How to partition ?

[kikloo]

Hello,

I have a 300 GB hard drive and 3 GB RAM and its Core2Duo processor on which I have created 3 partitions when I installed Windows.

1. C: - 100 GB in which Windows is installed.
2. D: - 100 GB in which I have kept my personal stuff.
3. Unallocated space of 100 GB.

I want to install Ubuntu in this un-allocated space. How do I proceed for dual booting ? I do not understand how to create partitions, please guide me.

Please guide.

Thanks.
