What it's trying to tell you is that your drive is too fragmented to get a clear 7GB (*way* too small BTW) partition for Windows.
The cheapest way I know to solve this problem:
1. Use SuperDuper
or Carbon Copy Cloner
to make a bootable clone of your hard drive onto an external drive. Both are free to make a master clone. You should buy/donate if you're going to use it regularly.
2. Boot from the clone in order to test it, then ERASE (zero out) the boot drive.
3. Use SD or CCC to restore to the freshly-erased boot drive and reboot.
NOW you should be able to set up the partition you want. One *very important* caveat: make SURE you have ***at minimum*** more than 10GB free space AFTER the partition is created. Mac OS X needs room to work and anything under 10GB is asking for trouble.
Normally, Macs don't really need to be defragmented (or very rarely) but setting up a live partition on the boot drive requires "contiguous" space which can be hard to come by on a Mac that's been used for a while.
