never mind...problem solved...
for those who might experience such a problem though, i downloaded Paragon Partition manager.
it was pretty simple from there...(only that it took 3 hours to create that 60 gb partition...but apparently cuz it shud be 'at the end' (so that it doesnt cause boot problems) so apparently the wizard had to 'copy' the content of all other partitions onto new ones or smth like that....
