Repairing Bootcamp partision after creating new partision

Hello. I tried to create and additional EFI partition on SSD to transfer files between my Bootcamp and Mac Partision on my mid-2012 macbook pro. I realized afterwards that I should have used bootcamp assistant to create that additional partition and now cannot boot into bootcamp. I deleted the extra partision without thinking and may have complicated the issue. Bootcamp is still visible and accessible from finder and the startup disk. Also my macbook has two internal drives, but the SSD with the operating systems is disk0. And windows and the mac side were both working perfectly before I gaffed.

I tried Loner T's GPT Fdisk's fix and have run into an error on the last state

stating "unable to open device '/dev/disk0' for writing! Ernno is 1! Aborting write!"

These are the steps I took below:

sudo gdisk /dev/disk0

r (revovery and transformation menu)

h (create a new hybrid MBR)

4 (add partition 4 to the hybrid)

enter(excepted the default mbr hex code of 07)

y ( set the bootable flag)

n (do not protect more partisions)

0 (print)

w (write)

then I run into the error.

Anyone have any ideas? I've included more info below
