OS X :: Can't Delete Windows XP Folder From Trash

So, while cleaning up my macbook pro from old files, I mistakenly get into the NO NAME partition that appears in the OS X partition, but which holds some kind of Windows XP directories. I don't know how I managed to do so, but I somehow deleted a folder under NO NAME/Documents and Settings/[user name] and all the files in that directory.

Not much harm was done, since it seems as though the folder was merely duplicated into the trash and still remains in its original directory in NO NAME. The problem is that every time I try to delete it from the trash it says I don't have permissions. It's only folders and they're all unlocked and I am logged on as admin. I've tried dragging the folder out of the trash but it merely duplicates it (although I have no issues deleting the duplicate). So I have folders that have no use being in or outside the trash, which are proving to be very difficult to delete. I tried verifying my disk fwith Disk Utility, but it resulted ok.
