How to Restore Hal.dll From the Windows XP CD

The hal.dll file is a hidden file that Windows XP uses to communicate with your computer's hardware. If the DLL file gets damaged, corrupted, or deleted, you will receive a “missing or corrupt hal.dll” error message. Follow these steps to restore the hal.dll file from the Windows XP CD using the Recovery Console.

Hall.dll errors can occur on Windows 10, Windows 8, Windows 7, and Windows Vista; however, the process for fixing hal.dll errors in Windows 7, 8, 10, and Vista is different.

How to Restore Hal.dll From a Windows XP Disc

To restore a missing hal.dll from the Windows XP Recovery Disc:

Insert the Windows XP Recovery CD into your disc drive.
Enter the Windows XP Recovery Console.
When you reach the command line prompt, type the following and press Enter:
```
expand d:\i386\hal.dl_ c:\windows\system32 
```
In the expand command above, d: represents the drive letter assigned to the optical drive that your Windows XP CD is currently in, and c: represents the drive that Windows XP is currently installed on. The drive letters may be different on your computer.

Spaces are needed between the expand command, the path to the optical drive, and the c:\windows\system32\ path.
Type Y if prompted to overwrite the file.
Remove the Windows XP CD and type exit, and then press Enter to restart your PC.

Assuming that the missing or corrupt hal.dll file was your only issue, Windows XP should now start normally.
