I have an XP Pro SP2 machine, and when I tried to boot it up it says 'file ntfs.sys is imssing or corrupt blah blah blah '. I tried to boot of the XP Pro CD, but after loading all the installation drivers, it too says 'file ntfs.sys is corrupt' and doesnt even get me as far as the recovery console. The CD is good, because we just installed off it on another machine not 15 minutes ago.... Help!!!
