thanks for the idea, but.....
update...... downloaded remix rescue and have been playing with
testdisk.  (nice utilities! by the way) apparently this kid tried to
install osx over windows because its reporting an HFS filesystem that is
"unrecoverable"  got the same thing from chkdsk under recovery console.
thanks for the advice, i think im going to write this one off...
