Try this:
Get into the Command Prompt. Once you're in, do the following:
From the C:\ drive: type:
C:\cd /Windows/System32/Drivers (enter)
C:\Windows/System32/Drivers: ren ntfs.sys ntfs.old (enter)
C:\Windows/System32/Drivers cd.. (enter)
C:\cd /i386 (enter)
C:\i386 Expand ntfs.sys C:\Windows\System32\Drivers (enter)
You should be all right after replacing the faulty ntfs.sys in your Windows/System32/Drivers folder.
What the command line above does is to extract from the folder i386 a clean copy of the NTFS.sys file and transfer it to C:\Windows\System32\Drivers folder.
Folder i386 contains all the OS files (7,505 files in 11 directories).
These files are all compressed (like cabinet files), and need to be extracted in order to have them functioning normally.,
