Merlin:
It seems that the C:\WINDOWS\SYSTEM folder was deleted. If this is correct, then repairing the registry won't bring it back.

OK, maybe i'm missing something, but it seems you have deleted the folder that contains the system files Windows 98 needs to function. To test this, i booted one of my systems with Windows 98 SE on my home network with a Windows Me boot diskette. I then typed c: and pressed ENTER and then dir system /s and pressed ENTER, and i received the following result:
Directory of C:\WINDOWS
SYSTEM <DIR> 01-20-04 8:28p
SYSTEM INI 1,818 04-15-05 12:51P
1 file(s) 1,818 bytes
Directory of C:\WINDOWS\SYSTEM
SYSTEM DRV 2,288 04-23-99 10:22p
1 file(s) 2,288 bytes
Total files listed:
2 file(s) 4,106 bytes
1 dir(s) . . . bytes free
It appears, then, that you do not have the system directory (i.e. the sytem folder, which is indicated by <DIR>). All you have is the system.ini file.
So, the only way to get Windows 98 to work is to restore a backup (if you have one on CD) or to reinstall Windows 98 using the installation CD (which they should have at your place of work).
If you need advice about reinstalling Windows, let Merlin or i know.
