Boot Configuration Is Missing Or Contains Errors
Apr 9, 2013
Firstly I created a partition of 1 GB on my 128GB OCZ Agility 3
Then I used bitlocker to encrypt it, and then for some reason when I tried to reboot the computer after doing the aforementioned, I get the message that windows cant boot, because the boot configuration is missing or conatins errors
I dont see how BitLocker and Disk Management can screw something up so much so that they either deleted or encrypted my boot config rendering me unable to boot up the computer.
What I did was shrinking the c:drive by 1000mb then formatted and partitioned those 1000 mb into a new drive. Secondly I encrypted the 1gig with Bitlocker with a short 12-character password.
I am now unable to boot up my laptop.

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: BootBCD
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 unreadable. I need my c drive recovered.

I booted in recovery mode but I can't make a system recovery drive on a USB because it says the boot files are missing. And I don't have a recovery disk because SAMSUNG ATIV 6 doesn't have a disc drive. I've been searching the web for a recovery disc download to no avail.

Alright, so after restarting my Toshiba Satellite L50A16H Laptop (Windows 8.1) it gave me a blue recovery screen,
it stated:
The Boot Configuration Data file is missing some required information.
File: BCD
Error Code: 0xc0000034
Unfortunatly I haven't made a backup or recovery file to boot my computer from so I'm stuck with the issue of finding a windows 8 iso file that matches my system, i tried getting the windows 8 iso from microsofts website but it asks for a product key before it lets you download the file, the problem is that my product key is built into the laptop and Toshiba has not provided me with the key on a sticker on the bottom or through any other method. apparently its built into the BIOS. i have a 16gb USB stick that i can boot from. using a key finder is obviously not an option because i cant start up the laptop. I was also wondering if i manage to find a windows 8 iso file to boot from, will my toshiba laptop automatically fill in the product key for windows 8 as i dont have it.

The computer is an ACER Aspire 3. 4Gb RAM. 500Gb memory.
I've been using the computer for a month and a half more or less and everything went OK only few small problems but 2 days ago. It did not Boot.When starting the PC the following appeared:
Recovery
Your PC needs to be repaired
The boot configuration data file is missing some required information.
File:BCD
Error code: 0x000000d
You'll need to use the recovery tools on your.....
The first thing I did was creating a bootable USB with Windows 8 software, it did not work. SO i used Rufus, it worked and launched the Windows 8 installation and recovery but when I tried to recover, refresh, anything it told me the disk was locked... or anything the only thing I'm able to access is Command Prompt.
I've been trying some commands that I've seen online but no luck so far. Some commands tell me "OK, successfully something" But when reboot and I change to default the boot order and UEFI then the same error appears.

I try different setting in setting utility (after pressing ESC) and nothing changed.
I dont have any USB or Disc with windows. (but i do have legal copy - it was already installed in my PC) so i cant restore pc from installation media.

Earlier, about an hour ago, I left to go job searching, and left my computer in hibernate mode so I could bring it back up as soon as I got back. When I tapped keys on the keyboard, the computer powered up as usual, but it brought up the BSoD, stating it was missing files.
Prior to receiving this error, everything was working fine. I even set it to hibernate mode during the night, and it powered on this morning without any problems. I dunno if it's the multimedia keyboard I'm using or what that caused it.
I don't have an installation disc (since I bought it from Fry's Electronics about a year ago with 8 pre-installed), and neither do I have a recovery disc (since I didn't know how to make one.
Computer info: Windows 8 x64
Manufacturer: ASUS
how to fix the missing boot files, and how to do it without causing any data loss from either of my hard drives.

In the Windows XP-times we had a program called "bootvis.exe" that was really good finding programs, drivers aso that kept WinXP from booting fast.
Is there a program like that for windows 8.1?If not, how do I find the thing that keep my boottime on 43 sec from a Samsung 840EVO? (Boottime is WITHOUT POST-time!!)After about 9 seconds in the boot-process, the screen turns black, and all HDD-activity stops. A very tiny blink about every 7 seconds for the next 30 seconds, and then the Welcome-screen is shown, and boot continues normally.
I have tried to uninstall Bitdefender, no difference
I have tried to disconnect all USB except mouse and keyboard, no difference.
I have looked for new BIOS (there is none), new drivers for the complete PC, no difference.
What can I do to track this error down? To me it looks like Windows is waiting for something, that after a while times out ... but what is it? And how do I find it?

I had been running windows 8 for a while, and within the last month I installed a new video card (Nvidia EVGA GTX560ti), and a new SSD (OCZ vertex 4 256GB). While still running Windows 8, I had been playing games, doing a lot of photoshop work....and other various CPU intensive things. I was editing photos one day in photoshop CS5 , and I noticed that the program became somewhat slow all of the sudden (basic tasks that used to be very quick and painless). The program eventually became unresponsive and had to reboot the computer. Upon restart I got all sorts of "boot drive errors", and unreadable boot disk errors.
However, these errors only seem to happen randomly. I checked my CPU core temps, and while doing the regular work I do on the computer, all 4 cores averaged about 92 degrees Celsius! I ran a virus scan, for something unrelated, and I checked the temps and they were spiking 98 to 100 Celsius!!!! While im just using the computer regularly they settle around 65-70. But if I do ANYTHING slightly intensive, I could probably cook dinner on my heatsink. I guess my main question is WHY am I getting boot errors, and why do they seem to happen randomly. I suppose the motherboard could be fried, im really not sure. This happened in the past, and reinstalled windows 8. After a couple days, same story. I'm almost positive this is a hardware thing. My first priority is of course to lower the CPU temps however I can.

I recently updated to win 8.1 after I just got my freshly installed win 8 lenovo ideapad U510 back from the repair depot. The following errors occured that I can remember:
Kernel Security Check Failure
Bad Pool Caller
Driver Corrupted Expool
Most of it seems to occur when turning my wifi on and off, but it's happened plenty of other times right after booting as well. I have attached the diagnostic tool files ...

I bought a new laptop 350gb HDD with Windows 8 64bit preinstalled (no disc came with it) however I needed win7 32bit for my job since the softwares used are only compatible with old win version. I managed to back up my Windows 8 before I partitioned my HDD into 3 drives and installed win7 ultimate 32 bit on a different partition. I remember that my Windows 8 was installed in Drive C (100GB) while I have 80+GB for Shared files on Drive E and the rest of the memory are for Drive D where I installed win 7 and I labeled each drives accordingly. At first everything was working fine on both O.S, it was giving me the dual boot option at start up but I forgot if I really have tested running both O.S. before I gave my laptop to my supervisor and asked him a favor to intall the softwares for work purposes.
My supervisor then approached me and said that there might be some incompatibility issue with the updates I have on my win7 coz some applications don't install so he asked me if its ok if he reinstalls a new win7 so I said yes since Im confident that its will work fine and I have backed up my Windows 8 anyway, in short, I left everything into his hands. Later, he then got back to me and told me every job related softwares now work except that my Windows 8 now doesnt show and yes, dual boot option is not there anymore and it boots automatically to win7 like Windows 8 is not there.
I've read some forums how to check if your O.S are still there and it could just be a boot up issue and use of Easy BCD might work. I have attached images below for your reference. Now what I'm confused of is that my Windows 8 appears to be in Drive D and win7 could be in Drive C, which I'm thinking if they were exchanged when my sup reinstalled win7 or he may have overlapped my Windows 8. Im pretty sure he knows which drive is for which O.S since I labeled them. Now Im afraid to use EasyBCD on the wrong drive and I cant approach my supervisor anymore to bother him again since he worked on my laptop for almost the whole day at work.
- if both o.s. are still intact and recognized
- why the Drive letters got mixed up and how to check which drive has which o.s coz it seems like both drives has a part of my work related applications (didn't put personal files yet on win 8 when I had both o.s installed)
- is Drive D really is my Windows 8 now?
- does Easy BCD really work
- how to use Easy BCD to get my Windows 8 to boot up to or both of them to show at start up without corrupting my work related softwares

I have looked around a bit and all solutions to this problem require me to get into the startup screen when booting from the installation disk upon startup. The problem is I cannot get to that screen!!
I am a uni student and can download windows 8 OS for free at msdnaa, I have done that and made an image file on a dvd and usb stick. I then put both of those into my dell N5010 (which is running win 7 now) and try to access them upon startup, (I go into the boot menu and try booting from booth DVD and USB) and both times I just get the error "boot manager is missing press ctr, alt, del to restart) so I cannot even get into the installation screen to do the repair that is says I need to do on all the other solutions I have seen.

Have a Gateway Desktop. Upgraded from 8 to 8.1.
Somehow I disabled the disabled Password Logon and its back asking for a password at boot.
Owner doesn't remember original password when setup.
I have a password blanking cd that I've used on both 8 and 8.1 pc's.
The problem is I can't boot from the CD and I can't, obviously, use that wonderful new setting, "Update", "Update and Recovery" and the option to boot with USB, CD etc. since I can't access the OS.
I have the BIOS set for the CD/DVD drive for first boot however boot options only show the "UEFI: ST....." drive.So I can't boot from within or without.

I've got a windows 8 laptop which gives me this error message when i try to switch it on:
"Your PC needs to be repaired The boot configuration data file is missing some required information.
File:BCD Error Code : 0xc000000d ............................" I'm sure you are all familiar with the rest of this dreaded error code.
I've tried all the repair options, recovery disks to a windows 8 bootable flash disk, the command prompt fix boot commands as well but still I get the same error message whenever i try to boot windows.
Now I'd like to know, can't i just copy the boot folders from another similar windows 8 pc and paste them into my harddrive to fix this?

I am having a problem with a new Dell Inspiron 15 3520 that came with Windows 8 installed and that I had been using for only a month when it went bad.
The problems started when I turned it off about ten days ago, and went I turned it back on a couple days later, and it was stuck in the apparently famous Windows 8 "Automatic repair couldn't repair your pc"/BSOD loop. I was not able to boot into safe mode. System restores made no difference. Somewhere along the line I found something that said that I had an "inaccessible_boot_device error".
From the repair menu maze, I was able to get to a command prompt. I used this to copy almost all of my files off of computer.
Chkdsk showed no bad sectors, no bad partition records, or other irregularities. sfc returned "Windows Resource Protection did not find any integrity violations". Some test (I do not remember which) showed that the boot record and BCD were fine. The Dell hardware diagnostic test showed everything working fine.
I am thinking that it is possible that the source of this was a virus or mechanical problem (I saw no evidence for either). If I had to guess, however, I would imagine that the computer stopped working after an automatic update pushed a corrupted/incompatible driver. I have seen discussions online about people having problems with NVIDIA video and/or SATA AHCI Controller drivers, and Windows 8 getting corrupted and stuck in the BSOD loop from that. At some point I saw a Windows Update Log (I am not sure where), that showed that, as Windows shut down the last time it was functional, automatic updates installed a new AHCI driver.
I tried downloading some new drivers for the 3520 from the Dell web site and installing them on the dead computer through a thumb drive and the command prompt. The downloads are all executables, however, and when I tried to run them, I get the message, "the subsystem needed to support the image type is not present". I believe that this message means that the driver executables are 32bit apps and won't run from a 64 bit command prompt. I also tried to use the "Drivers and Utilities" disk that came with my PC to do some driver rollbacks, but, I can't understand the file names or folder structure on the disk, and, when I try some to run some of the exe files ("setup.exe", for example) to get a gui interface, I get the "the subsystem needed to support the image type is not present" message.
After working on the problem for a while, I borrowed a friend's Windows 8 installation disk set. The computer will boot to the repair options off of the 64bit disk, but not the 32bit one. I did attempt a System Refresh off of the 64bit disk, and got back the message, "The drive where Windows in installed is locked. Unlock the drive and try again."
Around the time that I was messing with the BIOS settings to get the computer to boot off of the Windows 8 disk, I started getting a message "Your PC needs to be repaired - Boot Configuration Data file is missing some required information -- File:BCD -- error code 0xc0000034" at the start of my boot ups. I am not sure if I deleted a file somewhere during my repair efforts, or if I am getting this message because the computer is confused in efforts trying to boot off of the DVD. I get this message even with the DVD removed and the BIOS set to boot off of the Windows Boot Manager, however, so I am guessing that a file is now missing. And the message stops me from getting into the repair menus/command prompt any other way except through the installation disk.

I have a Dell 755 dual core, I loaded win 7 had a problem was with my CD rom, on boot up it was there, in devices it was there name and model, but as soon as I put CD in and opened the CD it would disappear off the machine sometime it would read what was on the disc and then disappear, I asked many question nobody gave me an answer. I installed it on a Dell 270 it works great.
Now on Win 8, the problem I have is if I have my mobile modem in the usb when I boot up my CD rom doesn't appear, if I take the modem out and boot up my CD rom is there with the drive letter G, when I put the modem in the CD remains and works correctly.

While I was messing around with my laptop, I decided to add on a fourth operating system, Arch Linux. I suppose I was pushing my luck a bit . Anyways, during the installation, I accidentally deleted the EFI system partition from my laptop, which contained the Windows Boot Manager and necessary files to boot. Great. I only made things worse by trying to troubleshoot, and broke grub as well.
I have a Windows 8 repair disk I made using the Windows 8 built in utility, but it does not boot: the computer turns on, and just hangs at the Toshiba splash screen.
I also can obviously not access the Toshiba recovery partitions, as they are booted into just like Windows itself.
I found a bootx64.efi file on one of my system's recovery partitions (Toshiba seems to have some really complex system going on) and placed it in EFIootootx64.efi. According to this site, FGA: The EFI boot process., I need to place the bkpbootmgfw.efi (on my system, that was what it was called, but I suspect boot-repair (ubuntu tool) messed something up when I was first setting up grub and the ESP and the bkp stands for backup) back onto the EFI System Partition.
Where to look for in the various Windows Imaging Format .wim and .swm files I have laying around my recovery partition(s) in order to extract the necessary EFI files. Any Windows Repair iso that works.

So I created a brand new user in Windows 8 using my MSA. And I set it to set up as a new PC so that it wouldn't carry over themes or any settings from the previous computer. But as soon as I signed in, it had all of my old settings, themes, and configurations from my old computer.
So how do I set it so that it goes back to all the default settings like a brand new user logging into Windows for the first time?

I bought a new lenovo laptop with built-in windows 8 OS. Just after a few days I started using it, networking problems arose. When I tried to connect to a wireless router,it shows connected but could not browse even. Troubleshooting gives a message that "WiFi does not have a valid IP configurations" or "Problem with wireless adopter and access point" or "Network cable is not properly plugged in". I contacted Lenovo chat support and tried re-installing the latest drivers, but couldn't solve the problem. i still couldn't connect to the wireless network properly.

Cisco access point using DLINK router w/ DHCP 192.168.0.X
Problem:
New Toshiba notebook connects to Verizon router without difficulty, but cannot connect to DLINK or CISCO without "LIMITED" usage (IP configuration error) [With a lot of reset, renew and Windows 8 troubleshooting it will connect to the DLINK for about an hour, but the magic must be repeated after an hour or so]

Is it possible to configure Windows Store so it'll only show free apps or showing without the picture? My internet connection is not that fast and every time I tried to browse, it takes few seconds to load up a page, if I can just display types of apps (free, etc.) or list apps (without icon/picture), it'll speed up the loading time, but I can't find anywhere to configure this.

I have a brand new PC workstation.
Everything was fine, until recently, when I turn on my PC, I don't get an immediate internet connection. This is happening nearly everytime now with some frequency.
I reset the router/modem and everything is fine after that, so all is good.
But it is still frustrating. I get, "Ethernet doesn't have a valid IP configuration".
Following are screenshots of my 'ipconfig' and 'Network Connection Status' before (unsuccessful) and after (successful) internet access:
You will see from the above that there is certainly something different with the data...
Incidentally, I did find a nice youtube 'tutorial' in relation to this subject title about manually configurating the settings:
I haven't tried this yet and that is probably down to the fact that I can't find my alternate DNS server setting (the very last box to fill in - watch the video and you will know what I mean) ???

For some reason System Configuration's Startup Selection is stuck on "Selective startup". When I change it to 'Normal startup" and close ad then reopen System Configuration it reverts back to "Selective startup".
Also, not sure if it's related, maybe once out of every 4 or 5 boots Windows 8 starts to the Desktop instead of the Start Screen. This is a relatively new install.
