Formatting System Drive help

On my main hard disk I have three partitions for two different OS’s and data storage. I’ve got XP and Vista, as I’m not using XP any more, I was going to delete that partition. But I can’t get it to delete or format, I tried through the disk management tool, also tried KillDisk. Any suggestions short of taking an OS install disk and formatting it that way, or wiping the entire drive?

It’s gonna take some fiddling.

You’ll need to set the Vista partition to “active”.
