Please edit your message with a better title (and correct spelling). As it is, it looks like you are looking for a job ("want work")

Reading your message, you mean won't work.

Also, please use capitals, punctuation, etc.

Here is my attempt at translating your post:
Answer:
What operating system are you using?
What "repair boot CD" are you using?
Describe in detail what was the original problem, what you did, and what happened at each step.

Without providing more meaningful information its going to be impossible to help you.
