I have tried to run sfc /scannow.  After it finishes scanning, it asks me to put the Windows XP Professional CD2 in the drive.  All I have is the Operating System Reinstallation CD for XP Media Center Edition 2005, which it rejects.

 

I have followed the advice to go into the registry to modify two keys: HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENT VERSION\SETUP and HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWSNT\CURRENT VERSION to change the SourcePath to C:\, but after scanning it still fails to replace files.

 

I also tried copying the entire DVD to a new folder in my C: drive in the hopes that sfc could find it, yet it still won't accept it.

 

What am I doing wrong?
