Fix Error 0xc0000098 in Windows 11

Error code 0xc0000098 appears when Windows 11 cannot locate or read essential Boot Configuration Data (BCD) files needed to start the operating system. This issue typically results in a blue screen with messages referencing missing or corrupt files such as \BCD, winload.efi, or \windows\system32\config\system. Systems may fail to boot, become stuck in repair loops, or be unable to access recovery tools. Several factors can cause this error, including failed updates, disk errors, incorrect BIOS/UEFI settings, or problems creating installation media. The following methods address the root causes and help restore normal boot functionality.

Startup Repair Using Windows Recovery Environment

Insert a Windows 11 installation USB or recovery drive into your computer. Power on the device and immediately press the key (commonly F12, F2, Esc, or Del) to access the boot menu, then select the USB drive as the boot device.

On the Windows Setup screen, choose your language preferences and click Next. Select Repair your computer at the bottom left, not Install now.

In the recovery options menu, select Troubleshoot, then Advanced options, and click Startup Repair. Windows will scan for and attempt to fix startup problems, including issues with the BCD.

Startup Repair diagnoses and repairs boot file corruption automatically. If the repair is successful, Windows will restart and boot normally.

Rebuild Boot Configuration Data (BCD) Using Command Prompt

If Startup Repair does not resolve the issue, you can manually rebuild the BCD. This process is effective when the BCD file is missing, corrupted, or contains incorrect entries.

Boot from your Windows 11 installation USB or recovery drive. On the initial setup screen, choose Repair your computer, then navigate to Troubleshoot > Advanced options > Command Prompt.

In the Command Prompt window, enter the following commands one by one, pressing Enter after each:

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

These commands repair the Master Boot Record (MBR), fix the boot sector, scan for installed Windows systems, and rebuild the BCD. If prompted to add installations to the boot list, type Y and press Enter.

After completing these steps, close Command Prompt and restart your PC. If the error persists, proceed to the next method.

Check Disk and Repair File System Errors

Disk errors or bad sectors can prevent Windows from reading boot data. Running a disk check can identify and repair these problems.

Open Command Prompt from the Windows Recovery Environment as described above.

Enter the command below to scan and fix errors on your system drive (usually C:):

chkdsk c: /f

The /f switch instructs Windows to fix any detected file system errors. Allow the process to complete, then restart the computer.

Run System File Checker (SFC) Offline

Corrupted or missing system files can also trigger error 0xc0000098. The System File Checker utility scans and restores these files.

Access Command Prompt from the recovery environment.

Type the following command and press Enter:

sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

This command scans the specified Windows directory for missing or corrupted files and replaces them with correct versions. Adjust the drive letter if your Windows installation is not on C:.

System Restore to a Previous Working State

If you created restore points before the issue occurred, restoring your system can revert changes that caused boot failures.

In the Windows Recovery Environment, go to Troubleshoot > Advanced options > System Restore.

Follow the on-screen instructions to select a restore point from before the error appeared. The system will restart and attempt to restore settings and files to that date.

This process does not affect personal files but will remove apps and drivers installed after the restore point was created.

Reset This PC While Keeping Files

Resetting Windows reinstalls the operating system while optionally preserving your personal files. This method is useful if previous repairs have failed, and you want to avoid a full clean install.

In the recovery environment, select Troubleshoot > Reset this PC.

Choose Keep my files to retain personal documents and media, or Remove everything for a completely fresh installation. Follow the prompts to complete the reset process.

Resetting Windows removes installed applications and system settings but can resolve persistent boot errors.

Clean Install of Windows 11

If all repair attempts fail and your system remains unbootable, performing a clean installation of Windows 11 is a reliable solution. This erases all data on the Windows drive, so back up important files beforehand using a bootable Linux USB or by connecting the drive to another computer.

Create a new Windows 11 installation USB using the official Media Creation Tool from Microsoft on a working computer.

Boot from the USB drive on your affected computer. On the setup screen, select Install now, and follow the prompts. When asked, choose Custom: Install Windows only (advanced) to perform a clean installation. Delete old Windows partitions if necessary, then select the unallocated space to install Windows 11.

This process guarantees a fresh system free of previous configuration errors or corrupt files.

Additional Troubleshooting Tips

Verify BIOS/UEFI boot order to ensure the correct drive is set as the primary boot device.
Disconnect unnecessary drives (such as external HDDs or secondary internal disks) to avoid BCD confusion.
When creating installation media, use a reliable USB drive and official ISO files to prevent corruption.
If your system uses RAID or NVMe drives, ensure appropriate drivers are loaded during installation or repair.
For persistent hardware detection issues, check drive connections and update firmware if possible.

Addressing error 0xc0000098 in Windows 11 involves targeted repairs to boot data, file systems, and system files. Each method above targets a specific cause, allowing you to restore normal startup without unnecessary data loss.

Resolving error 0xc0000098 restores your ability to boot Windows 11 reliably and avoids repeated blue screen interruptions. Regular backups and careful update management can help prevent future boot issues.
