power outage when installing files

I have a Windows NT 4 SP6 workstation. I was installing my digital camera software when the power went out during the middle of installation. I rebooted and windows nt will not start. The error message reads “Windows NT could not start because the following file is missing or corrupt: \WINNT\SYSTEM32\CONFIG\SYSTEM”. I do not have any emergency recovery disk so is there any way to restore my workstation without re-doing everything? I have another NT workstation nearby. If there is a file I can copy from that one, let me know. Thanks
