+Read up on LVM
+The last years i have set up all familys systems using LVM
+It works like this: one or several physical partitions from one or more drives 
+are collected into one pool.
+Then from that pool you create the partitions you need.
+Now comes the big idea: those virtual partitions can easily be resized!
+You can even increase mounted paritions on a runing system using diskdrake!
+I have done so several times.
+
+For shrinking partitions you need to unmount them, easiest is to boot from a 
+live CD/USB.  (well sometimes i have shrunk a mounted partition but i do not 
+understand when it it possible and when not...)
+
+So start out with making relatively small partitions and later increase the 
+one that need be increased.
+
+The partitions you can not have in LVM is of course the one to boot windows, 
+and you also need to have a /boot of 200 MB that can hold grub data and 
+booting kernel and a few alternative.
+
+Warning: In diskdrake you can set up encrypted LVM (check mark for encryptopn 
+when you make a partition to go into LVM) but not edit it.  Encrypt the 
+virtual partition you create from the LVM instead.
+
+The other big advantage of LVM is snapshots.
+But i think you need to use command line to handle them.
+
+google!
