Linux Mint Installation - Can't partition the disk back to normal

I'm going to go ahead and say that curiosity definitely killed me this time. I wanted to install my favorite distro of linux (Mint 6.0). I used boot camp to do so and in doing so I created some swap space and a /home and / partition. After doing so I booted up and it worked absolutely fine. However, I only have a 100GB hardrive with my macbook pro and I decided I wanted to get rid of it. So I went into disk utility and tried to "-" the linux made partitions.

I have tried this over 10 times and each time I try to delete any of the partitions disk utility hangs up on "Preparing to delete the volume" and it never does. I left it working for almost an hour and nothing happened.

I just want to delete the partitions and restore the full 100GB to OSX. What did I do wrong and how do I fix it?

Edit: Also, I tried to run off boot camp again with the linux disk in there to try to clear out the partitions with the advanced partition manager and that didn't help at all. Now whenever I start my laptop a gray folder appears in center with a white question mark over it and after about 1 minute the apple log appears and osx starts up fine.
