update- so i actually replaced that file using recovery console and the exited the recovery console. i booted the pc and then it gives me several selections of boot in last known good, safe mode etc, i selected both of these modes and then it just boots back round again. stating theta system 32\drivers\ntfs.sys is corrupt or missing.
can i reload the same version of windows on the current os partition? that isnt advisable is it?
May i add that chkdsk states the drive is fine, have had it attached to anothe pc via ide to usb and extracted all the data.
