How to reinstall Dll

[jbar1]

Had a sever power outage and after rebooting got this message
The following file is missing or corrupt

windows root\system32\hal.dll
Cant get consul to run so any ideas on how to fix this?
Thanks

OK got the hal.dll prob solved and system is more or less as it should be. Installed a second xp sys on same drive took ownership and fixed original with no loss of important stuff. Now bootup is a bitch as a new window ask which XP pro to boot. How do I uninstall the second system I just put on. Yes I know I should have installed it on a bench drive however what is done is done. Any help
Thanks

Do you ahve a setting for PIC / APIC in your bios?

This error usually occurs after changing from APIC back to PIC.

YOu could have resolved this by setting the bios setting back to APIC and then using the recovery console, run a chkdsk /r.

I have fixed this same scenario many times with these steps. Cusotmer upgrades BIOS, or just loads defaults, and they lose the APIC setting. Once windows is installed with APIC, you cannot set it back to PIC with out damaging the os.

Dont confuse this with ACPI which is not the same thing.

If your MB does not have a PIC/APIC setting, then this is not the answer.
