I have tried multiple times to install Ubuntu 16.04 LTS on my Mac Book Pro 2011 with a TakeMS SSD and a Hitachi HDD.
The problem is though that it copies files fine, but as soon as it gets to GRUB, the installer fails and crashes. This has meant I had to go into GParted and clean the drive.
I am installing the Whole system and Boot loader on the SSD and I think this is a bug.
