Hi Kellymac,

GParted should be able to do that for you.

Here is a tutuorial - you shouldn't need to do the startup repair mentioned as installing Win 7 afterwards obviates the need for that.

Using GParted to Resize Your Windows Vista Partition :: the How-To Geek

This is the version of Gparted I have used - direct d/l GParted: Downloading ...

Here's the direct d/l for a tiny free isoburner - works great , just runs straight away - I use to burn iso to cd all the time

For anyone not familiar with burning bootable .iso files, don't format the cd, if Autoplay pops up, just close it

Hope it helps

Also try Defraging it. Sometimes the drive needs it and in built partitioning tools won't be able to defrag it automatically so it tells you there isn't adequite room. I use Acronis Disk Director and it's bloody great..
