which distribution of Linux you are trying to install, if you are installing Ubuntu i recommend you use live CD or you can install it on same partition (w/ windows on it) without creating new partition.

To install linux you do not need to create new partitions cos linux can use same PC hardware. Just install it on a different folder.
