This should not be attempted on xp OEM.

Windows XP could not start because the following file is missing or corrupt:
\WINDOWS\SYSTEM32\CONFIG\SYSTEM or, at the end, instead of SYSTEM, you may see something else.

Repair the problem by using Recovery Console. For this you will need xp installation CD. If you don't have the CD try to borrow one.

To get to Recovery Console insert the disk into the cd drive and reboot the computer. Setup Windows screen will show up. If it doesn't, enter BIOS and set the cd drive to be first priority boot device.

Let Setup run until three setup options are shown. Choose Recovery Console by pressing R. When asked for XP installation type 1 (assuming you have only one operating system installed). When asked for password type your password or press Enter if you don't have a passwoed. A black DOS-like screen will show up.

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

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

Type exit to quit Recovery Console. Your computer will restart.

Another Method you can try is

This one

I like this method better because it does not default your registry less likelihood of destroying some of your programs configuration.
