The system indicates that the “hal.dll” file is missing, and Windows cannot start.

The error message suggests that the “hal.dll” file, which stands for Hardware Abstraction Layer Dynamic Link Library, is missing or corrupted. This file is crucial for the proper functioning of Windows. Here are steps you can take to address this issue:

1. Use Windows Installation Disc/USB:
   Insert your Windows installation disc or USB drive and restart your computer. Boot from the installation media and choose the “Repair your computer” option. From there, you can access the Command Prompt.
2. Command Prompt:
   In the Command Prompt, type the following commands:

   cd C:\Windows\System32
   ren hal.dll hal.dll.old

These commands rename the existing “hal.dll” file to “hal.dll.old.”

3. Copy Hal.dll from Installation Media:
   If you have access to another computer with the same version of Windows, you can copy the “hal.dll” file from that system. Replace the missing file on your computer with the one you copied.
4. System File Checker (SFC):
   Run the System File Checker (SFC) utility to scan and repair system files. In the Command Prompt, type:

   sfc /scannow

Allow the scan to complete, and follow any prompts to fix detected issues.

5. Check for Disk Errors:
   Use the CHKDSK (Check Disk) utility to check for and repair disk errors. In the Command Prompt, type:

   chkdsk /r

This process may take some time. Once it’s complete, restart your computer.

6. Perform a Repair Installation:
   If the issue persists, you may need to consider performing a repair installation of Windows. This process allows you to reinstall Windows without losing your files and applications.

Remember to back up important data before attempting any major changes to your system. If you are not comfortable performing these steps, or if the issue persists, consider seeking assistance from a knowledgeable friend or a professional technician.
