corrupt registry in windows xp?

[PablitoX]

Hi everyone, i am new here. I have a problem with mi windows Xp with a message of some unable to find register in:

systemroot\system32\config\DEFAULT

I searched in google in another computer and i found this instructions from microsoft website.

I needed a windows xp cd (i got it from a friend) and with the Recovery Console i had to type:

md tmp
copy c:\windows\system32\config\system c:\windows\tmp\system.bak
copy c:\windows\system32\config\software c:\windows\tmp\software.bak
copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak
copy c:\windows\system32\config\security c:\windows\tmp\security.bak
copy c:\windows\system32\config\default c:\windows\tmp\default.bak

delete c:\windows\system32\config\system
delete c:\windows\system32\config\software
delete c:\windows\system32\config\sam
delete c:\windows\system32\config\security
delete c:\windows\system32\config\default

copy c:\windows\repair\system c:\windows\system32\config\system
copy c:\windows\repair\software c:\windows\system32\config\software
copy c:\windows\repair\sam c:\windows\system32\config\sam
copy c:\windows\repair\security c:\windows\system32\config\security
copy c:\windows\repair\default c:\windows\system32\config\default

and then some other instructions for the safe mode in windows.
However, when i type
copy c:\windows\system32\config\default c:\windows\tmp\default.bak

the console respond with "cannot copy file"

Fine, i searched google again and found this page:

Someone wrote that in that case I should go direct to type

copy c:\windows\repair\default c:\windows\system32\config\default

cause there is no "default" file in the config directory. But when i do that, there is a message "Do you want to replace default file (Y/N)?"

I am confused, there is a default file, but i can not copy to a .bak file?
What do i do now? do replace the file? would there be a problem in the future for doing that?
I can not use windows Xp, not even with the safe mode.
Thanks for any help you can give me, and sorry for my bad english.
