This will not work; you cannot resize the partitions on a disk that is
in use, so you cannot resize the partitions on a disk containing the
operating system you are using.

You could boot off a live CD (such as Parted Magic), but it seems a
bit of a convoluted process - boot off a live CD to resize partitions,
then boot off a different live CD to install the system - when the
Mint install CD will be able to perform both tasks.
