Fix booting of bootcamp partition?

I recently, very stupidly, created another partion on my mac for no reason. It has now broken the bootcamp partition (It won't boot, does not show up in the option menu at boot). I cannot get it to fix using the windows installation disk or anything like that, so I was wondering what are my options to restore the bootcamp partition.

Any advice would be greatly appreciated, as I have some important stuff on there that I need to use. I don't want to back up my data and reinstall.

This is my partition layout:

(Note that I am also unable to get rid of the free space, if i drag the mac partition and press apply, it just undoes)
