I own a DELL XPS 400 - OS Windows XP. 

About a week ago, I changed the system's hard drive and reinstalled the OS using DELL's Recovery DVD. Additionally, I updated the system by installing the DELL DSS, updating and downloading drivers. However, over the past few days I have been getting a message upon boot-up; the message is "Windows couldn't start because the following is corrupt or missing -- System32\drivers\ntfs.sys. Please insert Windows XP CD and type r to repair."

I am not sure if this issue can be fixed (repaired) using the DELL Recovery CD and how, or if I should reinstall Windows (clean install).

Thank you for your help.
