Windows 11 Error code: 0xc0000001

[Manon71]

Hello, I purchased an HP All-in-One PC on October 6, 2025  and it
“It displays error 0xc0000001 and will not start.”
“I have already performed all diagnostics and software repair attempts (HP hardware tests successful, F1/F8/safe mode access impossible), without success.”
“Since the device is new and unusable, I would like to claim the warranty for repair or replacement.”

1. Initial Description of the Failure

Initial symptom (yesterday): Upon startup, the computer requested a BitLocker recovery key. I successfully entered the key.
Result: The computer then entered an infinite restart loop (displaying the HP logo, then a black screen, then the HP logo, and so on).

2. Current Symptom (Today)

The computer no longer starts up and systematically displays the same blue screen in a loop:

RECOVERY: Your PC couldn't start properly. 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 recovery tools. If you don't have any installation media (like a disc or USB device), contact your PC administrator or PC/device manufacturer.
Press Enter to try again; Press F1 to enter Recovery Environment; Press F8 for Startup Settings; Press Esc for UEFI Firmware Settings."

Access to the Windows Recovery Environment (WinRE) is impossible.

3. Actions and Tests Already Performed (All Unsuccessful)
I followed step-by-step troubleshooting guides. Here is what I tried:

Hardware Diagnostics (via the HP BIOS built-in tool):
I ran quick hardware tests (RAM and Hard Drive/SSD).
Result: All tests were successful (“SUCCESS”). The hardware appears to be functional according to the HP diagnostic tool.
Attempts to Access and Use Recovery Tools (WinRE):
I tried to force access to the recovery environment by abruptly shutting down the PC three times in a row during startup.
Result: This method failed. Instead of reaching the “Troubleshoot / Advanced Options” screen, the computer returned directly and repeatedly to the 0xc0000001 error screen.
As a result, I was unable to use the following tools:
System Restore Tool (Automatic Repair)
System Restore
Uninstall Updates
Command Prompt to run chkdsk, sfc, bootrec
Access to Safe Mode (Options 4/5/6 in Startup Settings)

Conclusion:
The PC is new, the quick hardware diagnostics are fine, but all attempts to repair the software using the built-in Windows tools have failed because I cannot access them (including the USB key). The computer is completely unusable. I am requesting warranty coverage.

Thank you in advance for your help.

There are some problem with Bitlocker and certain versions of windows as explained here

You may want to just do a cloud restore and start over.

HP is removing cloud recovery for system over 5 years old.
The actual wording is a limited time after the warranty expires
You may want to get a copy of the cloud recovery before it is too late.
Cloud recovery provides all the custom HP drivers.
Go to the below site and enter your product ID including the 3 characters after the # character
If you have cloud recovery you can restore your system using a 32gb flash.
It may take an hour or more to create the recovery USB.

hello, thank you for your message,

My PC is new; I bought it last month. The problem is that it is completely frozen, and I cannot access the cloud or USB drive. When I turn on the PC, I only get a blue screen with error 0xc0000001 and the accompanying message. When I try to press F11, F9, F2, etc., nothing works, and it always returns to the error message. I wanted to know if there are any other solutions to unblock Windows? Otherwise, I will have to contact HP support tomorrow, but in that case I will have to return the PC, which will take a long time and I won't have a PC in the meantime. That's why I would appreciate it if you could help me with a solution other than the cloud or USB key, since I can't access the PC's controls.

Thank you for your help.

Unless I'm mistaken that error code is associated with Windows. Can you get into the BIOS setup?

If the F10 key does not work when powering up then return the PC.  Depending on how fast your PC is, you may have to quickly press the escape or the F10 key repeatedly before the computer realizes you want to enter the setup mode.  Press ESC, DEL or F10 no faster than once per second after powering up.

If you can get into the BIOS setup, then press the key that sets the default.  Ensure that secure boot is enabled and save setting.

Cloud restore is done using another computer and you must have admin rights.  A library PC cannot be used to create the cloud recovery USB.

Unfortunately, I cannot access F10. Tomorrow, I will contact HP support. Thank you for trying to help me. I will keep you posted on what happens next. Have a good evening.

Hi BeemerBiker,

J'ai utilisé le kit USB HP Cloud Tool une fois avec l'aide d'un technicien du support HP. J'ai pu me connecter à Windows. Tout fonctionnait bien, mais lorsque j'ai installé les mises à jour demandées et redémarré le PC, le problème est réapparu et tout s'est à nouveau bloqué. Comme je suis sous garantie, je vais apporter le PC en réparation demain. Merci pour tout. Vos conseils m'ont été très utiles, car j'ai donné au technicien la réponse pour effectuer d'abord cette réinitialisation à l'aide du kit HP Cloud Tool. Mais le problème, c'est que mon PC a probablement un défaut de fabrication, ce qui explique pourquoi il présente des bugs comme celui-ci à chaque nouvelle mise à jour. Je préfère que le support HP le répare tant que je suis encore sous garantie et que le PC n'a qu'un mois. Passez une bonne soirée et merci encore.

I used the HP Cloud Tool USB kit once with the HP support technician. I was able to log into Windows. Everything was fine, but when I installed the requested updates and restarted the PC, the problem returned to where it started, and everything was blocked again. Since I'm under warranty, I'm going to take the PC in for repair tomorrow. Thank you for everything. Your advice was very helpful to me, as I gave the technician the answer to first perform this reset using the HP Cloud Tool kit. But the thing is, my PC probably has a manufacturing defect, which is why it has bugs like this with every new update. I would prefer that HP support repair it while I still have the warranty and the PC is only 1 month old. Have a good evening and thank you again.
