Hi all. I have a new iMac, and i read an article on how to triple boot it with OS X, XP, and Linux. But then windows wasn't working right. So, I re-partitioned my drive to just my OS X partition. But there is still a partition on my drive named Linux Swap, which I didn't create. But when I boot into my installer disk and then boot up disk utility, the Linux Swap name is grayed out, and I can't delete it. Thanks!
