It may be fixable by running the Windows automatic repair feature from a Windows installer. It may need running 3 times as there could be 3 things to fix.
I appreciate that you don't have one whilst travelling but it may be an option once you're back home.
Can you access the Windows partition and its files from within OSX?
Could you please give the output from the following terminal commands in OSX?
sudo gpt -r -vv show disk0
sudo fdisk /dev/disk0
Those assume that you have only one hard drive in your Mac (disk0).
Hi

thank you for your reply
If you mean can I access the files from the Finder then yes I can do that
and these are what came up when I typed in those commands:
