Recover Windows Partition in BootCamp

Hi!

I tried to look for a solution for my problem, but I couldn't solve it. I hope I can have some help of you guys.

(sorry for my english)

My problem is similar to the discussion bellow:

I have a Macbook Air mid 2012, I set up BootCamp before, like one year ago, to run OS X El Capitan v. 10.11.16 (170GB) and Windows 10 (80GB).

So everything was OK. I have to use Windows often because of my work applications, and I could use very well until I run out of my space in my hard disk on Windows. So I decided to resize my partition for 130GB to Mac and 120GB to Windows. In that time, it worked perfectly. I've used Mac Disk Utility to decrease Mac Partition and then in Windows, I've used tool MiniTool Partition Wizard to increase the Windows Partition.

I could use in that way for more than 6 months. And then, run out of my space in hard disk again! (Even using external drives, my project need to be in the partition)

I thought, if I could do it before, I can do it now. Yesterday, I used Disk Utility to resize my partition to 110GB (MAC) and 140GB to Windows. I logged in my Mac OS and resized the partition. After reboot the system, the Windows Boot is no longer in the options when I start my machine using Alt Option button.

What I've tried:

- I have tried some commands in terminal following that discussion but nothing happened, when I used the command to write in MBR, it says Operation not permitted;

- I have tried to repair windows partition disk utility in recovery mode and it showed a message: Invalid BS_jmpBoot in boot block;

- I have install Paragon NTFS for Mac to repair the partition and same error message showed:

- I saw in some discussion that Mac can only support 4 partitions, so I deleted the partition that I created before (20GB).

My Disk Utility is like this now:

- The third option on Boot Camp Assist, Install or Remove Windows 7 or later version is greyed out.

- I've never really used command line before but I think that this information might be helpful:

- And bellow are the command I tried following the discussion as well:

I don't know what else I can do. I'm starting to get desperate.

Please, If anyone can help me I would be glad.

Thank you!
