Not at all a typo. Lack of knowledge !

Well, this for sure will install in the main /dev/hda5, which I can not hide 
during this process. The point is, I am trying to install really 
to /dev/sda5, which should be something like grub> root ( sda0,4).
Any way to perform this ?
Thank you very much for the help, as well as to Lauri's comment.
