If you have one single hard drive split into two partitions, you will have
to use a program like Partition Magic, Acronis Disk Director, or Bootit NG
to increase the size of your primamry partition..
Use of the above requires that you complete a full system backup or risk
losing everything..
Rather than mess with partition sizes, you could simply move data like the
contents of 'My Documents' to the other partition.. here's how..

Moving programs involves uninstalling from their present partition, and
re-installing (using the CUSTOM option) on the other partition..
