In the Windows operating systems, the HAL (Hardware Abstraction Layer) file is an important component that acts as the the link between the hardware components and the operating system. Apart from this, it also provides support for the hardware drivers that are required to run certain hardware devices.
This file is installed in the hard disk when it is fresh and needs to made compatible to work in a Windows environment. Hence, when this file is not found on the hard disk then you are unable to start the system if the hard disk is the boot device. In such scenarios, you should use a professional hard drive data recovery software to perform hard drive recovery.
Let us analyze a scenario in which you are trying to upgrade your Windows version from Windows 98 to Windows XP. But when you start the system, it fails to start. An error message is displayed in this case, which is:
Windows could not start because the following file is missing or corrupt.
Windows root\system32\hal.dll.
Please re-install a copy of the above file.
Cause:
There could be the following reasons for this erroneous situation:
You have restarted your computer after upgrading from Windows 98.
The hard disk on which you are trying to install Windows XP does not have any operating system.
Resolution:
To resolve this situation, you should perform either of the following methods:
Modify the BIOS settings so that you can start the system from a Boot CD.
Restart the system using the Windows 98 Setup CD.
Type 'sys c:' at the command prompt to copy the system files from the CD to your system.
Start Windows XP Setup again.
Select to format the hard disk before installing Windows XP.
Restart the system after installing Windows XP.
If you are still unable to start the system even after following these methods, then that means the hard drive is corrupt and you need to replace it. However, before replacing the hard disk you would need to recover and backup the data.
For this, a third-party hard drive data recovery software is very useful in recovering the inaccessible files. These
HDD recovery tools have immaculate user interface that enable an end user with limited technical skills to recover the data easily.
