Hello,
I pocess a macbook pro retina with El Capitan fully updated.
I want to add a Windows 10 on it with Bootcamp.
BCA helped me to create an USB installation for Windows 10, but it can’t partition my disk to install windows 10 : each time I try I have message error : Disk Could Not Be Partitioned, Error On Boot Camp Assistant.
I tried to re-start on Single User Mode, but when I turn it on and immediately hold down Command + S, it still start as usual, does the trick work with OS x El Capitan ?
Thank you for your help,
