If you mean you want to resize the partitions your Linux is using, then I agree with mostly with the previous poster but you can do a hybrid if you want to save your data without actually reinstalling and if you have another drive that's big enough.
Get rsync and copy your system to the other drive. (This can also be over a LAN to another box, rsync works great)
Repartition your main drive
make filesystems in the new partitions
rsync everything back
fix your bootloader and fstab as necessary
