Returning Partition Table

Hi all,

it looks like this is the best place to ask a question on partitioning. I'm not that experience on this front hence getting myself into this pickle.

I used to have the standard MBR bootcamp partition, with Windows and OSX, also had rEFInd setup nicely for boot options, but wanted to slightly expand the Windows partition. I booted in recovery mode, used disk utility to shrink the OSX partition, this is when I found out that I wouldn't simply be able to boot restart the laptop and expand the Windows partition into the now free space. I finally managed to follow a guide that helped me fix the issue by rebuilding the partition table, for the current state of the volume, but I would like to just return it to my previous clean setup.

So I'd like to re-expand my OSX partition back to how it was and restore the previous partition table with EFI.

Could someone please instruct me on how to do this. I know I'll have to expand the OSX partition which will cause it to break again, but instructions from that point onwards would be really appreciated.

The output from "sudo gdisk /dev/disk0" is:

MBR: hybrid

BSD: not present

APM: not present

GPT: present

The output from "diskutil list" is:

/dev/disk0 (internal, physical):

Thanks so much for your help in advance,
