Problem with windows 2000 repair

Thank you for concern, Unfortunately that was not possible, because the system was halted (windows 2000 doesn't work properly in the begening and all the programs didn't run), in addition to that the computer was an old industrial computer as part of control system, so the source of some programs was not available. I'm afraid that I have to deal with the situation as it is, up to now I reach to that point of file needed "NT5INF.CAT", the windows setup was stop at this point every time I start up the computer,I try to boot in save mode but it deosn't work (blue screen ), so what should I do to continue the setup, hopefully found my setting, its a big change, Please help and thank you a lot.

Thank you for second reply and I hope to get overcome this problem together, It is good idea I will try it although there is some special hardware, Idustrial Ethernet PCI cards to interface with the control system, but I think I could find the drivers in the internet, I may counter some problems with Registry file, you know,I don't have the source or the setup of the control software, so if I just copy the folders to the new drive without installation ,I think I still need to register the software in the registry file of WINNT, I can do that by comparing registry enetry of the old winnt and the new one using Regedit and copy the defference, what do you think? Can you help me dealing with the registry?
I want to ask questuion, after trying to repair the windows and stopped in the middle as I mention before, did the registry of old winnt still good or changed, did it contains the desired registry entries or not?
Thank you my friend, you don't know what what your support mean to me, thank you very much , awaiting your reply.
