Repairing bootcamp after creating partition in Macbook Pro 13" Mid-2012
Hi All,
I have made a mistake like few other users and created a FAT-partition to resize my bootcamp partition space.
After this I am not able to boot into Windows (Bootcamp) anymore. I can see it when choosing the default start up system in OS X but I can not choosing it after restart with ALT-key pressed.
I've read some threads about the exact same problem, but as every user was ask to post a new problem,
I'm doing so now and hoping that there will be someone who will help me out in this situation.
I've even tried executing few procedures mentioned in the old threads but it didn't worked well in last few steps.
My system:
MacBook Pro 13" mid 2012
OS X Sierra 10.12.3
(Windows 10 on Bootcamp)
Below I attach the output of various commands mentioned in other threads:
