Not able to delete XP partition.

Bootcamp Assistant won't let me delete my Windows XP partition.

Let me start with a little background, first. I had 4 partitions before this: Windows 7, XP, Mac OSX, and a 'Storage' partition.

When I deleted Windows 7's partition, XP wouldn't work. After trying for days to try to get it to work, I just gave up and decided to reinstall it.

Only problem is, BootCamp won't let me uninstall it. I've tried following the steps here: http://www.simplehelp.net/2009/01/26/how-to-delete-a-boot-camp-partition/

But Bootcamp comes up with: "The Startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OSX Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows."

Here's my partition setup. Please note that 'Free Space' is where my Windows 7 and Storage partitions were before I deleted them. 'Bootcamp' is XP.




What do I do and how do I remove XP without reformatting the whole drive and reinstalling OSX?

 

It was/is formatted in NTFS. My 'Storage' partition was FAT32, so I could use that to transfer files from OSX to Windows and vice versa.

It won't let me switch it in Boot Camp assistant, if that's what you mean.

If I go to Disk Utility, go under the 'Bootcamp' partition and click on erase...then it'll bring up reformatting options. Is that what I do to make BC Assistant recognize it?
