I want to install Win10 in a partition on my Macbook Pro.
Model: Macbook Pro 13' MID 2010.
I already have Windows Software Support that I downloaded from Boot Camp app.
To do so, I created a partition with 140Gb with I called "BOOTCAMP".
I need to change this partition to GPT so, to do so, I downloaded GPT fdisk.
After I installed it I opened "terminal" and run the command
sudo gdisk /dev/disk0
I got this:
Warning: Devices opened with shared lock will not have their partition table automatically reloaded! NOTE: Write test failed with error number 1. It will be impossible to save changes to this disk's partition table! You may need to deactivate System Integrity Protection to use this program. See https://www.quora.com/How-do-I-turn-off-the-rootless-in-OS-X-El-Capitan-10-11 for more information.

About to write GPT data. THIS WILL OVERWRITE EXISTING PARTITIONS!!
It is in Portuguese but I think you can understand the important things.
So, my question is: If I give it a "Y" in terminal, will it overwrite both of my partitions or only the partition called "BOOTCAMP"? (Will it erase my main partition?)
