Ruby - DOS (Win32) path name to NT (native) path name

I need to get the NT (native) path of a file from the DOS (Win32) path in Ruby (1.9.3).

Meaning, I have the string:

dos_path = "C:\Windows\regedit.exe"

but I need:

nt_path = "\Device\HarddiskVolume1\Windows\regedit.exe"

Is there any way to do so? Thanks!
