How to Fix or Restore BootMenuUX.dll

Repairing the BootMenuUX.dll issue depends on the cause of the error. Follow these proven methods to fix the file and restore normal system functionality:

Windows includes a built-in tool called System File Checker that automatically scans and repairs corrupted or missing system files. To use it:

1. Press Windows + X and select Command Prompt (Admin).
2. Type sfc /scannow and press Enter.
3. Wait for the scan to complete. If any damaged files are found, Windows will replace them automatically.

2. Use DISM Command to Repair the System Image

If the SFC scan cannot fix the problem, use the Deployment Image Servicing and Management (DISM) tool to repair the Windows system image:

1. Open Command Prompt as Administrator.
2. Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
3. After completion, restart your computer and rerun the SFC command to finalize the repair.

3. Restore BootMenuUX.dll from a Trusted Source

You can download a verified copy of the BootMenuUX.dll file from the official Microsoft installation media or from a reputable DLL library that offers authentic and virus-free system files. Always avoid random third-party sites that distribute DLLs, as they might include harmful code.

After downloading, place the file in the correct system directory:

• For 64-bit Windows: C:\Windows\System32\
• For 32-bit Windows: C:\Windows\SysWOW64\

4. Run a Malware Scan

If malware or adware has replaced or deleted BootMenuUX.dll, a complete antivirus scan is essential. Use Microsoft Defender or a trusted security suite to remove any malicious software. Once cleaned, reinstall or restore the DLL file as described above.

5. Reinstall or Repair Windows

If none of the above solutions resolve the issue, consider performing a Windows Repair Install or Reset. This will restore missing system files without affecting your personal data. Always back up important files before proceeding with system-level operations.
