I recently tried to make a triboot system on my MacBook Pro (mid 2010) running Ubuntu, OS X, and WinXP. Unfortunately, it broke the windows (which was already there with bootcamp) and then Ubuntu broke so I decided to repartition my drive just with mac and start from scratch. At first I had an issue of the partitions refusing to delete but I fixed that with a tip in another forum (reformat all drives to HFS+). However diskutil gives me errors, when I try to make use of the free space leftover either by adding a new partition (it only resizes it to 2GB) or when I try to resize the current one (Partition failed with the error: MediaKit reports partition (map) too small). YES I have tried booting into Mac CD and repartitioning from there. HELP please
