This article is specific to Windows 7 but similar errors occur on all versions of windows.
NOTE: You will need your Windows 7 DVD or a USB with the recovery console installed.
IF USING A USB STICK MAKE SURE IT IS PLUGGED INTO A USB 2 SLOT, USB 3 IS NOT SUPPORTED; It will error with ‘failure when attempting to copy boot file’.
After rebooting your computer you receive the following error:
Windows Boot Manager
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1.insert windos cd and run a repair your computer option.
File: /boot/bcd
Status: 0xc000000f
Info: an error occurred while attempting to read the boot configuration data.
You may receive a similar error which lists the error code as 0xc0000034 or missing file: windows\system32\winload.exe instead.
You may also receive further errors after trying to repair the bcd store using bootrec and bcdedit as follows.
The requested system device cannot be found.
The “Windows Boot Configuration Data File is Missing Required Information
The “Windows Boot Configuration Data File is Missing
An error occurred while attempting to read the boot configuration data
Cause and Fix
The most likely cause of this error is that you tried to dual boot two operating systems and then later decided to remove one. This inadvertently may have deleted the bcd boot store. The trick here is to run the above commands in the right order and set your boot partition to active. Let’s get started.
Make sure your boot partition is set to Active
Boot from your DVD and choose the repair option. From the recovery console type “diskpart” and press enter and then type “list disk” to get a list of physical disks installed.
In the example here I only have one disk in my machine, if you have more than one identify the disk which has the Windows boot partition on it and then select it. Select it by typing “select disk 0” (in my case). Now type “list partition”. The Windows 7 boot partition is a 200 MB primary partition. As you can see here it was on disk 0. Select it by typing “select partition 2” or whichever number matches your 200MB partition.
Now type “detail partition” and look where it says “Active”. If it says yes then move onto the next section otherwise type “Active” and press enter, Windows should report the partition is now marked as active. Now reboot and boot into the recovery console again.
Repair the MBR and boot sectors
From the recovery console run these commands in this order:
- bootrec /fixmbr
- bootrec /fixboot
Now reboot the machine again into the recovery console and type “bcdboot path to your windows folder“. Your windows folder will normally be c:\windows but in the recovery console it may show up as D:\windows so make sure you get the path right. In my case it was “bcdboot d:\windows”. This will will build a new bcd boot store and copy over all boot files needed to boot. Now reboot your machine one last time and it should work. If it doesn’t run the two bootrec commands again.
If you have any additional operating systems you want to add use the bootrec /scanos command.
If you still have issues you may have a system with a GPT disk. In this case you will have an EFI sytem partition that must always be active. See the following if you get Failure when attempting to copy boot files or suspect you have an EFI system.
Thanks for this info. I followed instrucctions but at the last step when I execute bcdboot d:windows I get FAILURE WHEN ATTEMPTING TO COPY BOOT FILES.
Also tried bcdboot c:windows … same thing. 🙁
Did you check to make sure the windows folder is in that location by using dir commands etc? Just keep changing drive letters and looking for the windows folder until you find the location.
If you ran the command correctly and pointed it to the correct windows folder then it sounds like your installation is corrupted.
I also don’t know anything about your environment. If you have a dual boot system then you could be pointing it to your XP windows folder for example which won’t work. You need to point it to the Windows 7 windows folder. Let me know your results and answer the questions above so I can help you more. 🙂
hello DARYL, when i try to type bcdboot c:windows, it says ‘failure when attempting to copy boot files’…. what shall i do now? thanks in advance.
i got the same error and what i do is just restart and go to the console again, retype the bootrec commands again and finally the bcdboot succedded 😀
when you copy from a Windows 8 is:
bcdboot X:\windows /s X: /f ALL
when you copy from a Windows 7 is:
bcdboot X:\windows /s X:
Replace X with drive letter for windows drive
try;
c:
dir
This will show the contents of the drive to look for the windows folder.
Thanks for the reply. Saved the day
Thanks so much. You saved my computer. 🙂
Hard Disk Problem…
Perhaps you are trying to set x:\boot\bcd on a partition that is logical or extended and not primary. I know it won’t work on a logical and AFAIK not on an extended.
If you have partitions of the various types, try one of the primary ones.
Thanks for your prompt answer.
PC has Windows 7 64 bits. I can’t boot at all, even in SAFE MODE.
I can access Recovery Console booting from Flash Drive (bootable USB loaded with Win7).
I was “playing” with BOOTREC and BOOTSECT all day and I believe the BCD data is gone.
This is a SINGLE BOOT SYSTEM.
Inside Recovery Console, I have X:sources> prompt
I can go c:windowsboot type DIR and see 4 directories DVD, EFI, FONTS, PCAT but my knowledge reached a limit at this point.
Is there a way to BACK UP the BOOT data from a working PC with WIN 7 and transfer it to the one with problem?
Did you follow the article to the letter? And is your USB recovery pen also Win 7 64 bit? Because if it is 32 bit it won’t work. There is no way to backup the boot partition from another machine (well the way you want to anyway).
I think you have selected the wrong partition to mark as active. Follow the doc above and get to the point where it says “list partition” and tell me what it says.
Yes, I did. The USB has 64 bit version of Win7.

Hope you can see it.
SOLVED!!! Finally found the solution after many hours. Your guide is perfect and really help me. The problem was that the USB DRIVE was conected to a USB 3.0 port.
Waiting for your answer I still was using Google to find more info and found this…
Not directly related to your issue as you resolved it, but rather to your original description (particularly “The requested system device cannot be found.” on BCD operations despite all attempts to recreate/rebuild):
This error can happen if you are booting from a USB stick, and your BIOS supports a given usb slot, but the windows PE/repair environment does not!
I spent two days pulling my hair out, wrestling with this issue (the BCD store was ALWAYS unavailable with this “The requested system device cannot be found.” error, no matter what I did), only to find that the problem was simply the USB slot I was plugging my bootable USB stick in. By plugging it into a different (usb 2.0 instead of usb 3.0) slot, the standard repair actions worked fine.
Thanks again ! I completed your instructions after switch the USB to a regular 2.0 port and Windows 7 is back again. 🙂
Glad to have helped but I am little confused with your last post. Are you saying Windows was installed on a USB pen? Because I thought you meant you the USB had your Windows 7 installation media on it – as in you copied the contents of Win 7 installation DVD to it?
Btw I have another article about installing Windows 7 from USB 3 issue here
thank you this was right! saved me further grief!
Jorge just wanted to say THANK YOU for posting this. Just moved my USB flash drive from the 3.0 port to the 2.0 one and suddenly all the repair operations started working! Thanks!
Holy Crap! That worked! i was shocked!
This worked for me too! Amazing.
This guide should have a huge red sign at the beginning saying “ONLY USE USB 2.0 PORT IF USING A USB STICK”
Thank You very much for this!!!!!
Thanks dude.
I have used usb 3.0 on one usb 2.0 port. Switched to other port and it worked like a charm. Big thanks
Windows with boot problem was installed in a regular PC with 1TB hard drive.
Instead of a normal WINDOWS DVD, I used a bootable pen drive.
I connected that pen drive to a USB 3.0 port.
For a reason that I don’t know, that action gave me the error FAILURE WHEN ATTEMPTING TO COPY BOOT FILES when used the command bcdboot c:windows
The problem was solved when I connected the Pen Drive to a regular USB 2.0 port. and started all over again.
(sorry for my poor English)
The reason that USB 3.0 ports don’t work is because they require special drivers that come with a PC and can be easily downloaded from the internet. Since people with this problem can’t start up their OS, the port wont work because the driver requires an OS to operate. I had a similar problem a while back when I was trying to recover my Win 7 from an external Hard Drive, but kept connecting it to my USB 3.0 port like usual. Almost went mad trying to figure out the problem. The fact that USB 3.0 doesn’t work without an OS is information I will always remember and take with me to the grave.
PS: I know I’m replying SUPER late, just thought I would share the info.
Thanks a million. This guide saved my day, or rather I lost my day, but the night is saved! However, I also noticed what Jorge said about the USB 3.0. It didn’t work for me either until I tried the 2.0 port. Maybe a sentence about this could be added in the end of the article, just to save future persons a little pain. Anyhow, thank you! 🙂
Guy luk for 100 tools software. Insert it into ur cd rom right click on my computer click on properties click on hardware then click on any tin with question mark to drive 08067294481 for more information
You are an absolute life saver!!! Thanks bro!!!!
PERFECT!!!!
im gonna try but i dont have a w7 bootable disk. hope it works coz it takes me back to the black screen with the same error message. wish me luck 🙂
Hi there!
I get the error as mentioned at the top of the article:
“Windows Boot Manager
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1.insert windos cd and run a repair your computer option.
File: /boot/bcd
Status: 0xc000000f
Info: an error occurred while attempting to read the boot configuration data.”
But when I try to fix it as explained in this article, I get stuck after typing “diskpart”. Ik also get “X:Sources>” instead of “C:windowssystem32>” to begin with…
This is what my screen looks like after typing “diskpart” and entering:
“Microsoft Windows [Version 6.1.7601]
X:Sources>diskpart
Microsoft DiskPart version 6.1.7601
Copyright 1999-2008 Microsoft Corporation.
On computer: MININT-C2NJTAO”
That is all. From this point I am even unable to type anything…
Could someone please help me with this problem?
Thank you so much in advance! 🙂
Greetings from Belgium,
Inge
Great. Worked for me. Was having so much trouble booting my Panasonic CF-29 toughbook.
Im having this exact problem. Command prompt wont let me type..
I have the same problem, also from Belgium, lol =P
Thank y’all for dis time n date savin’ info which has worked out my problems successfully. But I happen to have an additional OS-ubuntu n tis not in os selection list n da command for additional os doesnt seen to recognize it, wht should I do?
Cheers!! You just saved me a hell of a lot of time!!!…I installed windows 8 as a dual boot but decided to remove it using easybcd which also removed the windows 7 boot but your solution fixed it,working perfectly!! Thanks again 🙂
Ok I have read and tried about everything for 2 days now, so here goes, maybe you nice people can help.
I turned my pc on and got windows boot manager
windows failed to start. a Recent hardware chage 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 administator or computer manufacturer for assistance.
File: BootBCD
Status: 0xc000000f
Info: an error occured while attempting to read the boot configuration data.
then it shows white bar at bottom of screen, has 2 options enter=continue or esc=exit
hitting enter gets black screen which gives you f2 for bios settings, which I have checked to make sure that bios are set to cd drive to boot from my disc, which by the way, does nothing but take me back to this original page with the error information
pressing escape gets balck screen with non flashing cursor, then bios with f2, then flashing cursor and back to error page, am unable to type anything in, to access command prompt mode, , inserting windows 7 disc i purchased when i bought windows 7 does nothing but go to bios setting f2 and then same error screen, i tried hooking up a different hard drive that does not have a windows system on it, so i could if all else format that drive and just use other hard drive as a slave and it pops up boot mngr not detected
You need to boot of the CD. From what you saying it sounds like this isn’t working. You need hit F2 and go into your BIOS. Look at the boot order and make sure your CD/DVD drive is number 1 in the list. If it still doesn’t boot from CD then it sounds like the issue is with your Windows 7 disk.
i cant find the CD/DVD for the boot, what i have to do now??? please help me out
Thankyou
Thank you thank you out of all the web sites I tried yours was the only one that worked thanks again.
Thank you for this information, it has been very helpful. I am getting the same error and I have the Windows CD, but my CD drive has not worked in a long time. The boot sequence is not recognizing my portable external CD drive and copying the Windows file to a USB stick isn’t working either. When I change the boot sequence to USB, then I get the error message ‘operating system missing’ and a flashing cursor. Can you help me get my computer running again?
Update – I removed all of the other files on the USB that I copied the Windows Vista 32-home installation files onto. I do not get the “operating system missing’ message anymore. Now there is a single flashing cursor line in the top right of the screen. The USB stick is lighting up like it is being accessed, but nothing happens. I have tried both of the USB ports on the laptop as well as running it through an external USB hub. No difference — nothing is happening. Thanks again for any ideas.
Did you install the ISO image correct to your USB? Because you can’t just copy the contents, that won’t work. Try this tool and let me know if it works http://www.informationweek.com/byte/howto/personal-tech/storage-memory/231000246. If you don’t have the ISO file you will need to download another tool that can create a bootable USB Vista image from your Vista CD.
Thanks D.A.R.Y.L. — you pointed me in the right direction. I had to make an ISO image from my DVD … I followed the instructions and used the programs described here: (http://www.vistax64.com/tutorials/181538-usb-bootable-vista-installation-flash-thumb-drive.html).
I am writing this from my laptop which is up an running like normal again. Thanks very much!
I have an acer aspire 4741z notebook.when i try to start my laptop i face the problem that is “0xc000000f.boot selection is failed.”i try to flow your instruction but i see failure attempting to copy boot files. Please help me
If you get the error that the boot files cannot be copied, try selecting the partition like it says, the small partition that used to be the Bootloader for windows. Make sure it’s active first and then type “format” and hit enter. This got me to the point where booting from windows disk actually showed the windows 7 system. It immediately asked me to restart after it found it. Then when I got back there I did the standard recovery option and got back windows 7. Just use Linux disk to repair grub if you want it. I use “boot-repair”. There’s a great link on the Ubuntu site if you Google “boot-repair”.
Yeah I tried this but my partition size for Windows is only 100mb… Any ideas as to why this may be?
Not sure exactly but there are cases where it is 100MB. Possibly be because it is a pre-installed laptop/desktop branded?
I only have two partitions. A 582 gb and 13 gb. Please help?
Right in the beginning, when I put in diskpart, it all works, then I put in list disk and it just says “There are no fixed disks to show.” Please help!
Heeeeeeeeellp I have a 64GB ssd with windows 7 on it and a 2TB data drive. When I start windows it tells me their is not boot sector thing. When I check for the disk partitions it only shows a 59GB partition on Disk 0 (Boot ssd) and no 200MB boot sector. I checked disk 1 and couldn’t find it their either but I don’t think it would be their. How do I make a new boot sector so I can do these commands to fix it? Please help!
You can have the boot disk/sector the same disk has the OS disk, it sounds like yours is setup this way. Just run all the above commands on on your 59GB disk instead and it should fix it.
Wonder if you can help. I’m running W7 64bit with a single drive with two partitions and I have checked to make sure that the boot is set to active. I’ve completed all the steps above, very helpful thankyou, and it states that it was successful prior to reboot. However, when I go back into the command prompt it is still not showing an operating system which I’m assuming is why it will not allow me to point the bcdboot to a windows folder. I have even reformatted the active directory and carried out the steps again but with no luck.
I do have the orignal windows OS as it is a dell PC but I don’t want to have to reinstall it all and lose all the data unless it is a last resort. (It’s my daughter’s PC and she has lost of “stuff” on it that she doesn’t want to lose).
Any advice would be most welcome – am I at the point of reinstalling the entire OS and will this work given that it doesn’t see the volume?
You shouldn’t have formatted any of the disks unless you were 100% positive what was on it. It sounds like you have deleted the OS disk by accident. You need to find the Windows folder on one of the drives, this is the OS disk. If you can’t find it on any of the disks then you formatted it and you will need to do a full re-install but you will lose all data.
Tks, it wasn’t the OS drive as it was only 100mb that i formatted. However, the recovery console doesn’t find any OS and i’m unsure of what drivers to load at this point and what they’re called. I have attached a different int hard drive to check everything else ok and that works fine with a new OS installed but its her data that i’m trying to save. Is it worth copying the bcd or mbr and putting this on the faulty drive?
The whole point of this article is that it will rebuild your boot partition from scratch. The reason you can’t see the OS from the RE is because it looks at the boot partition to get this info. Have you tried the guide yet? Because at no point do I say try to do an automatic repair, this is guide is meant to tried after the auto recovery fails.
Tks for coming back to me. I have followed the guide 6 or 7 times to no affect. The issue that I have is that when i run the bootrec commands which say they are successful and then reboot and try to then run the bcdboot from a windows folder I cannot find the windows folder. When I look in my C drive it is only showing a Temp directory with no other files and when I go intothe directory it shows a bcdinfo.txt file, bootfailure.txt file, disklayout.txt, srttrail.log and that is it. My D drive is my CD drive and the only directory showing is the X drive which I assume is produced from the recovery console.
Well you have deleted your OS partition. I know you think you haven’t but you must have. If you can’t find any partition with the Windows folder on it you must have deleted it. You might as well just re-install from scratch.
Hello…. Im using vista and this is what is the problem exactly….
My pc wont boot anything, not the OS, not the recovery disk from CD or USB, not the installation disk that came with the laptop, not any other OS’s bootable installation disk…. NOTHING AT ALL…. It doesnt boot with any boot options… Give the error “systemrootsystem32configsoftware absent corrupt” trying to boot windows normally, give an error “0xc0000225 bootbcd vista” trying to boot recovery disk from usb, doesnt even read the recover disk (on cd) and doesnt even read the installation disks…. So…. how can i ever get to any sort of recovery thing from any source for this….
Ok what if I get the following… BFSVC: Failed to open handle to resume object. Status = [c0000034
On the part where you said The Windows 7 boot partition is a 200 MB primary partition. My partition was 100 not 200
Thankyou sooo much this fixed my problem.
Spot on. Thanks a million. You help my lecture classes, had this error could not fix and neither was ma students. Thank you.
Thanks mate. You saved notebook taking a leap from second floor window.
How to fix the below issue:
File: EFIMicrosoftBootBCD
Status: 0xc0000225
Info: An error occurred while attempting to read the boot configuration date.
Is this issue related to boot files? If yes how do I resolve this issue.
Help will be greatly appreciated.
Thanks
Please HElp ME NOTHING WILL BOOT ON MY LAPTOP NOTHINGGGGGGGGGG
hi
i have acer aspire.i want to reinstall my windows with recovery disc.when i press alt+f10 it shows acer ercovery managment page shows a message plz wait a moment..execution start but it never end.plz help me.what can i do?
such great and helpful information… i thank you from the bottom of my HDD
Please Help. I’ve followed instructions above but my partition info is different from above. It is a Dell laptop. I also can’t read D: (I/O device error) which I assume is why my boot disk isn’t helping. I get to safe mode via a USB w/ recovery files I created from a different laptop running the same OS (Win 7 – 64).
Anyway, my list partition info follows:
Partition # Type Size Offset
————- —— —— ——–
Partition 1 OEM 101MB 31KB
Partition 2 Primary 19GB 104MB
Partition 3 Primary 679GB 19GB
Partition 2 was/is Active, while 3 is not
And when I try bcdboot x:windows I get Failure when attempting to copy boot files,
and when I add /s c: I get
BFSVC: Failed to open handle to resume object. Status = [c0000034]
Dell didn’t seem helpful and are sending a technician to swap hard drive on Tuesday. Please help me avoid this if possible.
Much love, this helped fix my laptop and a friends. Thank you so much.
Hi Daryl,
I have got a problem with my Win7 64 boot indicating above error with BCD. I tried to apply your fix, however after I signed the former systém partition ( it said the disk was health however no system found and also no NTFS but RAW File system? ) After I made this partition active to proceed to NeXT step and restart the repair Win DVD, I am getting black screen with no options, no promt command line accessible. I tried to restart again but still receive the same
what do you mean, you signed the partition? If you did this you have likely wiped the entire disk
Sorry for not being clear enough, by “signed” I meant selecting the primary partition where was Win7 installed and making it active. After this step I got stock and even my Recovery DVD does not work, when I boot, I get the failure notice that HDD was not readable. I think that my HDD is damaged in this partition apparantly

After this step I got stock and even my Recovery DVD does not work, when I boot, I get the failure notice that HDD was not readable. I think that my HDD is damaged in this partition, Hope my data saved in different disk partition will be saved and possible to Recover from another HDD which I borrowed today to diagnose this damaged disk.
Worked like magic… Thank you so much…
I’m having this problem but mine is going a step further. When I put a disc in it won’t read, the drive tries to read but never starts to spin. Any suggestions?
Last day I installed the Windows 7. I found out that my other disks (partitions) automatically disappeared from my computer and only showing C disk.
I tried to defragment, hide/unhide the disk, also cmd » diskpart » list volume but still can’t see any trail of my other disks.
But when I go to Device Manager and check Disk Drives » Volumes » Populate, I can see that there is:
•Disk: Disk0
•Type: basic
•Status: online
•Partition style: Master Boot Record (MBR)
•Capacity: 305245MB
•Unallocated space: 0 MB
•Reserved space: 0 MB
•Volumes only shows
•C: 305245 MB.
How can i resolve it, please help me.

To fix this the easy way just install windows 8 and you will have no problems at all. From windows 8 you can revert back to windows 7.
the hard disk status is showing invalid in dos window
Hello, I got the same issue as you originally did and I followed your instructions to the T but now when i booted into the OS, it loaded fine but everything I had was now missing….Is there anyway to get anything back? I did not know that this will erase everything… Please help me 🙁
it doesn’t erase anything, look at other people’s comments; they haven’t had any issues.
Did you try to create a dual boot system previously? If so it could have amended the boot disk to be this new install
Hey can you help please? When I type bcdboot c:windows it says there was a failure when attempting to copy boot files. I have a netbook, so it does not have a place to put a CD, therefore I am using a USB. So, what do you mean “Make sure your boot partition is set to Active Boot from your DVD”? How should I have the BIOS Setup? Should it be set to the regular settings? Also, does it matter where I have the USB put in? I haven’t been able to use my netbook in over 2 years, please help?
Thanks a lot! Your article gave me a great help
thank you so much

Thanks
I dont have a disk that iš 200 mb
read the other comments about looking for a 100MB one instead or alternative methods.
mmwaaah! u dont kno how much you helped! thank u. advice. fixer need to know whether to type on diskpart mode or resource mode.
when executing bcdboot d:windows via usb should be connected to usb 2.0 mode not usb 3.0.
and that too not helped try replacing d
nice helped me a lot….
if it doesnt helpd you in 3rd stage i.e., “bcdboot d:windows” stage, it is usb connection fault change it from usb 3.0 port pin to usb 2 port pin in bios screen. i.e., as follows
bios->system configuration->usb 3.0 configuration in pre o.s to (auto).
even if it doesnt copy, try changing drive letters 🙂
My window7 laptop,doesnt want to install windows,it shows error on disk configuration,plz help guyz.

Hi there,
I have a similar problem and would appreciate some help ASAP please. I have the following error File: BCD Error Code 0xc0000034, I cannot boot the laptop at all, it lets me go into the BIOS but I cannot boot from disc (as notebook doesnt have one) and my Windows was downloaded so dont have a USB with Windows 8 on it.
HELP!!!!
if you have windows iso and access to other pc and usb drive or email me for iso [email protected]:
1)download Linux live usb and install
2)copy the boot folder from the iso using winzip or mount the iso file using deamon tools then locate the boot folder
3)copy the boot folder to the live usb
4)boot the live usb on the BROKEN machine
5)locate the Boot folder on the broken machine not from the disk, usually in C:Boot or in your recovery partition
6)open the location and then open a new window with the folder from the cd
7)copy the bcd from the cd’s boot folder to the broken machines boot folder
8)shutdown
9)remove live usb
10)boot
11)all fixed!!
This was an absolute lifesaver. Thank you so much!
U saved my life! Thank u so much!
Bcdboot with /s DRIVELETTER parameter can help
Some erros mentioned here!
I am trying to understand how my systems are getting into this state in the first place. I am deploying Windows XP using WDS. The first time I deploy the image, it’s fine. If the system requires a re-image later (because the machine is being issued to another userfor instance), I get the missing file BCD error.
No idea what you are doing but that doesn’t sound right.
The BCD error is related to Windows 7 not XP so somehow you are installing a Win 7 boot loader with XP; that is your issue.
You have no idea how i’m grateful ty soo much
best way to fix this is just formatting your drive through your windows cd setup PS (if you do so you will loose all your files!!!) just reinstal windows people!!
Than. k you sooooo much this worked perfectly

“Windows Boot Manager

File: /boot/bcd

I have this currently: http://s1148.photobucket.com/user/TheVoicz/media/20130907_002603_zpseba99fe6.jpg.html
Where do I go from here?
read the end of the article where i mention about having an EFI partition, there is a link there for your issue
hey i done what u said…but now its showing missing operating system..:(
what is the solution now? 🙁
(1) boot computer from installation disk (or USB/SSD drive with istaller on it)
(2) conceivably you have another partition with some operating system where you have an image of the operating system installer package, in which case boot from there
BRILLIANT!! Really got me out of a hole with this article, thanks a million.
hi D.A.R.Y.L, i am going to try your tip on a dual systems PC, Windows 7 64 bit and Windows 8 (don’t know if 32 or 64 bit), that give the \Boot\BCD error. May be Tricky, i will relate you about, after.

Hello!
I’ve done all the steps.
My Win. partition is D.
But, i type bcdboot d:\Windows , hit Enter and then “Failure when attempting to copy boot files. error is shown.
(I tried c:\ too. But same.)
What sould i do now?
I have Fedora 20 Linux on an SSD and retain Win8.1 on the HDD of my desktop. So I switch the boot order to select the OS.
Win8.1 stopped being able to boot and gave the message that got me here.
The HP recovery stuff was useless, scary, and slow. Automatic repair took over an hour to decide that it couldn’t do anything. With no feedback except for rotating balls like Captain Queeg.
In the end, I fixed the Win8.1 from Linux:
mkdir -p /other/efi ## make a mountpoint for the other disk’s EFI partition
mount /dev/sda2 /other/efi ## mount that partition
ls -l /other/efi/EFI/Microsoft/Boot/BCD* ## figure out what was going on
There was no BCD but there was a backup. Create a BCD from it:
cp -p /other/efi/EFI/Microsoft/Boot/BCD.Backup.0001 /other/efi/EFI/Microsoft/Boot/BCD
Now Win8.1 boots.

Make a bootable usb disk that includes windows10.iso (it doesn’t matter if you are using another windows version.
Then turn off your pc
And plug it.
Then start your pc and hit your key to the bootmenu. It should be F12. Then select your pen drive. Dont select any other device. And dont be afraid of others.
Then windows logo will be pop out.
Then select country and hit next.
Then click repair your computer.
Then click troubleshoot and advance and command prompt.
Then type
Diskpart.
Then type list disk
Then you will see your hard drive and pen drive
Hard drive will be disk 0
Then type select disk 0 ( can be different with your pc)
Then type list partition
Then you will be able to see a disk with 200MB or a disk with megabytes not gigabyte. Then select partition …..( the number of that 200mb disk)
Then type detail partition.
Then type active.
If you doesn’t see a megabyte drive just type exit.
Then you will again going to
X/sources…
Then type bootrec/fixmbr
And enter
Then type bootrec/fixboot
Then wait 10 seconds.
Then type bcdboot c:\windows.
Or bcdboot d:\windows.
You are done…
Type exit and you will see continue to windows 10.
Done….
Its not must be windows10.iso
It doesn’t matter if it is a another windows iso
Please make sure that you are plugging your usb stick to a usb 2.0
Bcoz usb 3.0 drivers not working in boot
You are really genius ! saved me as well without loosing files

laptop asus x452c windws7 x64
saya punya masalah. stlh dualboot windows7 x64 dengan ubuntu. lalu partition ubuntu saya hapus manual lewat disk management. kemudian setelah restart compter ada pesan
“error: no such partition.
grub rescue>”
lalu saya pakai bootable usb wind8.1 x64 untuk mengakses menu repairs, cmd.
saya langsung ketik perintah berikut tanpa melalui tahap yang seharusnya
“bootrec.exe/fixmbr” enter
“bootrec.exe/fixboot ” enter
“bootrec.exe/scanos” enter
“bootrec.exe/rebuild…. ” enter.
lalu saya restart
lalu muncul bluescreen. dng tulisan
“File: /boot/bcd
Status: 0xc000000f
Info: an error occurred while attempting to read the boot configuration data.”
dan ada perintah seperti UEFI atau …..
jadi apa yang harus saya lakukan sekarang. saya masih sangat pemula. jadi masih kurang paham. mengenai stepbystep. jadi saya mohan bantuannya.
F***ing awesome description. I just saved our Server 2008 R2 Server and the SQL database it is running.
Great. Thanks a lot.
Infinite thanks!
I’ve been trying to repair my os for five days now and finally found a guide that solved my problem!
I can’t thank you enough; you saved from format precious data I have in my HD.
Cheers from México! Five stars.
Mine was an HP laptop, and not a dual boot, but using the first section of these instructions solved it!
This part worked.
bootrec /fixmbr
bootrec /fixboot
After that, I couldn’t get the bcdboot command to work, but I was able to use the recovery console to successfully run a startup repair, which had not worked before.
Thanks!!!!
Thanks so much, this got me up and running again. Bios had reset itself for some reason, I don’t know why, I went to turn on computer and bios presented a checksum error and loaded defaults. I have two hard drives set up with raid mirroring and the bios checksum error defaulted raid back to ahci. I selected raid again in the bios and the two hdd’s were mirrored again but got this boot error. In my case my WIndows 7 boot partition was only 100mb and was already active when I looked in diskpart. It was there commands that solved the problem for me:
bootrec /fixmbr
bootrec /fixboot
bcdboot d:\windows
The usb 3.0 to usb 2.0 worked for me too. SAMSUNG NP905NG3, system win7 pro spanish version. Boot failed with common code 00000×0..
Put the usb into usb 2.0, repair disk auto and it worked.
Thanks a lot guys.
Thank you so much for your solution to the boot problem with windows 7. I had broken the RAID array and I was turning the mirror drive into a simple data drive. Only you described the partition fix and the bdd transfer necessary. Do you have a website for tech support?
Thanks very much, man. I’ve got a problem with my windows and Linux mint, and you solved it. Linux is not working more but I’ll fix later.
Great Tutor!
Thank friends USB replaced 3.0 to 2.0 formula is worked for me thank u allot friends again.
Fixed boot-bcd-0xc000000f-windows-10 successfully, followed your advised steps
bootrec /fixmbr
bootrec /fixboot
rebooted the machine again into the recovery console and typed “bcdboot c:\windows”
Problem resolved
THANKS
bcdboot path to your windows folder didnt work it says couldnt copy files or something but then i decided to try to load windows and it worked thank you so much
such a wise solution. Thank you very much. USB 2.0 usage made my work.
I just had this problem and couldn’t find a solution until this article. You’ve saved me a lot of time and headaches, thank you!
Thank you very much, just what I needed. I changed my active partition and crashed my bood section. With diskpart I managed to set the Windows real active partition and booted back like normal. Thank you again, will definitely need to remember those cmd commands!
FYI I was having significantly problems with the last step of this tutorial. I tried many alternatives, and it ended up being a case where (for whatever reason) running this from the Windows PE environment off my usb drive was the culprit. Running Win PE off of an old fashioned DVD made everything work for me. No, this was not a USB3 problem (this machine does not have USB3 ports) it was just a problem booting off a USB entirely and trying to run through this process.
If it isn’t working for you, try burning a DVD and loading that way.
Im having issues with copying the boot files to C:\windows..its failing….I can confirm that C is the boot folder for my laptop….its working if I copy it over to D:\windows but of course it will fix the issue ( did this to test if the copy is working)
All my USB port are 3.0….is there any way around this…?
Correction…3rd line
* of course it will not fix the issue

The described Command Line procedure works fine on my HP7900 Windows 10 Home.
I luckely had my 1 year old repair DVD, that won’t repair but allows you to get into the Command Line X:\. Then what also helped me, is that long time ago I have put a subdirectory in the correct folder; I named this subdirectory 1_Windows_10_installation so I could easily find out which folder I needed. In my case the final command was: bcdboot f:\windows
That worked: “boot files succesfully created” and after that the PC started well and all was as the day before when it still was OK.
hay thanks a lot lot. me pc was dying now got saved
I made one of my partitions active, 3rd one, the list was OEM part, second one primary and 3rd primary. I had no idea which is what, first primary was already active, the second one wasnt so made it active then restarted. Hoping to go into the next part and do the bootrec commands, but on re boot, my recovery dvd no longer taking me to the recovery menu, all i get is black screen! now i cant use a command prompt anywhere on my pc!! i must of done something making the wrong partition active, but why would affect a cd boot up? … on flip side the lost f8 safe mode screen now loads when i boot from harddisk, previously lost this menu when trying to do bcd edit back up method. but was getting boot/bcd error screeen…, how can i get into prompt command now…. none of the bios menus let me, safe mode doesnt work as says the windows config system32 is not right.
