Click on Disk Management System
I have covered a few possible scenarios you might face.
[list][*]You have a 40 GB hard disk made into four more or less equal partitions. You can see your partitions and their corresponding drive letters (C,D,etc.) in the figure below.
The idea is to free at least 20 GB for our linux install. This might seem like a lot and other's might disagree, but if you are looking for a full experience I'd recommend it. We will need this space later to make three partitons
Swap - Space=1.5 to 2 times your RAM
Root (designated as /) - stores your OS and system files, programs, etc. - Space approx 8GB
Home (designated as /home) - like the Documents and Settings folder of Windows XP. Stores your preferences, bookmarks, wallpaper, My Documents and Desktop. - Space - remaining space
The / is like the base directory in linux, into which all other directories (folders) are incorporated or "mounted". I took a very long time to understand the concept of "mounting". Don't worry about it for now, you will understand when the time is right.
So here you will have to backup the data in the last two partitions by writing it to a CD or DVD or copying to another hard disk, and delete them as shown below
