Hello! I've just tried to install Windows 10 on my Macbook with a 32GB USB using Bootcamp. Everything was fine until I came to the part where I need to pick the partition where I want to install my Windows 10 and of course I've picked the Bootcamp partition but actually I couldn't click on "next" (I was so dumb and didn't formate it). So I just formatted the Bootcamp partition and when I tried to click on "next" it just told me "We couldn't create a new partition or locate an existing one". I went through google and searched everything about this problem and there are a lot of guys having almost the same or exactly the same "error" when trying to install Windows 10 on the Bootcamp partition but nothing actually helped me. I've already removed everything except my USB and someone told me I should only have 4 or less partitions. It shows me 4 partition but there are two partition (3) and two partition (1). Is that a problem? Here's a pic of my diskutil list: https://i.gyazo.com/f554fb8aac609c2420f55f9696fa06a6.png Since english isn't my native language I'm sorry for my bad spelling. I hope anyone may help me installing Windows 10 with Bootcamp! Thanks a lot!
