Hal.dll missing or corrupt for 2001 w-home ed

Hello,
My old laptop that I got in 2001 is not working because of the hal.dll file being missing or corrupted. I have the reinstallation cd, but can not reinstall the file. When I turn on the computer the screen pops up asking what operating system you want and gives you the choice xp home edition or xp setup. When I click on either one I get the error message. I have absolutely no idea what to do next. It says to reinstall the file, but I don't know what happens next. I am not computer savy and need someone to guide me step by step. If you have the patience please email me and tell me what to do. Thanks
