    Alright guys, I need a hand. A while back, using bootcamp, I decided to re partition my hard drive and install myself ubuntu. However, I messed up a little bit, and now i've made a mess of things. When I open disk utility, my harddrive now as three partitions: Macintosh HD - formatted Mac OS Extended (Journaled) - 181.9 gb. disk0s3 - formatted MS-DOS(FAT) - 48.7 gb. Linux Swap - formatted Mac OS extended (Journaled) - 2.1 gb. The second disk has nothing on it, and the linux swap is about half full. I also employed reFit on startup to choose between mac and linux, but I do not remember what its called.

    What I would like to do whatever i can to get my harddrive to once again be completely dedicated to Mac OS. I want to delete the other partitions, and have everything back to normal.

    launch disk utility, select your internal drive and go to the partition tab

    highlight the volumes you want to remove and simply click on the minus tab at the bottom

    once you are left with just your mac os x bootable volume drag the partition to fill the whole drive again

    btw, the disk0s3 is more likely an ext3 or ext4 partition. The OSX disk utility is unable to read ext partitions so it reports it as a fat partition

    I had this same problem in the past when I tried out Ubuntu. What you need to do to free up the Linux partitions is boot into the Linux distro setup program and format the partitions as FAT so you can then use Disk Utility afterwards to delete them and recombine the space into one partition. If it won't let you format as FAT I think you can simply just delete the partitions within the same Linux disk setup program.
