How to Restore Hal.Dll
HAL.DLL is a very important Microsoft Windows library file, considering that it manages your operating system's Hardware Abstraction Layer. In simple terms, the HAL is a way for programs to talk to the devices attached to your computer without having to communicate in their language. Often times, HAL.DLL errors might not even be caused by HAL.DLL.

Boot up your computer using your Windows Installation Disk, and when you receive the "Welcome to the Setup" message, press "R." This will start the recovery console. Write the administrator password and press "Enter," and then type "bootcfg /list" and press "Enter." After that, do the same thing, only this time, typing "bootcfg /rebuild."

If all goes wrong, you still have three more options. You can either restore the HAL.DLL file from the Windows disk (in other words, copying the file and overwriting the old HAL.DLL), you can run a repair installation of Windows (if this is available on your version of windows), or you will have to, as a last resort, run a clean, new installation of Windows.

Tips & Warnings
Be sure you understand thoroughly what this article says, or else you might do something you will regret. If you are afraid that you might cause more harm than good attempting this, go to a computer shop and ask one of the people working there to assist you. They will be more than glad to help you.
In Step 5, do not do a clean install of Windows unless you have tried everything else. You must keep this as a last resort. Reinstalling windows without backing up your important files will delete all information on the hard disk if you choose to format it (which would be recommended).
