In command promt (Administrator:X:\windows32\cmd.exe) write command: c:\windows\repair\sam c:\windows\system32\config\sam
The system can not find the path specified.

You didn't type it write. Forgot to include "copy" in the command. Type this exactly as you see it:

copy C:\Windows\repair\sam C:\Windows\system32\config\sam

If it doesn't allow you to overwrite, use this command:

copy /y C:\Windows\repair\sam C:\Windows\system32\config\sam

Go to the root of the drive in a command prompt
(by typing "cd \" without the quotes,and hitting Enter)
and do
"dir filename /s"

where filename is the file you're searching for.
That should search the entire disk. If you don't find it,
try using /AH switch to show hidden files as in
"dir /AH filename /s"

If it ain't there, it ain't there.

Well, did not find "repair", "repairfolder".
In C: find one file SAM(262 kB) in C:\Windows\System32\config,
and second SAM files (29kB) in C:\Windows\System32\config\RegBack
What to do now?
Appreciate your help, and thanks so much.
Regards

See SAM in:
C:\Windows System32\config, and in
C:\Windows System32\config\RedBack

The file exists, here's a screenshot. You might be getting trouble because it doesn't have an extension. Also, you need to allow admin privilege to view the folder:

It's look that I can not do anything. Is there method to start Win7 from command prompt?

If there's an essential file missing, it won't boot at all until you fix it.
