Hey all: I've got a good system w/ WinXP installed. Good anti-virus software, etc but I get home today and I find that my comp is telling me that my "hal.dll" file is missing/corrupt. I've run the recovery console from my Windows CD, and input copy e:\i386\hal.dl_ c:\windows\system32 Copies successfully. but then I reboot, and nothing has changed. I read all this stuff online where it tells me to 'expand' rather than 'copy'. So I do: expand e:\i386\hal.dl_ c:\windows\system32\hal.dll expand failed. It wont do it. I also cant bootcfg /rebuild Errors occur. So, why wont it 'expand' ? What can I do? THANKS SO MUCH.
