Am trying to get my kids computer fixed but keep getting invalid boot message. Says that <windows root>\system 32\hal.dll is missing or corrupt. Just wanting to know what can I do to fix this issue so that my kids can use the computer. Is there a free download of this anywhere? If so what type of disk do I need to save this on. I'm currently using my laptop. What are the steps needed to download the software using my computer so I can get there other working again. PLEASE HELP!
