You should be able to delete the partition using this util

I haven't used it for a longtime so you might want to read the text file. Once removed, you should then be able to use Partition Tragic to extend the main volume. Only issue you might have is with the bootloader if you haven't fixed this already from Vista to XP.

Sorry I can't be more help, but I'm up to my ears in fooked servers at the moment.
