Q: Bootcamp with Win' 8 won't start after Yosemite

After installing bootcamp I had to upgrade my windows partition, it worked until I upgraded to Yosemite.

After upgrading and rebooting and clicking alt the windows option didn't even appear.

I tried a couple of tips in the communitie threads and managed to get windows to appear as an option on reboot however I get the message

"missing operating system".

 

Following Loner T's suggestions I get these results:
