The error code 0xc00000d accompanied by the message “PC needs repair” can be frustrating. It usually appears when Windows 11 fails to boot properly. This error indicates that your system has encountered a problem with critical boot files or configuration.

Fortunately, there are several ways to fix this issue. Some methods are simple and don’t require advanced knowledge, while others may need more steps. Following a step-by-step approach will help you get your PC back to normal.

This guide will walk you through all the necessary solutions, starting from the easiest to the more technical fixes. You don’t need to be an expert to follow along.

Let’s begin by understanding what you should check before diving into repairs.

Quick Note Before You Start

Make sure your PC is fully powered off, then turned on again. Sometimes, a simple restart fixes temporary errors.
Check any external devices like USB drives or external hard disks. Disconnect them during troubleshooting to avoid conflicts.
Have a Windows 11 installation USB or DVD ready. This will be essential for some of the steps below.
Ensure you have access to another working computer to create the installation media if needed.

Step 1: Perform a Simple Restart

Often, errors like 0xc00000d can be caused by temporary glitches. Before moving to complex solutions, try restarting your PC again.

How to restart:

Press and hold the power button on your PC until it turns off completely.
Wait about 10 seconds.
Press the power button again to turn it back on.

This simple action clears temporary system errors and may allow Windows to boot normally.

Step 2: Disconnect External Devices

External devices such as USB drives, printers, or external hard drives can sometimes interfere with the boot process. To rule this out:

Turn off your PC completely.
Remove all external devices connected to your computer.
Turn on your PC and check if the error persists.

If your PC boots successfully, connect the devices one by one to identify the culprit.

Step 3: Use Automatic Startup Repair

Windows 11 includes a built-in tool called Startup Repair that can fix common boot problems automatically.

How to access Startup Repair:

If your PC shows the error screen, press and hold the power button to force shutdown.
Turn it on again and force shutdown once more when the error appears.
Repeat this 2-3 times. Windows will detect the repeated failed startups and automatically boot into Recovery Environment.
In the recovery screen, select Troubleshoot > Advanced options > Startup Repair.
Choose your Windows 11 installation when prompted.
Wait while Startup Repair scans and attempts to fix your PC.

This tool fixes corrupted boot files and other common issues without requiring manual commands.

Step 4: Run Bootrec Commands Using Command Prompt

If automatic repair doesn’t fix the problem, you can manually repair boot files using Command Prompt.

How to open Command Prompt in Recovery Environment:

Boot into the Recovery Environment using the steps described in Step 3.
Choose Troubleshoot > Advanced options > Command Prompt.

Run the following commands one by one, pressing Enter after each:

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

These commands do the following:

/fixmbr repairs the Master Boot Record.
/fixboot writes a new boot sector.
/scanos scans for Windows installations.
/rebuildbcd rebuilds the Boot Configuration Data store.

After completing these commands, type exit and press Enter, then restart your PC.

Step 5: Check and Repair Disk Errors

Sometimes corrupted files on the hard drive can cause boot errors. Using the chkdsk tool can help fix disk-related issues.

Run disk check from Command Prompt:

Boot into the Recovery Environment and open Command Prompt as before.
Type the following command and press Enter:

chkdsk C: /f /r

Note: Replace C: with the drive letter where Windows is installed if it’s different.

The parameters mean:

/f fixes errors on the disk.
/r locates bad sectors and recovers readable information.

This process can take some time depending on your disk size and errors found. Once done, restart your PC.

Step 6: Repair System Files Using SFC and DISM

Corrupted system files can also cause boot problems. System File Checker (SFC) and Deployment Image Servicing and Management (DISM) are tools to repair these files.

Steps to run SFC and DISM:

Open Command Prompt from the Recovery Environment.
Type and run this command:

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

This scans and repairs system files offline. Replace C: if your Windows drive letter is different.

After SFC completes, run these DISM commands one by one:

Dism /Image:C: /Cleanup-Image /RestoreHealth

These commands check and repair Windows image issues that can affect booting.

When done, restart your PC and check if the error is resolved.

Step 7: Use System Restore to Undo Recent Changes

If you recently installed updates or software before the error appeared, restoring your system to an earlier point may help.

How to use System Restore:

Boot into the Recovery Environment.
Select Troubleshoot > Advanced options > System Restore.
Choose a restore point dated before the error started.
Follow the on-screen instructions to complete the restore.

System Restore won’t affect your personal files but will remove recent system changes that may have caused the error.

Step 8: Reset Your PC as a Last Resort

If none of the above solutions work, resetting your PC can fix deep software issues by reinstalling Windows.

How to reset:

Go to Recovery Environment > Troubleshoot > Reset this PC.
Choose whether to keep your personal files or remove everything.
Follow the prompts to begin the reset process.

Resetting your PC will reinstall Windows 11 and should fix any persistent boot errors. However, make sure to back up important data if possible before proceeding.
