\WINDOWS\SYSTEM32\CONFIG\SYSTEM error

[iTz TaLeNt]

I have Windows XP Home Edition
I use Zonealarm security suite as my antivirus/firewall
My Computer is an hp pavilion zv6130us
-AMD Athlon 64 Processor 3200+ 2.0 GHz and 512KB L2 Cache
-80Gb (4200RPM) Hard Drive
-512MB Memory
-Microsoft Windows XP Home Service Pack 2 with Advanced Security Technologies

Leading up to this, my cmd prompt and regedit would open then close automatically about a half/second after opening so i was trying to fix this and i forget why but i went to http://support.microsoft.com/kb/223188 and followed the instructions. I downloaded a backup from http://www.dougknox.com/xp/utils/xp_emerutils.htm and from http://service1.symantec.com/SUPPORT...rc=sec_doc_nam before i messed with the Registry. Then I got stuck at the Windows XP screen, so then i tried to start my PC in safemode, Last Known Configuration, and Start Windows Normally. None worked so i put in my Windows XP disk and tried repairing by typing-

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

All of them worked except copy c:\windows\repair\system c:\windows\system32\config\system wasnt able to be copied at the end. It said the system cannot find the file specified.

And now im getting a black screen with a message saying Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM.

Also if it helps I ran chkdsk /p and it said chkdsk found one or more errors on the volume

Ive tried everything and went everywhere trying to fix this, i got stuff on my pc i really need back, you guys are my last hope.

Thanks
