Resolution

1. Restart the PC. The hal.dll error could be a fluke.

2. Check for proper boot order in BIOS. You might see the hal.dll error if the boot order in BIOS is first looking at a hard drive other than your main hard drive.

Note: If you've recently changed your boot order or recently flashed your BIOS, this may be what's causing your problem.

3. Run Windows XP System Restore from a command prompt. If this doesn't work or you're receiving the hal.dll error message before you're able to complete this process, move on to the next step.

4. Repair or replace the boot.ini file. This will work if the cause of the problem is actually Windows XP's boot.ini file and not the hal.dll file, which is often times the case.

Note: If repairing the boot.ini does correct the hal.dll issue but the problem reappears after a reboot and you've recently installed Internet Explorer 8 in Windows XP, uninstall IE8. In this specific situation, IE8 could be the root cause of your hal.dll problem.

5. Write a new partition boot sector to the Windows XP system partition. If the partition boot sector has become corrupt or isn't properly configured, you may receive the hal.dll error.

6. Recover data from any bad sectors on your hard drive. If the physical part of your hard drive that stores any part of the hal.dll file has been damaged, you're likely to see errors like this.

7. Restore the hal.dll file from the Windows XP CD. If the hal.dll file is truly the cause of the problem, restoring it from the original Windows XP CD may do the trick.

8. Perform a repair installation of Windows XP. This type of installation should replace any missing or corrupt files. Continue troubleshooting if this does not resolve the issue.

9. Perform a clean installation of Windows XP. This type of installation will completely remove Windows XP from your PC and install it again from scratch.

Note: While this will almost certainly resolve any hal.dll errors, it is a time consuming process due to the fact that all of your data must be backed up and then later restored.

Important: If you can't gain access to your files to back them up, you should understand that you will lose them all if you continue with a clean installation of Windows XP.

10. Test the hard drive. If all else has failed, including the clean installation from the last step, you're most likely facing a hardware issue with your hard drive but you'll want to test it to be sure.

If the drive fails any of your tests, replace the hard drive and then complete a "new" installation of Windows XP.

Time to get out that restore disc you made when you first got your laptop. The boot sector has errors. Boot with your rescue disc and run CHKDSK/F to clear the errors.
Hope that helps.

CauseCauses of the "missing or corrupt hal.dll" error include, naturally, a damaged hal.dll DLL file or a hal.dll file that has been deleted or moved from its intended location. Additional causes may include a damaged or missing boot.ini file or possibly a physically damaged hard drive.

for that you need winxp bootabler disk.
Tehn boot your computer with tht and go to recoverry console.
Then type in command prompt "chkdsk /r"
then press "y"
then it fixc error on harddisk.
Then after completing it restart your computer and boot with harddisk then it ok.

1. Verify the boot.ini file is found on the computer by using a boot diskette or use your Windows CD to get to the MS-DOS "C:\>" prompt.
2. From this prompt edit the boot.ini, verify that it is pointing to the correct operating system, and that no anomalies are found within the file. Below is a listing of what to verify

• If only one operating system is on the computer verify that the boot.ini only has one operating system listed. In some situations an alternate configuration line may be added for the same operating system, leaving the improper line.
• Verify that the "default=" line as well as the operating system line are the same and that they are pointing to the correct operating system.

Verify that the computer has the hal.dll file

From the MS-DOS "C:\>" prompt quickly determine if your computer has the "hal.dll" file by typing "dir hal.dll /s" at the prompt. If the computer returns a "File not found" message, the hal.dll has been deleted.

To recover this file boot the Windows operating system CD and choose the option to "Restore", "Repair", or "Recover." This option will prompt you for the Windows installation to use, the administrators password and will allow you to restore the proper file. At the MS-DOS prompt type the below command.

expand C:\i386\hal.dl_ D:\windows\system32\

In the above example "D" would be the letter of your CD-ROM drive and "C" the letter of the drive your operating system is installed on. For example, your disc drive may be D: and your hard drive is likely C:.

There's actually a number of reasons why these annoying little DLL errors happen, but the most common, is caused when new programs are installed over all old ones and the old ones are not completely uninstalled 100%, causing registry pile ups and of course, getting a .DLL error messages.

Another reason, is damage that's been done by malware/spyware/adware programs, attaching themselves to your PC and wrecking havoc, deleting crucial DLL files from your PC.

The hal.dll file is created during install from 5 other dlls. HAL is the Hardware Abstraction Layer and it's the interface between the system drivers and the actual hardware.

Copying hal.dll will not resolve the problem.

A lot of times the file will be reported missing due to corruption of the boot sector or of the file system

Causes of the "missing or corrupt hal.dll" error include, naturally, a damaged hal.dll file or a hal.dll file that has been deleted or moved from its intended location.

Additional causes may include a damaged or missing boot.ini file or possibly a physically damaged HDD.
