Green screen Inaccessible_boot_device

Hello,

 

I have a problem with my computer since I launched a update yesterday evening I can not start my computer again.

 

When I’m starting it I have a green screen saying that my computer with windows insider did not start well and it will restart. The stop code is « INACCESSIBLE_BOOT_DEVICE ».

 

Then it restarts and show a blue screen with for the title I have « Recovery » (« recuperation » in French) with 3 options (code error : 0xc0000001)

Enter to try again

Esc to launch the recovery

F8 to go to other 10 options (start in safe mode with command prompt for example)

but each option gives the same thing a freezing black screen with the brand of the computer and sometimes one « please wait » depending which option I choose 

 

before that I had problems but I asked ChatGPT to help me and it did not help but I don’t have the same option as before. ( before I could do advanced settings and launch the comand prompt but now I’m not even able to access the command prompt even when I chose «  safe mode with comand prompt »)

 

can you help me please ?

 

kind regards 

 

Tom

    I solved my problem with Chatgpt 
    Here are the instructions you have to follow :

    Here is the full English translation of your guide:

    Guide: Fix INACCESSIBLE_BOOT_DEVICE and Windows Update Errors on Windows 11 Insider Preview

    Symptoms Encountered:

    • On startup: Green screen with the error code "INACCESSIBLE_BOOT_DEVICE".
    • The PC redirects to the "Recovery" blue screen.
    • Unable to access certain applications like Chrome or Firefox after restarting.
    • Windows Update displays errors:
      • 0x800711c7 and 0x80246007.

    Steps to Resolve the Problem

    1. Disable Secure Boot in BIOS/UEFI

    • Restart the PC and access the BIOS/UEFI (usually via F2, Del, or Esc during startup).
    • In the Boot or Security settings, disable Secure Boot.
    • Restart the PC. This temporarily bypasses boot issues.

    2. Repair the EFI Bootloader with Diskpart and BCDboot

    Access the Command Prompt

    From the blue Recovery screen:

    • Go to Advanced Options > Command Prompt.

    Option A: Quick Repair of the EFI Partition

    1. Launch Diskpart and identify the EFI partition:
      diskpart  
      list disk  
      sel disk 0       (replace 0 with your main disk number if different)  
      list vol   
      • Locate the EFI partition (marked as "System", formatted as FAT32).
    2. Assign a temporary drive letter to the EFI partition:
      sel vol X      (replace X with the EFI partition number)  
      assign letter=Z:  
      exit 
    3. Rewrite the UEFI boot files:
      bcdboot C:\Windows /s Z: /f UEFI
      • C: is the drive where Windows is installed.
      • Z: is the temporary drive letter for the EFI partition.

    Option B: Delete and Recreate the EFI Partition (if Option A fails)

    ⚠️ Warning: This method deletes the EFI partition and recreates it. It will not erase your personal data, but follow each step carefully.

    1. Launch Diskpart and delete the EFI partition:
      diskpart  
      list disk  
      sel disk 0      (replace 0 with your main disk number)  
      list part  
      sel part X      (replace X with the EFI partition number)  
      delete part override
    2. Create a new EFI partition:
      create part efi  
      format quick fs=fat32  
      assign letter=Z:  
      exit  
    3. Rewrite the boot files to the new EFI partition:
      bcdboot C:\Windows /s Z: /f UEFI

    3. Reactivate Secure Boot

    Once the PC boots correctly:

    1. Return to the BIOS/UEFI.
    2. Enable Secure Boot.
    3. Ensure that UEFI mode is activated (disable Legacy/CSM).
    4. Restart the PC.

    4. Check and Repair System Files

    From Windows, open the Command Prompt as Administrator and run:

    sfc /scannow  

    This repairs any corrupted system files.

    5. Check Windows Update

    • Go to Settings > Windows Update.
    • Click on Check for updates and install everything available.

    Conclusion

    By following these steps:

    • Your PC should boot correctly.
    • Secure Boot can be reactivated.
    • Applications like Google Chrome and Firefox will work again.
    • Windows Update errors (0x800711c7, 0x80246007) will be resolved.
