How to repair bootcamp after messing up with partitions?

Hello there. I have a Macbook Pro Retina 15', I've created a new partition for the Yosemite but I didn't know it would mess up with my Boot Camp.


First I had this issue: (No bootable device --- insert boot disk and press any key) so I just used my bootable flash drive and try to repair the windows, of course its failed and starting showing up a new message error: "An error occurred while attempting to read the boot config data"


Then I follow the instructions on the first post: https://discussions.apple.com/thread/4144252?start=0&tstart=0


But the windows keeping showing the same error (An error occurred while attempting to read the boot config data).


I don't have Yosemite partition anymore, but I have a hole and can't resize it anymore:

I don't have external optical drive and don't have any FireWire/Thunderbolt (I even don't know where I can buy).


I think it's more easy to clean up my bootcamp and starts again from the beginning, since I have access to Bootcamp Partition I can copy my files without problems.


And yes, my USB flash drive was the original Bootcamp Boot Assistant (windows installation). I tried to make an Windows Recovery (the same as the DVD that windows create for me) but it doesn't work either.
