How to Fix NO SUCH PARTITION (0x000043) BSOD

Method 1: Run System File Checker and DISM

Corrupted system files can trigger this error. Use Windows’ built-in tools to repair them:

Open Command Prompt as Administrator. Press Win + X, then select Terminal (Admin) or Command Prompt (Admin).
Run the following commands one by one, pressing Enter after each:
```
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
```
Wait for the process to complete (it may take several minutes). Restart your PC afterward.

Method 2: Check and Repair Disk Errors with CHKDSK

If file system corruption is suspected, run CHKDSK to scan and repair disk errors:

Open Command Prompt as Administrator.
Run the following command (replace C with your system drive if needed):
```
chkdsk C: /f /r /x
```
If prompted, confirm to run CHKDSK on the next startup. Restart your PC.
After rebooting, check for any reported errors in the Event Viewer (Win + X > Event Viewer > Windows Logs > System).

Method 3: Rebuild Boot Configuration Data (BCD)

A corrupted BCD can cause this error. Use the following steps to rebuild it:

Boot from a Windows installation USB or recovery drive.
In the setup screen, select Troubleshoot > Advanced options > Command Prompt.

Run these commands in order (press Enter after each):

bootrec /FixMbr
bootrec /FixBoot
bootrec /ScanOs
bootrec /RebuildBcd

Restart your PC and check if the issue persists.

Method 4: Update or Reinstall Problematic Drivers

Outdated or conflicting drivers (especially for storage controllers) can trigger this error. Heres how to update them:

Press Win + X and select Device Manager.
Expand Disk drives, Storage controllers, or System devices to find devices with a yellow warning icon (exclamation mark).

Right-click the device, select Update driver, and choose Search automatically for drivers.

If no updates are found or the issue persists, uninstall the driver, then restart your PC to reinstall it automatically.

Method 5: Check for BIOS/UEFI Updates

Outdated firmware can cause compatibility issues. Update your motherboard’s BIOS/UEFI:

Visit your motherboard manufacturers website (e.g., ASUS, Gigabyte, MSI) and search for your model.

Download the latest BIOS/UEFI update and follow the provided instructions to flash it. Use cautionthis process may require a clean power cycle.

Method 6: Test Hardware Connections

Loose or faulty hardware can cause this error:

Power down your PC and open the case (if comfortable doing so).

Reseat RAM modules, SATA/SSD connections, and any expansion cards.

If using a RAID controller or external storage, try disconnecting non-essential drives to isolate the issue.

Test with minimal hardware (e.g., one RAM stick) to rule out memory issues.

Method 7: Check for Corrupted Registry Entries

If the error persists, a corrupted registry entry might be involved. Use caution when editing the registry:

Press Win + R, type regedit, and press Enter.

Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Disk

Look for any entries with incorrect or missing partition paths (e.g., referencing non-existent drives). If found, right-click and delete them.

Restart your PC.

Method 8: Perform a Clean Windows Installation (Last Resort)

If all else fails, a clean install may be necessary. Back up your data first:

Create a backup of important files using an external drive or cloud storage.

Download the Windows Media Creation Tool from Microsoft.

Follow the on-screen instructions to install Windows while keeping your files and apps (if available).
