I have installed fedora15 on my linux laptop fewdays back, while installing I removed the backup drive of windows and installed it fedora-15. After installing fedora I have problem using my Windows-7. Whenever I try to boot my windows it is asking for repair.

I afraid to GO for repair, because I feel it might corrupt my fedora-15. below is the output of my fdisk. CAn I try to restore windows or not?

Code:
# fdisk -l
