Windows Update Error 0xc000021a Installing Build10041

Question: Windows Update Error 0xc000021a Installing Build10041

I booted my backup PC with Windows 10 Preview on it after seeing the availability of build 10041 announced. The update was there along with a lot of other invalid updates. I boot up WIN10 at at least every other day to see what's new. So I was surprised see so many of these other updates. Many of them were for Intel HD 4600 graphics and ASUS Bluetooth hardware that would be imbedded on the MB. But my Win10 PC is AMD based and has AMD Radeon 3300 on-board graphics and no on-board Bluetooth. The strange thing is that those updates that cause the error are appropriate for my other main PC which is ASUS Z97-PRO and Intel i-469K based with Intel on-board HD4600 graphics... and ASUS on-board Bluetooth. It's spooky but it is as if windows update is confusing its search with my other Windows 7 PC. In WIN10 9926 Windows Update you can't decline an update that the system finds for you.

The system suddenly does a restart and then it can't find the C: drive. I have to power off the power supply for 10 sec and restart to get back to being able to see the SATA1 drive. I had to work through three cycles of those invalid updates and on the last I got the final 21a error code... after that on the next Win10 boot the build 10041 started to install normally.

Preferred Solution: Windows Update Error 0xc000021a Installing Build10041

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hi, i built my PC back in august and have had no issues, until now.
I got a windows update notification

-updates
"Cumulative Update for Windows 10 for x64-based Systems"
"Update for Windows 10 for x64-based Systems (KB3106932)"

as always i reset my PC when there's a windows update and when i do it cannot access the boot drive, so i proceed to go into the command prompt and input the "DISM /image:c:\ / cleanup-image /revertpendingactions" which puts me into the Deployment Image Servicing and Management tool

i move the pending.xml and pending.old
(via the "move C:\Windows\WinSxS\pending.xml C:\Windows\WinSxS\pending.old" command) the folders and it works until i restart my PC and it brings me back to the inaccessible boot drive window and i have to move the folders again.... is there a permanent fix for this? it's really annoying and i'm totally lost

So it all started last night when i accidentally tripped on my power cord, unplugging it from tthe tower during the login screen. At first, I thought nothing of it, and I just restarted the computer. But unfortunately I was met with the BSOD with that error code. All of the online solutions I have encountered that don't involve removing all my files or using a windows 8 installation disk I have tried.
So then after the BSOD I restart and get to a screen saying automatic repair failed. I try to refresh the PC- no luck. I'm definitely not resetting my PC and losing all my files so I go into advanced options. Foolishly I have no backup USB or anything so I try a system restore. Nothing happens, same old BSOD. Then I try the various command console solutions i found in the advanced settings command prompt.All of them don't work and give me a reply saying that the image was not found or "drwtsn32.exe" was not found in the image specified or whatever. It is always prefaced with "x:\windows\system32", not C:\. I cannot start in safe mode and disabling driver signature enforcement also didn't work. Any help before i just buy a windows 8 installation disk would be greatly appreciated.

I tried different methods in this error like, refresh pc(can't refresh),system restore (can't restore), CMD - bootrec/fixboot, bootrec/scanos.....etc. and SFC/scannow(didn't work) , I tried the startup settings where you can see F1-F9, tried safe mode to disable driver signature options but it won't work, same error pops up in the startup (0xc000021a). I tried using the windows 8 installer- repair my computer option- but startup settings is not there. i can't go to safe mode. please help how to fix this error without losing my files. THANK YOU

Yesterday I successfully installed Windows 10 as per Microsoft instructions only to find today an error message stating “Error 0xc000021a Terminate yes or no”. I clicked yes thinking this was the correct course of action, but unfortunately, I have not been able to connect to Windows since.
When starting my PC a message appears stating there has been a problem and will restart in a few moments. An automatic repair screen appears followed by a screen asking “Choose your keyboard layout”. This screen is frozen and I’m unable to use the mouse or touchscreen. I can proceed no further.
My PC affected is an HP Touch smart 310

Help!
 
I reboot my PC last week as the computer seemed not responding and I ended up like this:
 
First, it was a black screen with 'autochk program not found - skipping AUTOCHECK
 
Then, the blue screen appeared, revealing the error code 0xc000021a
 
The computer automatically restarted and directed me to the automatic repair screen. Choosing restart will cause the PC to repeat the error again.
 
I tried the method stated in http://appuals.com/best-fix-steps-fix-error-0xc000021a/ but it does not work.
 
I downloaded GTA V from steam on the day before the PC crashed and I ran it. This was the only program I download recently before the PC crash
 
Please Help.

Asus S200E notebook, Win 8 Pro

I recently took in this laptop for my neighbor. The original idea was to scan and clean up the system. I set the laptop up in my office, ran an MSE full scan with no issues. Then ran a full Malwarebytes scan, which returned a few pups, which were removed.

After tending to other matters, I turned back to the laptop to find notification that there was a problem and windows had to restart. I ran another MWB scan only to have the system restart again. This time, the system tried to repair itself with automatic repair. No go. All reboots ended up back at the advanced startup options screen. No ability to restore the system image, no system restore. All I could get to was the cmd prompt.

Googling turned up all sorts of people with this issue (mostly older posts), but very few solutions.

This fix got my system booted again by removing pending update operations.

Apparently, an MS update is the source of the problem. To further reinforce this, until I turned off automatic updating, it would happen again. I also disconnected the machine from my network to revoke its internet access.

So the machine is no longer having start issues, but I'm not sure which update it is. I have 17 pending optional updates, but those haven't installed, so I doubt they're an issue.

As this is my first post, I did look for similar issues, but didn't find one.


I am by no means a computer expert, but have grown up around them, and have used them actively for the majority of my life, so I have a fair familiarity with them.

I recently completed my first PC build, and everything worked flawlessly. Windows 10 installed and ran fine, all my hardware was recognized without issue, and everything updated automatically upon startup. My goal was a strictly game-centric build, no overclocking or anything.

I come home today, and realize that my PC goes into the windows auto repair immediately, prompting me with an 0xc000021a error. My motherboard debug LCD was prompting me with b2 (short) 99 (short) a2 (long) my manual is very vague about it, but from what I have gleaned, it has to do with my peripherals, so I unplugged mouse and keyboard (supposedly 99 represents one or the other), no luck.

I initially tried to do a system reset, and it got to about 20% (both with and without saving personal files) and said that the process could not be completed, so I resorted to safe mode.I tried booting the computer in safe mode just to try to make some progress, and then upon rebooting to enter safe mode, it froze.

I have a g75vw Asus laptop which for the most part has worked fine. Late June the computer simply wouldn't boot into windows giving the error 0xc000021a next to the " " icon. This computer was originally using windows 7 but I upgraded soon after windows 8 was released in October. For about a week before the crashing, I had been using a ubuntu 12.04 live boot jump drive for learning python. It was after a linux boot that the computer crashed but I do not think the events are related. I had also installed connectify.me, a program that turns a laptops wi-fi adapter into a router which worked well for about a week before the crash. I have gone through all of the generic hoops including safe mode(s) system recovery using a usb flash drive, refresh, and the existent yet worthless self diagnosing tool. Microsoft was unable to help without a 100 dollar fee. 

Answer:Windows 8 doesn't boot. Error 0xc000021a

0xc000021a error usually means some issue with crucial system files, which could be actually caused by some bad hardware as well. I'd start with checking hard drive... Run hard drive diagnostics: http://www.bleepingcomputer.com/forums/topic28744.html/page__view__findpost__p__160520Make sure, you select tool, which is appropriate for the brand of your hard drive.Depending on the program, it'll create bootable floppy, or bootable CD.If downloaded file is of .iso type, use ImgBurn: http://www.imgburn.com/ to burn .iso file to a CD (select "Write image file to disc" option), and make the CD bootable.For Toshiba hard drives, see here: http://storage.toshiba.com/storage-services-support/warranty-support/software-utilities#diagnosticNote : If you do not know how to set your computer to boot from CD follow the steps here

Hi All..

I was reviewing my windows updates and saw two optional updates that were pending. First one was for MS office and it went through fine. Second one was some update to AMD vision control center. During that update screen flashed couple of times and went for re-start. After that I am unable to get into the system. I tried safe mode/debugging/low resolution mode etc.. But all resulted in the same blue screen with the 0xc000021a error message.

I am able to go only to command prompt. Nothing else (fortunately I am able to backup my photos by connecting external hard drive and using command prompt). I checked the SRT log file but it doesn't say any issue. All passed.

I tried refresh PC but it came back and said "There was a problem refreshing your PC. No changes made".

I tried using win ISO image bootable flash drive. It couldn't get through me in (I just tried with PC repair option when I booted with ISO image).

Is there a way I can get over it without re-installing?

Thanks in advance...

Answer:Windows 8.1 - Error 0XC000021A after optional updates

try.....
STEP 1: Enter cmd
STEP 2: Now in the Command prompt just type System Root\System32\Drwtsn32.exe -I?. This process will register the Dr.Watson as the default system debugger which has to be -> Press Enter.
STEP 3: Again type System Root\System32\Drwtsn32.exe and then in the window choose the option which are Append to existing log file, Create crash dump and Visual Notification.
STEP 4: After setting it up restart the computer by pressing F8 in the startup and select Last known good configuration.
STEP 5: Once it got booted up, again restart the system in the normal and now try to look at your optional updates to make sure not to install whatever may have broken it before.

If this does not work then you may have to reinstall.

Today, I've been racking my brain trying to figure out how to recover from a problem with winlogon.exe which caused a "Windows logon process terminated" error with codes 0xc00021a and 0xc000034.

I found this article and it helped but didn't solve the problem. I thought I was faced with having to run a repair of the Windows installation, if not re-install.

That is until I decided to scan winlogon.exe using one of the online scanning services, like Jotti or Virus Total, to see if winlogon.exe had been infected. That's when I discovered the file was MISSING from \windows\system32. A Google search on a missing winlogon.exe file turned up this thread which provided the solution I needed!!!!

Many thanks to "coderitr" for your post! Copying winlogon.exe from \windows\servicepackfiles to \windows\system32 solved the problem beautifully!

Thanks!!!!!

had one last week that was a little different and it just magically disappeared (I'm building a new computer as soon as this semester ends if this computer will last that long).

I have MOST everything backed up on an external hard drive, but when i had tried to copy the my documents folder, it kept giving me an error, and I don't remember if I copied any of it over or not. The programs are all backed up, but AFAIK any documents I had are still on there, and I'd REALLY REALLY like to make a clean sweep through the computer and get as much copied over as possible.

It's windows xp home with SP3. It started after running an AVG scan overnight and the computer went on standby during the scan. My mom tried to wake the computer up and it froze and when i rebooted it (hit the power button once and it gave me the option to shut down, restart or go to standby like it would if i had gone to the start menu and done it) it gave me a BSOD (process1_initialization_failed), and i tried again and it gave me a different BSOD (the one im posting about).

I have a recovery console.ISO on a CD that I found off of these forums and it works, but I DO NOT have the windows XP CD. It's a Dell dimension 4600 (from late 2003 hehe).

Hello, I am attempting to install a Windows Update for Service Pack 1, and cannot do so. I'm running Windows Ultimate x64 bit, and need the Service Pack to run a couple programs I cannot run without it - namely Dolphinx64 netplay.

That being beside the point, I have attempted to run the ISO file downloaded from the Microsoft website and have attempted using the online Windows Update in my system. I also tried manually upgrading my Windows 7 using a x64 Windows 7 ISO install file and selecting "upgrade", but it didn't let me because I "can't upgrade a 64-bit system to a 32-bit system" and "can't upgrade a 32-bit system to a 64-bit system". I got both of these errors at the same time - so that's a dunce.

I also used the System Update Readiness Tool found at :

Fix Windows corruption errors by using the DISM or System Update Readiness tool

and it didn't work either.

As stated in the title, the error code is 80070490. Attached is the CBS zip file asked for in the instructions for posting. I couldn't copy the CBS.log file -- and all the times I attempted to take ownership didn't work. If required, I will try again to get it. For the time being, I used an elevated command prompt to open the CBS log via notepad with a notepad command, and copied all contents into a notepad and included that with my .rar.

I also ran sfc /scannow before uploading this all, so that has been done as well.

Hi there guys!

I've noticed you have helped people before having the same issue I am. When trying to running windows updates (service pack 1) I am getting the 800B0100 error. I have tried all the "Microsoft" fixes (FixIt, SUR tool etc), but no luck. I have run the sfc /scannow and have the CBS log (although I have no idea what it all means). Can anyone help me find a fix please????

Many Thanks,

Mezworth

Please follow the Windows Update Posting Instructions and post the requested data
If the file is too large (8MB compressed), remove the older CBSPersist cab files until the final file is below the limit - you can always post them separately after zipping them. (the forum doesn't allow the upload of bare CAB files, for a number of reasons)

Hello,
new to this forum, my apologies if I've missed any of the conventions for posting. I have been dealing with a persistent error 800b0100 error when trying to update to service pack 1 for Windows 7 Professional. I've tried running Mircosoft FixIt in aggressive mode and have ran the SUR tool numerous times with no success. Attached is the CBS folder, there were 8 0x800F0900 errors as well as 8 0x00000000 errors in the system update readiness log. I'm very stuck as to what to do next, any help greatly appreciated!

Raghuvaran.

Answer:How can I fix WindowsUpdate_80240020 error while installing Windows 10 update?

Was the install prompted by you or did the little W10 reminder from the task bar tell you it is ready for the upgrade? If the former, your W10 upgrade tasker may not be ready even though your machine may actually be ready. It's stupid, I know, but I have ready this from a few folks regarding this particular error.
I get the same error when I force it from Windows Update even though the tasker still says "Thank you for reserving your free upgrade." Button = "Ok, notify me when ready." I get a completely different error code when I attempt an install from the downloadable install tool.

Update KB3023266 is failing with error 800B0100. I have tried:

- System Update Readiness tool
- sfc /scannow, which said it fixed something but I still cannot install the KB

Attached is my CheckSUR.log which shows some errors. Is anyone able to help out? Thanks!

Answer:Windows Update: Error 800B0100 on installing KB3023266

A quick check on KB2949927 which CheckSUR points to as the culprit tells me that Microsoft has pulled this update. Unfortunately this update does not show in my currently installed updates list, so I can't uninstall it - though I guess it isn't installed at all. Weird though that it's still causing issues.

I've got a problem with the Win 7 SP1 update not installing.

My OS is windows 7 Home Edition 64 bit.

The SP has been refusing to install for the best part of 2 years but hasn't really bothered me but now I have a third party program which won't install if SP1 isn't applied !

I've already run the Windows Update readiness Tool and it's identified 20 files which are corrupt/missing.

I've already run the SURT and here are the files.
The KB2633952. update will not install by itself and the log file indicates it's some of the related files which are causing the problem.

I have been trying to install updates on a new setup Lenovo Thinkcentre with Windows 7 Pro 64-bit. All updates were successful except for Internet Explorer 10 for Windows 7 for x64-based Systems. This update gives error 9C59. I have tried a number of fixes, some related to .net, as some of the error information pointed me in that direction. I have tried the Microsoft fix-it for update problems to no avail.

Again, the error code in Windows Update is 9C59.

I am attaching two CBS zipped files, as my original would not upload, and I was thinking it might have been too big, being over the 10Mb limit. The files are CBS-1.zip and CBS-2.zip. The second file (CBS-2.zip) has three of the .cab files in it, all the text files are in the first zip.

Hi! I got errors 80070BC9 and C355 when trying to install SP1, security updates KB2478661 and KB2556352 and Internet Explorer 9 with Windows Update. I use Windows 7 Professional x64. I tried to install the updates manually, used the Windows Update Readyness and FixIt tools, and to reinstall the Windows Update agent from the command line as administrator with the /wuforce option. Nothing worked. I uploaded the checksur.log. Can you fix this please?

Answer:Windows Update error when installing SP1 code 80070BC9

Magnusmaster,

* First & foremost I recommend you only do a few updates at a time.
Set Windows to notify you of updates but YOU choose which to do & when.

* Certain Security software can cause updating issues.
To find out if 3rd party software is causing the updates to fail to install > configure the system to Clean boot and then check for updates.

How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

* You could also try resetting Windows Update Components.
To do this:
1. Click on the following link: How do I reset Windows Update components?
2. Click Run in the File Download dialog box, and then follow the steps in the Fix it wizard.

* Instead of using Windows Update try the SP1 Download:

Download Details - Microsoft Download Center - Windows 7 and Windows Server 2008 R2 Service Pack 1 (KB976932)

For 32-Bit Windows 7 download: windows6.1-KB976932-X86.exe

Windows 7 x86, downloaded offline installer IE11-Windows6.1-KB2977629-x86.msu (need the last version of IE11 because older versions don't work correct with some software) getting an error, something like "not suitable for this computer" (sorry, don't know the exact translation to english). Before I also installed IE11-Windows6.1-KB2929437-x86.msu as it was told in KB article.

In the event logs i see the error because of 2149842967:

SFC /scannow shows no errors

Also there is an update which can't install and shows error 9c48
Computer in corporate network, all updates are installed with WSUS. Other computers don't have this problem, only this one.

I tried to uninstall IE11 with the command FORFILES /P %WINDIR%\servicing\Packages /M Microsoft-Windows-InternetExplorer-*11.*.mum /c "cmd /c echo Uninstalling package @fname && start /w pkgmgr /up:@fname /norestart" - after that I couldn't install it again. had to recover from the latest recovery point.

Also I installed the Windows6.1-KB947821-v34-x86 update, which should fix some problems, but it did not happen

Hi guys, 
Recently I updated my surface pro 3 to windows 10 and I was installing the windows update and restarted my tablet when I saw this error code: 0xc0000225
A blue screen appeared and it says that: Your PC/device needs to be repaired. 
The application or operating system couldn't be loaded because a required file is missing or contains errors.
File: \WINDOWS\system32\winload.efi
Error code: 0xc0000225
Press the Windows key for recovery

I tried pressing the Windows key several times, or even holding down the windows button but nothing changed on the screen at all and it is getting frustrating. 
Tried pressing Ctrl Alt Del but the tablet just restarted itself to the same blue screen again. 
Tried pressing F8 button, the screen just refreshed itself to the same page. Same thing occurs when I pressed F10 as well. 

Has anyone encountered this problem and resolved it successfully? PLEASE HELP, THANKS!

I tried uninstalling the updates with no luck.

I recently updated my PC to windows 10. It worked fine for a couple of weeks, but then it stopped booting. I started it regularly, and it showed the HP logo with the spinning circle, but then it just loaded into a flashing grey and black screen. Booting it in safe mode only got me a blue screen error, with the 0xc000021a error. I've looked pretty much everywhere, and I can't find a fix that works. Sfc scans stop at 100% verification and say "Windows resource protection could not perform the requested operation." I tried "CHKDSK C: /R, but it found no errors.

I have 3 Updates I've been trying to install for a while, however they seem to keep failing. I've never had any issues previously with Windows Update, and I keep the computer relatively clean. I've tried a few troubleshooting steps ( Such as running my Registry Cleaner, Fix-its from Microsoft )

I am getting the Error 80070643. I ran the Fix-it from the Microsoft Website - Windows Update error 80070643 and the Microsoft Office Source Engine Service is already running.
I also went here, and ran the Fix-it which resets Windows Update, In Aggressive Mode - How do I reset Windows Update components?

Ran Windows Update again, Same error.

I’m running Windows Seven x64 Home Premium, I have not made any recent changes to my computer.


Either the Updates are bugged, or there's something else going on here. I'm going to try installing them from the Administrator Account - I am going to try in Normal Mode and In Safe Mode With Networking and post back the results. If anyone has any suggestions I'd be very grateful. Thanks

I've honestly never really had an issue with Updates. This is very odd.


**I tried Windows Update on Administrator with no success. I also tried to run it in Safe Mode, but it would not open.**


I'm going out - I will be back later.

By "dead" I mean it is not doing anything.
Hi. I started my Samsung laptop today to find the entitled error. No "help" I have come across has worked, especially on microbrain's website. It says it is collecting some "error info" and has not moved from 0% since it started nearly 25 minutes ago. As soon as I saw it I knew it was a fake non-error, not doing anything, and certainly not fixing anything.
Pressing F8 is ignored by this wonderful piece of nothing, and I can't make the drive work via a USB dock using another windose OS on another drive, either.
How can I fix it?
Thanks.

Answer:'0xc000021a' dead error

I'm on mobile so I can't see the edit button.
I don't have this installation disc and I can't make a boot USB disk, either, because I can't get into it st all. It keeps on either going to the Samsung splash screen with the rotating icon then not doing anything, yo the error/error info-"collecting" screen immediately where it reboots immediately and alleges to try again, or it mentions it is "preparing automatic repair", which I don't know why it's called that because it does NOTHING automatically/by default, and does NOT repair ANYTHING.

I tried resetting my laptop, but get Error: There was a problem resetting your pc

The only way I have found to get past error 0xc000021a is to disable driver signature enforcement, but this is only a temporary solution. Every time I restart or reboot my pc it will give me the error which is really annoying. I have went through the repair my computer scans many times and every time it will say that it couldn't repair the pc. The hardware scans never find any issues as well.

I kept my computer on over night and I accidentally hit the print screen button. I have a special program called 'Greenshot' so it overlays the screen with a grid region selector and lets you drag and save. I didn't drag and save so I left it like that over night.

As soon as I woke the computer up it froze the entire screen nothing could be down. Also a message pop up about failed nvidia drivers. I decided to just force reset my computer since their was nothing I could do.

Boot it up and got all the way to the logo and loading screen. A few seconds after I BSOD with the error 0xc000021a.

Reset the computer and the auto repair screen came up. I won't let me reinstall windows w/ keeping personal files, safe mode doesn't help nor does the force drivers option, I have no idea if windows have "Boot from last known boot" or have it verity all system64 files like windows 7. Nothing work in the repair menu but the command prompt which is label X Drive instead of C drive by default.

I heard windows 10 likes to secretly update bios so I don't know it that could be the problem. Anyways I have had boot loops in the past where if I plug too many usb devices in the back IO panel the computer will just boot loop.

Ok, I clicked 'update and restart' while turning off my Surface RT, and instead of booting my OS, Windows collecte 'some error information' and restarted to a BitLocker error screen asking me for my recovery key. So, I went on the microsoft website with my phone and found the recovery key, typed it in and tapped 'Continue', but it eventually says 'Automatic Repair couldn't repair your PC'. I tap 'Advanced options' and then 'Continue:Exit and continue to Windows RT'', but I just end up at the original BitLocker error screen. If I go to 'Troubleshoot' and try 'Refresh your PC', it says 'the drive where Windows is installed is locked. Unlock the drive and try again. I tap 'Cancel' (the only option) and try 'Advanced options' then 'Automatic Repair', I get the same error screen as before, so I tap 'Startup Settings' and then 'Restart'. Eventually, I get a BitLocker screen that says ''you must enter your recovery key to access Startup Settings: to protect the privacy of your data, BitLocker has prevented the unlocking of your drive.

Hello,
I have installed Windows 8 Pro on my PC and on my Laptop. The problem is since yesterday the laptop ist showing the error 0XC000021A. It only writes that my PC ran into a problem and needs to restart. After a restart it just writes the system must be recovered and if I click on "Recover" it only shows the Win8 logo and nothing happens. I tried it several times and always get the same error.
The biggest Problem is I cant access the BIOS and change the boot device, so its not so easy to reinstall Windows. I always have to open the device and to format the hard disk on an other PC.
Is there any way to solve this problem without reinstalling Windows? I cant access the PC so all the other ways written in the internet don't work in my case.

Alright so here I go... I get home from work and boot my PC, only to find it wasn't responding to anything and the clock dissappeared from the welcome screen. So, as most other people would, I hard reset it as it would not respond to the power button.

However, I seem to have created a problem for myself... I'm now stuck in a bootloop in which the PC refuses to fix itself. I start it... I get error 0xc000021a in a bsod and it reboots to try and repair, in which that fails. I have tried a 2 separate system restores, both 28th and 23rd of January, to no avail.

Sorry that I cannot create any dump of any kind, as I can't even access any part of my PC.

I've tried other methods such as the DISM command, only to get some error stating that I'm supposed to use an /online command. Eh?
I've tried booting into safe mode, only to get the exact same error.
I cannot refresh or reboot as I do not have access to a disk or flash drive at this point (my kid sister snapped my disc in a fit of rage, irrelevant but worth noting.)

I can't even chkdsk because it says something about the HDD being locked?

Hello all, Im new here an need some help. I am trying to fix a friends Dell Dimension 8300. It was filled with tons of viruses. I got most of them, but after a restart I keep getting the BSOD error 0xC000021A followed by Cx0000034. I can't boot into any of the options when I press F8. I still get the message regardless. His CD drive doesn't work, so I cant boot from a disk. I removed the HD and put it in an enclosure and hooked it up to my computer to try and diagnose the problem from my computer. Is there anyone that can help me Can I replace files on his HD from my Windows XP Home Edition SP2 that will make it work again?? (He is running XP home SP2). I have not added any hardware or Ram. Just Windows live onecare to remove the viruses. Thanks in advance for whoever replies!

And yes, I have search all the knowledge bases and this forum and nothing has worked so far.
 

Answer:BSOD 0xC000021A Fatal Error

For anyone who has or will have the same problem. Here is what I did.

I opened up the tower for the Dell 8300 and took out the HD and the CD drive. (the CD drive didnt have the right drivers and can't find them, but it ran).

I plugged the IDE cable (master) into the CD drive and power cable.

Then I plugged the Slave end of the IDE cable into the HD.

Under settings (F2) I changed all the settings to "Auto" under the drive configuration settings. And changed the boot order to boot from the CD drive.

Then I inserted the Win XP CD into the drive, and rebooted.

Then I pressed "R" after the Win XP CD loaded all the files. The "R" is the repair Win XP installation. Everything loaded onto the HD without any data loss! The computer finally boots up now. Now I just have to put it back together LOL.

Using Windows 8.1 digital purchase, no CD.

This classic error just started happening yesterday. Had no problem with the pc in the morning, came home late and when I tried to turn it on it didnt got pass the error screen. All I remeber doing in the morning is an adobe flash update which I did not install, just dowloaded to install later. Then nothing else, I was using firefox and did nothing else.

Tried almost everything to solve it.
Every cmd command that is around.
Sfc scannow
Bcdedit into safe mode, with and without cmd, and bootmenu policy.

Pc just wont start in safe mode either.

Tried to restore to previous version, an error comes up saying it was not possible. Tried all three of the available dates.

Tried pressing F8 and starting safe mode from there and still no result.

None of the "repair" options work of course.

I can acsess the BIOS, on the gygabyte screen. Not sure what to chabge in there. Anyways, tried with "fast boot" and same error occurs.

The copy is a digital purchase, so no CD.

Any ideas? Appreciate it

Answer:Error 0xc000021A PC wont boot

Do you have any dump files under C:\Windows\Minidump ? If so, please copy them from that directory and upload them here. You should be able to copy them via command line if that's all you can access (if you're not sure how to do this, let me know and I can help) - either that, or you can burn a Linux LiveCD (such as Ubuntu or Mint), boot off of it, and use a GUI environment to copy them to an external storage device.

https://msdn.microsoft.com/en-us/lib...=vs.85%29.aspx
Try Last Known Good Config boot option.

When you ran SFC, did it find anything? Usually it will only repair stuff if you have a disc in the drive for it to reference.

Have you tried running a disk check? At the command prompt:
chkdsk c: /f /r

After it automatically restart it says

After multiple tries, the operating system on your pc failed to start, so it needs to be repaired
Error code: 0xc0000001
You'll need to use the recovery tools on your installation media. If you don't have an installation media (like a disc or USB devices), contact your system administrator or PC manufacturer.

This morning, I needed to check my emails so tried booting up my laptop only for the BSOD saying "Your PC ran into a problem and needs to restart. We are just collecting some error info and then we will restart for you." I allow it to reach 100% but whenever it starts to restart my laptop just freezes. No matter how many times I boot my computer this always seem to happen which is why I am unable to follow the BSOD posting instructions. Is there anyway I can fix this as I need certain data that is on my hard drive?

I went to use my computer this afternoon and it locked up and now I get "error 0X000021A" I have been unable to get it to boot into safe mode or anything else. It has an SSD and I have the original HD which I installed and the computer will boot to that. However it has windows 8 as the operating system. I had done the upgrades to 8.1 and 10 but they are not on the HD? Is there any way to get the windows 10 loaded again? If not, I will continue to get by with Windows 8. I can't get the log information because it won't boot up.

Hi

I upgraded from Windows 7 to Windows 10 and it was working fine for a few days but now I get BSOD with error code 0xc000021a everytime I boot it. I've tried the following 'fixes':

System restore --- Runs for a few minutes and then says "Could not restore your computer. No changes were made"

Clicking on any of the advanced startup options --- BSOD

Reinstalling windows 10 with a usb --- Results in it going into circles with this message "The computer started using the Windows installation media. Remove the installation medial and restart your computer so that Windows starts normally. Then, insert the installation media and restart the upgrade. [Do not select iCustom [advanced]I to perform an upgrade. iCustom [advanced]I installs a new copy of Windows and deletes your programs and settings.)"

I've taken the usb out and restarted the computer several times, even called Microsoft Technical Support. They had no idea what to do.

I used to be able to access the command prompt and I tried everything suggested in this article here https://neosmart.net/wiki/0xc000021a/. The reason I say "used to" is because things recently got alot worse when I changed the boot order and now it just turns black after the bios screen.

Download and install ThinkVantage system update utility from Lenovo support site, and run the application to update all the latest drivers and application for your system.
Run system scan from Lenovo solution center.
Please go to my computer ? C drive ? Windows ? System32 ? copy Minidump folder to desktop with compressed format, upload it to any 3 rd party cloud drive and provide us the link, so that we can verify the error file and assist you further.

I have a bootable USB with Windows 10, and another hard-drive plugged in running Windows 7. I have used the W7 boot to save my personal files which is lucky.

What I have tried:
- Boot to safe mode, disable driver signature
- Bootable USB -> "sfc /scannow /offbootdir=c:\ /offwindir=g:\windows" returns "Microsoft Resource Protection could not perform the requested operation"
- Registry replaced with backups

The SSD seems 'healthy'. Screenshot. CHKDSK passed but "failed to transfer log messages status 50". Are there logs I can locate manually on the troublesome drive and upload?

Any help would be appreciated, let me know if I can provide more information.

How much free space does each partition have? Not enough can cause quite some issues, at least 10-15% free space is recommended.

Hello again!

I'm fixing a computer for a friend of mine. The computer at issue is running Windows XP, and suffers from the apparently not-so-uncommon STOP: 0XC000021a error with WINLOGON.exe. The computer was infected with a virus that caused the problem, NOT a hardware or new software installation.

I've spent hours researching a solution to the problem with no avail. Most guides reccommend reverting to the "Last Known Good Configuration". I tried this first, and it didn't work. He also has no Windows restore points to use.

The second common solution is to use a Windows XP CD to do a repair installation. As luck would have it, he doesn't have his Windows XP CD. I don't have one, either, since I've been using Vista for a while.

I've definitely isolated the problem to WINLOGON.exe, using DrWatson. I CAN boot the computer into Safe Mode, but I cannot boot it normally. The restart and BSOD occur roughly 1-2 minutes after the XP login screen appears.

Any tips or ideas?
 

Answer:Virus caused STOP: 0XC000021a error in XP

I'd also like to note that I've used AVG anti-virus and Spybot on the computer in Safe Mode, as well as Malware Bytes. I believe that the initial virus is gone, but I can't be sure until the problem is fully resolved.

I bought my yoga 2 13 in November 2014. It has worked well till last week. Now it freezes for 10-20 seconds on the simplest click to another window. I got an error xode 0xc00021a.

Hi rajeshprasad1 , 
 
 
Welcome to the Community Forums.
 
Error 0xc000021a  may be a system file error on base check but may also hide underlying issue  like bad sectors or drive. On other scenarios , this error can cause system not to boot to Windows .
 
Best that you take time to back up everything that is important or if that would be hard, try to get data recovery tech / center to slave the harddrive for the back up if possible and have then run a harddrive diagnostics at the same time. 
 
Would it work ok on safe mode?  
Would you be able to run individual Storage test using this link .
 
Update us how it goes .

Answer:0xc000021a BSOD Error (Not login related) Win8

I threw the dump into the debugger, and it tells me, "Windows must now restart because the Remote Procedure Call (RPC) service terminated unexpectedly." This is bad for you because it means your dump doesn't have enough information to explain RPC's crash. Given the age and popularity of Win8, I'd suspect some third party driver / service is mucking things up. It could be the copy protection (SafeDisc) some game installed.Try updating drivers (your sound driver was released a year before your OS) and / or uninstalling customized drivers (the Razer stuff).How To Ask Questions The Smart Way

Hi everyone,

My friend just began getting a fatal system error when he tries turning his computer on. It loads up all and displays the background, and then crashes. The error is a blue screen:

STOP: C0000021a {Fatal System Error}
The Windows Logon Process System process terminated unexpectedly with a status of 0xc0000005 (0x00000000 0x00000000).
The system has been shut down.

I've been unable to find anything to correct this problem. It can boot up into safe mode but not safe mode with networking capabilities (it then does the same thing). Anyone know of any solutions? Thanks!

Where do I even start?
A client of mine came to me with their HP desktop and were saying it could not boot and restore points were not even working. I thought I would have this worked out in no time. I was wrong.

Here is the details for everything:
- Error code is 0X000021a and I can only see it when I, attempt to, boot into Safe Mode (Which all Safe Mode options do not work.)
- Normal booting into the OS results in a mainly blue screen with thin lines and streaks cutting through the screen and nothing is distinguishable.
- I tried System Restore and there is nothing there to access, says Windows.
In this next section, I run commands from the Command Prompt in the Windows Troubleshooting section of the boot.
- SFC scans result in this now: "Windows Resource Protection could not perform the requested operation."
- Chkdsk: Regular Read-Only mode tells me "No further Action is required" and running the extended commands, such as /f /r, takes a huge amount of time and I only did that once. No dice.
- DISM commands seem like such a good idea but I can run only one of them and it does not help me in any way. Say I run "DISM /Online /Cleanup-Image /CheckHealth" it gives me "Deployment Image Servicing and Management Tool. Version 10.0.14393.0.
Error: 50. DISM does not support servicing Windows PE with the /Online option."
And if I try any other DISM commands, more errors, like Error 2.

Hello all,

I was asked to disinfect a friend's computer that was absolutely infested with virii, malware, spyware, and the like. I began by installing and running AVGh antivirus. After running a full scan, I was asked how I wanted to proceed regarding a particular infected file (unfortunately I did not write down the filename) and I choose either delete/qyuantine. Immediately
following, I was greeted with a blue screen that read 0xC000021A error. Since then, I have tried every possible way to boot: Safe Mode, Last previous configuration, etc. I also tried booting from the Dell utility partitiion and all those tests Passed (even the OS/Boot up test- go figure). Because all of these boots were unsuccessful, I decided the only way to fix this would be a fresh format. Well I can't even do that! I choose boot from CD and still get the blue screen with the same error! How in the world can I fix this if I can't even format and reinstall the OS? Any ideas?

I have googled endlessly and failed to come up with a solution. I read Microsoft's documentation but there is no way for me to follow the steps since I cannot access any kind of prompt.

Thanks so much in advance.
