I am a complete novice when it comes to macs. I recently tried to use bootcamp to run windows 10 and partition part of my hard drive. I used the bootcamp assistant and I followed all of the steps but when It came to the formatting bit whilst installing windows somehow it went tits up. Now I can't re-do bootcamp because of all of these partitions. i have tried disk utility but to no avail the '-' is always greyed out and I can't resize them using the partition pie chart. I have trawled the internet for days now trying to figure out a way to put them all back into a single partition to retry the whole bootcamp procedure. Its a 2015 27" 5k mac. It is is literally driving me insane.
I did go into diskutil in terminal but I couldn't workout how to copy and paste the text from that into here!!!
Any help would be appreciated massively.
