Thanks... this is good to know info :-).

I was able to solve the problem, it was basically a corrupted NTFS
filesystem . I booted into windows and the chkdsk reported errors
specifically for this file and it fixed its indexes (or some similar
message came). I'm not sure how did I manage to corrupt the ntfs
filesystem. The only thing I had done was to delete pagefile.sys and
hiberfil.sys files which were taking  too much space.
