Do you want to proceed? (Y/N): y

OK; writing new GUID partition table (GPT) to /dev/disk2.

Warning: The kernel may continue to use old or deleted partitions.

You should reboot or remove the drive.

I didnt know, I just followed the guide. The 120GB disk is the mac mini drive

The 8gb is a flash drive

the 240gb disk is where the problem is. The 190gb is the osx partition and the 50gb is windows

The 1tb is an external HDD

I got my ssd named Macintosh SSD, only option there but i booted right into osx. Thanks so much! You're a life saver.

Also do you know any fan control software that will work in windows on the macbook? I tried speed fan but it doesnt work.

It showed up in disk util but not in the boot menu. I really dont care as I needed more space anyways and Im just gonna delete the partition and remake a bootcamp partition. Way less of a pain that the 10 hour mess i created before

I already have it installed

It says that there is a protective MBR and a damaged GPT when I do the sudo gdisk /dev/disk2

I also got a "no room for the GPT header when trying the

gpt create -f /dev/disk2
