Removing partitions on a hard drive can be a bit tricky on Windows and you need to be very careful doing this as you may end up wiping out your drive and all it's data inadvertently. There are a number of third party software packages that can help you with this task (like BootDisk.com or Partition Magic.) Windows Vista and Windows XP also have some built in tools (look under Administrative Tools.) Please note that removing partitions can be destructive and irreversible. It's best to get someone who has experience with this to help you.
