repartition hard drive?

[DreamSTi]

I have a MBA and I have it dual booting with mac os x and windows 7. When I first had it setup, I used windows a lot and partitioned the hd so most of it was dedicated to win 7, now I use mac os x way more and would like to dedicate most of the hd to os x.

Is there a way to do this without reloading both os's?

I had this all setup for me so I'm not sure how to do this

Disk Utility will let you do it within OS X, you just have to resize it under the Partition Layout.

Did you use Boot Camp? If so, Disk Utility is under the Utilities folder in Applications (or just Spotlight it).

You will want to select the entire drive and not just Macintosh HD or BOOTCAMP. It'll be the very first thing on the list, and the partitions will be listed under that.

Then click the Partition tab (It'll be between Erase and RAID).

Both of the partitions will have a little resize handle at the very bottom on the right. You can either use that, or type the size in GB under the Size field under Partition Information then hit Apply. It'll take a few minutes, and then that's pretty much it.
