Can't mount bootcamp partition in 10.9.5

Question

Hi, I'm only able to boot into my bootcamp partition by restarting the computer and holding down alt/option. When I'm in OSX, I'm only able to see the partition in Disk Utility, and it's greyed out there. I just installed Windows 8, updated to windows 8.1, and then installed a mavericks update. I guess somewhere along the line the bootcamp partition got disconnected from mavericks?
I did some googling and I think I need to do something in gdisk to fix it, but I'm not sure how that works. Here's my output from
sudo fdisk /dev/rdisk0

and from sudo gpt -r -vv show /dev/rdisk0

gpt show: /dev/rdisk0: Pri GPT at sector 1
gpt show: error: bogus map

Any help would be appreciated! I already installed gdisk successfully, just have no idea how to use it.

Answer 1

Yeah, and actually I tried using gdisk because I hadn't gotten any replies, I really messed up what I had and now I can't boot into windows ^^;
Here's a new version of those previous two. Somehow BOOTCAMP turned into XENIX, I have no idea how or what that means (nothing good probably)

And here's some other stuff that might be helpful
