How to Fix Invalid Partition Table Error on Windows 11: Step-by-Step Solutions

Encountering the “Invalid Partition Table” error on Windows 11 can be frustrating. This error usually appears during startup and prevents your computer from booting properly. It often indicates a problem with the disk’s partition table or boot configuration.

Fortunately, there are several step-by-step solutions you can try to fix this issue. This guide will help you understand and resolve the problem in simple terms.

Before diving into advanced solutions, it’s best to start with the easiest fixes. Following each step carefully will increase your chances of restoring your system without data loss.

Let’s begin by checking some basic points to ensure you’re ready to troubleshoot effectively.

Quick Note: Prerequisites and Initial Checks

  • Backup Important Data: If possible, back up your files using an external drive or cloud storage. This is important because some fixes might risk data loss.
  • Confirm the Error: The “Invalid Partition Table” message usually appears on a black screen during boot. Make sure this is the exact error before proceeding.
  • Check Your Connections: If you recently opened your computer, verify that the hard drive cables are properly connected.
  • Have Windows 11 Installation Media Ready: You may need a USB or DVD with Windows 11 installation files for some repair steps. You can create this using Microsoft’s Media Creation Tool.

Step 1: Restart Your Computer

Sometimes, a simple restart can resolve temporary glitches affecting the boot process. Press the power button to shut down your PC completely, wait about 10 seconds, then turn it back on.

If the error persists, move on to the next step.

Step 2: Check BIOS Boot Order

The BIOS controls how your computer starts up. If the boot order is incorrect, your system might try to boot from the wrong device, leading to errors.

  1. Restart your PC and press the key to enter BIOS or UEFI settings. This key varies by manufacturer but is often F2, Delete, or Esc.
  2. Navigate to the Boot or Boot Order section.
  3. Ensure your primary hard drive (where Windows is installed) is set as the first boot device.
  4. Save changes and exit BIOS.

Reboot and see if the error is resolved.

Step 3: Use Windows Automatic Repair

Windows 11 includes a built-in tool called Automatic Repair that can fix common startup problems.

  1. Insert your Windows 11 installation USB or DVD and restart your PC.
  2. Boot from the installation media by selecting it in the boot menu.
  3. When the Windows Setup screen appears, click Next, then click Repair your computer at the bottom left.
  4. Choose Troubleshoot > Advanced options > Startup Repair.
  5. Follow the on-screen instructions. Windows will try to detect and fix issues automatically.

If Startup Repair does not fix the problem, continue to the next step.

Step 4: Repair the Master Boot Record (MBR) and Partition Table

The “Invalid Partition Table” error often means the Master Boot Record or partition table is corrupted. You can fix this using Command Prompt from the recovery environment.

  1. Boot from the Windows 11 installation media again.
  2. Go to Repair your computer > Troubleshoot > Advanced options > Command Prompt.
  3. In the Command Prompt window, type the following commands one by one, pressing Enter after each:
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

These commands will repair the boot sector and rebuild the Boot Configuration Data (BCD).

Note: If bootrec /fixboot returns an “Access Denied” error, try these commands:

diskpart
list disk
select disk 0
list partition
select partition 1
active
exit
bootrec /fixboot

This marks the correct partition as active and attempts the fix again.

After running all commands, close Command Prompt and restart your PC.

Step 5: Run CHKDSK to Check and Fix Disk Errors

Disk errors can also cause partition problems. Running the CHKDSK utility scans and repairs file system errors.

  1. Access Command Prompt from the Windows recovery environment as above.
  2. Type the command and press Enter (replace C: with your system drive letter if different):
chkdsk C: /f /r

This command fixes errors (/f) and recovers readable information from bad sectors (/r).

Wait for the process to complete, then restart your PC.

Alternative Method: Use Third-Party Partition Repair Tools

If Windows tools don’t help, you can try trusted third-party software like MiniTool Partition Wizard or EaseUS Partition Master. These tools offer user-friendly interfaces to repair partition tables and recover lost partitions.

Make sure to download software from official websites and carefully follow their instructions.
