Well, I am not too sure from an NT to Unix..but when I move my databases between my boxes, all I do is this. from the bin directory of your mysql install...
./mysqldump database > location where you want the file to go
Then from the unix prompt. also be in the bin directory again.
first, create the database.
then type
./mysql database < location/filename
That will load all table structure and data in to the db
