Windows could not start, I don’t have original CD, how do I fix this please?

While i start upward my desktop, I obtain the message:

“Windows would not want to start for the reason that following document is not well-known or dodgy:

\WINDOWS\SYSTEM32\CONFIG\SYSTEM

It is possible to attempt to be able to repair the following file by means of starting Windows Setup with the original CD-ROM.Select “r” on the first screen get started on repair”

However I don’t possess the unique CD, is there another way around this
