Windows 10: BSOD on Boot 0xc0000034

Heyo,

I'm having some BSOD's on boot for some reason. I am unfortunately unable to post a debug report as I can't get to my desktop. However, I do have a small bit of background for the issue. I recently got an SSD, and cloned my main drive with Windows 10 over to my SSD. After that I completely wiped and reformated my old drive via command prompt, but it is still installed. It worked fine and I ran it for about 30 hours straight, installed some programs and games and played them without issue. When I finally shut the computer down, this BSOD error code came up on boot. I have tried a couple of things:

-Create Win 10 boot media and run startup repair. Bring up a screen which says "Startup Repair couldn't repair your PC. Press 'Advanced options' to try other options to repair your PC or 'shut down'to turn off your PC. Log file:" (no log file listed)

-Run system restore. Brings up a dialogue box that says "to use system restore, you must specify which Windows installation to restore. Restart this computer, select an operating system, and the select system restore"

-Use command prompt to run Bootrec /fixMBR, bootrec /fixBoot, bootrec /rebuildBCD

None of these steps have worked. I could reinstall Win 10, but the whole purpose of cloning my drive to my SSD was to save data and settings. I have my personal files backed up but I'd rather not have to reset all of my settings. Is there something else I can try first? I will be doing further troubleshooting and editing in those steps as I wait for replies.

Edit: Just tried these steps to no avail
1. Press Shift + F10 when you are at the Install Windows screen, The elevated command prompt at boot will now open.
2. Type DISKPART command
3. Enter Command LIST VOLUME, note volume no...
4. Enter Command SELECT VOLUME "no" (eg1,2,3) mine was 3
5. Enter Command ASSIGN LETTER=Z and EXIT
6. Enter Command BCDBoot c:\Windows /s z: /f: UEFI
7. Exit and restart.

Edit 2: Attempted to reset PC, bringing up a screen that says "The drive where Windows is installed is locked. Unlock the drive and try again." Resetting seemed to work as it said "getting things ready" when I clicked it. I hard shut-down when that came up because I'd prefer not to lose everything.

Edit 3: Followed the steps found here: Windows 8, - Page 3. Though I followed the instructions to the letter, when I entered the command bcdboot d:\windows, I got the error message "Failure when attempting to copy boot files." I am 100% sure I selected the right disk as all of the others are named and far larger than my 500gb SSD

Edit 4: Tried using the command "bcdboot d:\windows /s d: /l en-us," which resulted in cmd saying "boot files successfully created." No change on reboot *Mad

Edit 5: Final edit and solution!
After delving deep into countless forums, I found this post in the microsoft forums which fixed my issue. Though it is addressing Win 8, it worked like a charm for 10. Hopefully this post will give Win 10 users a somewhat comprehensive list of things to try for error 0xc0000034

"Hi,

I have experienced the same trouble as you had and I also would like to avoid
re-installing windows. So I tried to search informations for fix this problem
and I got it.

Apparentry, why we could not fix the problem by typing bootrec /rebuildbcd is
because we have confused our environment about system, more succinctly, whether
you use legacy BIOS/MBR system or newer UEFI/GPT system.

Current manufacturer shipping there Windows8 PC product as UEFI/GPT system, or if you had
installed your windows8 on UEFI/GPT, once corrupted your PC, you should fix
it in another way from BIOS/MBR system.

If you could not boot your UEFI system, (this means also you could not fix it
by windows' Automatic Repair) you could fix it by these method.

*Here to assume that disk 0 is a booting device.

a) After you boot your computer using Windows 8 DVD or System Repair Disc, a black screen
appears with gray text "Press any key to boot from CD or DVD". Press any key.
b) Select the correct time and Keyboard type.
c) Click Repair your computer in the lower left corner.
d) Select Troubleshoot from Choose an option screen.
e) Click Advanced options in Troubleshoot screen.
f) Click on Command Prompt.
g) Type these following commands and hit enter after each line of command:
"#" is an instruction comment so not to type it ;-)

# to execute diskpart program
diskpart
DISKPART> list disk
DISKPART> select disk 0
DISKPART> list volume
# find your system partition with fat32 file system. Here to assume it as volume 2.
DISKPART> select volume 2
# To assign drive letter.
# If you want to remove drive letter, use remove command.
DISKPART> assign letter=b:
# To terminate diskpart command.
DISKPART> exit

# Now, you sould move to b:\EFI\Microsoft\Boot\, as windows stores BCD in this folder.
cd /d b:\EFI\Microsoft\Boot\
# this is not necessary.
ren BCD BCD.bak
# To write a new bootsector on your system partition.
bootrec /fixboot
# If your windows running, you should do from here.
# To create BCD store. "/f ALL" is to update BIOS setting including UEFI firmware/NVRAM.
# Replace "ja-JP" with your language or remove "/l" option if you use English, of course.
# It might be sense only typing "bcdboot c:\Windows".
bcdboot c:\Windows /l ja-JP /s b: /f ALL

That's that. Booting information of your PC has been written over.

Let's reboot and see whether it go fine or not!"

A couple things to note. First, when using command select disk, this is referring to your Windows 10 boot/repair media located in your CD or USB drive. Second, at the final step I was a little confused by the wording when addressing the language. The command I used was bcdboot c:\Windows /l en-US /s b: /f All. That's about it! I was just about ready to wipe everything out and do a fresh install, so I'm incredibly glad I found this post. I hope it's able to help someone!

Help!!! Windows 10 cannot boot/reboot unless with USB inserted

Hi Sachin, just tried to do a system restore and it shows:

Recovery

Your PC/Device needs to be repaired

An unexpected error has occurred.

Error code: 0xc0000034

You'll need to use recovery tools. If you don't have any installation media (like a disc or USB device), contact your PC administrator or PC/Device manufacturer.

I searched online and found: BSOD on Boot 0xc0000034 Solved - Windows 10 Forums

I followed the steps inside and did the final step of: bcdboot c:\Windows /l en-US /s b: /f

But it does not seem to work and now whenever I try to boot from my USB it no longer comes up with the installation screen and instead goes directly to the log in screen. Whenever I enter my password for my Windows account to log in the system just says:
"Preparing Windows" and it does not change until the screen goes to black.

 

Rolled Back to Win 7 after Win 10 upgrade proves they aint quite got it right....

Thanks for reply , but when selecting Safe mode with networking, the system runs through all normal display expected in safe mode pauses as though to boot into safe mode then BSOD same error , and loops back round to error recovery screen . managed to
freeze frame BSOD on video ...Usual A problem has been detected, check for viruses etc blurb...... Technical information though is *** STOP: 0x0000007B (0x80786B58, 0xC0000034, Ox00000000, 0x00000000) don't know if this is of any help ?

Sounds like a good solution, if it would just let me boot into safe mode

 

Hi Dmdordan & Welcome to the forums ^_^,

Sorry for the delayed response. Do you still need help with this? In case you do want help, please respond to this topic and I would be notified via email and you should expect a response from me in 48 hours.

Hey Pranav,

Thank you for your reply. I think I have it all figured out. Solved this issue but ended up getting a new one. Did a clean install of Win 10 for that and everything is working perfectly now.

Thanks,
Derek

 

Alright. Thanks for letting us know ^_^

In case of any other problem, feel free to post back.

Thanks so much for this! I was also stuck with the BSOD, and simply could not boot back into Win10 no matter what I tried. Using your technique above, I am now able to get back into Windows, however... I think I may have made a slight mistake following the directions. If I pull out my USB stick, Windows says it needs to shut down. Likewise, if I don't have the USB stick plugged in, it will not boot into Windows.

Any idea what I did wrong in the above instructions?

 

Hey,

Unfortunately this was just my long process of troubleshooting so I'm far from a Windows expert. I think you would be better served by posting a new thread to this forum and linking to this thread to show what steps you took. Good luck!

 

Dear Sir, You are a king among men! Thank you so much for providing this solution! You just essentially saved me $250 and complete wipe of all my data (what the local chain store computer repair guy was suggesting) / or a 10 day wait to have this "fixed" under the warranty. Thank you so much again!

 

What he said. Wish I would have found this post using my phone 3 months ago, but it saved me tonight. You are a God to me tonight. ZOMG ty, I don't have to reinstall Win10 all the way from a fresh 8.1 reformat. TYTYTY

 

Hi there

I was wondering if someone please please assist me - I have the same issue getting a Blue Recovery screen after a recent windows 10 update - I've tried everything. I don't want a clean install as I have files I need.

Anyways I'm not exactly a tech expert so I'm quite apprehensive about entering commands. In the solution you posted that worked for you I got to through the diskpart instructions but I don't really understand the the second half, seems a little unclear. Would someone be able to clarify this? I really don't want to mess my PC up anymore by typing in the wrong command. Also, the bootable usb should it be fat32 or NTFS?

I would deeply appreciate your help with this awful frustrating issue - a million thank yous in advance *Biggrin

Im having a little problem, i followed the instructions and the "regular" start up did not work, it just send me to the same screen with the error code. but then i restarted the pc to enter the usb so i would be able to check what i did wrong and to my surprise, the pc went into windows!!!

Ok, so the problem is that the pc is starting "properly" only if i boot the system with the usb were the Win 10 boot media is installed, if i take the usb out, the system will not boot. Also if i log in to my windows 10 and take the usb while using the pc, the system freezes and i have to restart.

Can someone help me with this, i will really apreciate it.

 

Me and you together bro, im going thru the same situation. Can someone help with this please?

 

I had the same exact thing. I got it to work!! I've followed this guide and it worked! FIX: An operating system wasn't found on Windows 10 or Windows 8.1 (Solved) - wintips.org - Windows Tips & How-tos

The reason why you have to have the usb is because the boot files are on the usb.

So, the command should be: bcdboot c:\Windows /l en-us /s c: /f ALL

Noticed the same letter used in the command? I had the exact same symptoms as both of you and I just booted into Windows like normally now!

 

Hi fenix,
I think I have the exact same problem: the brilliant solution documented above got me from not being able to boot my Windows 10 world yesterday to now again being able to always boot my Windows 10 (with everything as it should be as if booting and starting up just as it did before the problem began), BUT it will only do so if my System Recovery USB stick is in the USB drive. Were you able to solve this (i.e. get it so that the USB stick is no longer necessary)? I even thought that perhaps running Startup Repair from the System Recovery stick would maybe take care of the problem, but I can no longer convince System Recovery to get me to the troubleshooting screen to try that... instead it simply boots my computer and let's me get to my normal workspace.
