Dupe of @fossfreedom's one. @Lekensteyn, that one refers to a standalone install. – Rory Alsop Apr 18 '11 at 22:08

(answer taken from SuperUser)

According to this guide, you can use LVPM

As an alternative, you can use the following script to move /home to a dedicated virtual disk.

Download wubi-add-virtual-disk, open a terminal and run:

sudo sh wubi-add-virtual-disk /home 15000

Where the first argument is the directory to move to a new dedicated disk, and the second argument is the size in MB.

You should now reboot. If you are happy with the result, you can now remove /home.backup. To undo the changes remove /home, copy rename /home.backup to /home and remove the /home line in /etc/fstab.
