
4. When I restarted my computer, it would not boot and gave me the error 0xc00034, stating that the file BootBCD was missing.
I did not do anything else with my computer after restoring the factory settings, and I did not connect to the internet. I originally encountered the problem when I wanted to try installing Windows updates in safe mode after some of the installations failed. I have replicated the error several times, including after successfully installing all Windows updates.

I am running Windows 7 x64 Ultimate on my desktop (home) and Windows 7 x64 Pro on my laptops. I bring my personal laptop to work which I use for emails and browsing. There is sensitive information that I would not like to share for obvious reasons. I am running into a problem making sure the information is not in "shared" mode while at work.
Work has their own network, which I am unable to connect to because the Sys Admin is lazy and will won't provide me a VPN connection directly to the system. So what I have done is use the public WiFi that we make available to our customers and connect through my own VPN off the public WiFi system. I want to make sure that I am not inadvertently sharing documents or other information doing so. When I connect to the network at work I use the "Public" setting.
What makes it more difficult is I have a similar situation at home, in which we have one internet connection through a router coming in and several people use the system. The location of the router is actually upstairs where I do not have access to, I use a Netgear WNR2000 v2 (I rent out rooms in my house), so I am forced to connect to the router wireless.
I personally am not a gamer, but one of the tenants is. I almost always use my VPN service at home to connect, but I am unsure if this is the correct set-up. I don't want to share my printers, video, etc. with everyone in the house. I am using Norton 360 for protection with Firewalls and Anti-virus software. I connect through Golden Frog VPN service for security.
I am going to connect my desktop Gigabit switch with my devices but again want my system secure, but not limited because of my situation. It is safe using the router for access and then creating this "sub-network" for my devices (for the router I am the admin)? Is there a better method or suggestion that one might have. I would really appreciate the input for this complicated matter. Should I change my workgroup for home and work? Currently its the default WORKGROUP domain for both.

So I've been using my 64GB ssd as my windows 7 boot drive and i have a 1TB hdd as my data drive. Recently the my computer has begun to freeze up with errors like "explorer.exe" has stopped responding or "windows" has stopped responding and half of the time when i try to boot it says it cant find windows. This has lead me to believe that my ssd is dying despite being only a year old. I need to RMA my ssd but to do that i would be losing my boot drive for weeks. So I thought id try to create a system image so that i can simply put my boot drive on my hdd, but when i try to create the image it says that the image would be 711GB because its including all of my hdd (which contains all my user libraries and downloads). My question is: how do I make windows stop thinking that my hdd is a system drive so that I can create a reasonably sized image, or more generally: how can i easily move my boot drive to my hdd? Also, I've read some posts about using "easyBCD" to accomplish the latter but I'm not sure that's exactly what i need in this situation.

I am helping a friend out with her computer, she had one of those annoying viruses that say you have a bunch of things wrong and try to get you to buy stuff and a few others that I can't remember. I ran malaware bytes and got rid of them all. I thought that would be the end of it. She wanted Itunes and it would never install and the error message for it was related to windows updates. She purchased the computer last may and I was looking at the updates and all of the updates have failed since then, first being service pack 1. It wouldn't automatically do it, so I downloaded the standalone file and it would tell me it was unsuccessful and to restart the computer and try again. I downloaded the readiness tool, ran it, didn't work, ran it in aggressive mode, that didn't work. So I gave up and was going to reset it back to factory. The F8 command for the advanced boot methods does have "repair your computer" option but I click it and it just starts windows normally. Over and over. I made a repair disc through the windows options, and dell data safe, and when I boot from them I get the winload.exe file is missing or corrupt status: 0xc000000d and when I use dell data safe program to restore back to factory, it restarts and gives me the same thing. I have googled all day and searched forums for hours and I am getting nowhere. Resetting it to factory was going to be the easy way for me, and now I just want to throw the thing out the window.

I recently added a hard drive to my computer (SSD), and installed Windows 7 x64 onto it. The result being a dual boot system, which by default boots to the SSD, and optionally (by Windows Boot Menu), can be booted to the original drive (standard mechanical drive).
Initial setup went fine, however I decided to customize the Windows Boot Menu, so that logical names could be associated with each operating system instance. To do this I used EasyBCD and I altered the names in the Windows Boot Menu from: Quote:
Windows 7
Windows 7
to... Quote:
Windows 7 - SSD
Windows 7 - Standard Drive
Shortly after the modification I noticed that I was no longer able to boot into the original OS. Instead I was being presented with a "Repair Windows" option. Figuring that my EasyBCD "tampering" may have had something to do with the issue I decided to change the names back to "Windows 7" in the Windows Boot Menu. However doing so had no positive impact on boot up of the original OS.
After booting again into the original OS I accepted the "Repair Windows" option, and then left the computer over night to do it's "thing". After completion of the "Repair" the situation has deteriorated -
* Windows doesn't load (the same as before)
* Windows doesn't present a "Repair Windows" option (it did before)
* The computer reboots a short period after the "Starting Windows" screen is presented
As a side note the drive is in good health, and all data on it can be read from within Windows 7 when I boot to the SSD OS.

I'm trying to restore my Windows 7 64bit machine to its factory settings at the moment, and I've tried the following but they've all failed.1.) Boot up and hit F8, select Repair computer, but then it just boots Windows normally.2.) Create System Repair Disc, and from BIOS boot-up, choose boot from DVD-RW, but when it does that and loads Windows files, Error 0xc000000d and winload.exe missing comes up.3.) When I tried to insert the installation disc that came with my computer, it's not recognized and nothing happens (during boot from DVD-RW).*Note - Just today when I tried to do a system restore, it said that I had no previous restore points, but I just restored a week ago, so that might add some info.

I was running Windows 7 on a Dell Vostro 3700 Laptop..After doing a spyware scan and finding and deleting all the entries I found, the next time I turned it on I get the error: oxc000000f "An error occured while attmepting to read the boot configuration data File: BootBCD"
I have looked online for solutions and tried using the Windows 7 disc (a copy) and also tried using 3 recovery disks, these all fail because it just stays completely black with a cursor (left for hours even) or I get a error message something around the lines of "insert correct boot media into the correct boot device" and I have no idea what this means. I cannot do a repair because I can only get the Windows disc to load if I remove the hard drive?? this is the only way I have got it past the green loading bar, so I am stuck and have no idea what to do..it only seems to respond to cds if the hard drive is removed?.. this all happened very suddenly and now I have a very expensive �800 paperweight
To add to this - I also tried the command prompt typing the bootrec.exe code that I found on the internet..selecting command prompt from the option when the Windows 7 disc was loaded, but basically it came up with an error of some sort and it had a drive letter of X:/ on the command prompt ?? ..Also to get to this the hard drive was removed because like I said I cannot get the discs working with it in.. I'm guessing this means the hard drive is screwed but there is clearly a problem with the boot sector and I have no idea on repairing it now.

Setup a test PC at work the other for Windows 7 32 Bit and Windows 7 64 Bit (dual boot). Set the dual boot up with EasyBCD. It was working fine until about 20 minutes ago.
I have tried the automatic startup repair but it does not fix the problem. I have also gone through Bootsect.exe and Bootrec.exe commands and they have succesfully written new MBR's and Bootsectors yet the PC still restarts. I have had to /force the previous commands to run.
I have also tried Chkdsk /r but for some reason it just runs through very quickly and finds no errors.
Any ideas as the PC's also have the virtual XP setup.

I downloaded the RC from the microsoft site. While attempting to install every is good and going well and I am doing an custom install which is supposed to be a clean install. I get really far in after expanding files and a couple reboots and while completing the installation near the end i receive the error:
Windows could not change the boot configuration. Windows installation cannot continue.
I have looked around for the answer and it requires you to go into registry and change some things. However I can no longer get back into the orginal OS because I choose to do a clean install rather than an upgrade. Cause I felt this would be the best option for me. I just bought a new hard drive hopeing it will fix the problem but I would rather not use it.
is there any way to fix this problem without a new harddrive? And is there a way to wipe the hard drive for a true clean install without being able to get into the OS? Thanks for any help

I have been having trouble with my computer being slow. After doing a repair install it is better, but it did not correct the "freezing up" part of it. Sometimes I can correct it by just clicking all over the screen and other times to ctrl, alt, del and click on different user, but it is a pain. Any one know why it would be freezing up?
