After changing my mac partition, bootcamp can't find windows anymore! searching for Loner T (haha)

Hello,

I am running windows 10 on my iMac and now my bootcamp partition got full. So i tried to resize my bootcamp partition but i couldn't do so with disk utility. I tried to shrink my mac partition and made a new unnamed partition in the hope i could reassign this unassigned space to my bootcamp partition. This also didn't work so i gave up hope and deleted the unnamed partition and tried to reboot my mac with windows. Only now i have the problem that my mac won't boot my windows partition anymore and gives me the error: "No bootable device -- insert boot disk and press any key".

After searching the web i came across a post here called: "After changing my mac partition, bootcamp can't find windows anymore!", the person in the post has the same problem i have. I am a bit scared of trying to fix this by myself without some professional guidance. (my windows 10 partition has 250gb of data i don't want to lose). Some of the outputs i get from the terminal commands are also a bit different then the original post.

So now im hoping Loner T will read this post and hope that he can help me out with the Terminal commands. And maybe help me with making my bootcamp partition bigger.

I am running on a IMAC late 2012:

Bootcamp windows 10

Osx EL Capitan version 10.11.3 (15D21)

Output from: diskutil list:

Output from: sudo fdisk /dev/disk0

Output from: sudo gpt -vv -r show /dev/disk0

Output from Testdisk (don't know what i should select here, from here i need help):
