I think this is saying that the fsck command does not know how to check an NTFS filesystem - in other words it cannot find a helper program called fsck.nfts whose job it would be to do the check.

This does not surprise me greatly, as NTFS write capability is still quite experimental, and something like a file system check would need quite in-depth knowledge of the filesystem - something that MS just won't tell anyone.

I think that in order to solve your boot problem you are going to have know what is wrong with it so that you can manually fix it.
