Can't boot windows xp after installing ubuntu 12.04

view story

http://askubuntu.com – So I installed ubuntu 12.04 alongside windows xp and I played with it for a like an hour and when I wanted to go back to windows I choose the windows option in the grub screen and it just gives a black screen and goes back to grub. I tried boot-repair as i've seen in some other post that it could resolve the problem but its all the same nothing changed I can use ubuntu but not windows. Can someone please tell me how I can solve this. Thanks. http://paste.ubuntu.com/1231432/ (HowTos)
