i cannot install new windows xp on any drive(ie D:,E:) of the hard disk, also cannot repair the existing os(ie windows xp sp2) which is installed in
C drive.how i can fix this problem without changing the hard disk? any software available? note that chkdsk utility failed to repair

I tried so-called AntiVirus discs, but they read there are no viruses,
Trend Micro-PC- cillin Internet Security reads 247 viruses in WR.

I had the Total Security/Anti-Virus Pro_2010 rogue virus which I have removed with mulitple programs and then did a registry clean with COMODO but now my Autoplay camera wizard is not automatically popping up like it always has in the past. I ran an Avast scan which found no infected files but also could not scan 44 files. Before this virus Avast always could scan all my files and never showed these "unscannable" files. On a forum I saw that someone provided a forum moderator specialist who was helping them remove their virus the same list of files as mine (in the same order too) from some type of file check they do to figure out how they want to attack and remove the virus. This fact makes me sure that this must be part of my problem. Any info on how to fix this situation would be greatly appreciated. Here are the unscannable files:

I restarted my pc and got this error message "Windows could not start because the following file is missing or corrupt : \WINDOWS\SYSTEM32\CONFIG\SYSTEM
You can attempt to repair this file by starting Windows Setup.
Select ‘r’ at the first screen to start repair."
Then I followed these steps :

Boot to the Recovery Console.
At the Recovery Console command prompt, type the following lines, pressing ENTER after you type each line:
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

My problem is after typing
copy c:\windows\system32\config\security c:\windows\tmp\security.bak then i press enter it says "the system cannot find the file specified" and so on the c:\windows\system32\config\default.
Please Help
