Use the Windows Easy Transfer Wizard to save fies and settings from old computer to new one. Programs will need to be reinstalled. Customise the selection if you don't want every file on every drive transfered, if you have a lot of stuff like music and videos on another drive deselect them otherwise Windows will try to backup xxxGB's.
To transfer to a second internal drive or partition, select the external drive option.
I know it doesn't make sense, but it's what you need to do.
