I am trying to dual-boot os x 1.11 ('el capitan') and elementary 0.4 (loki).

I hit option to get to the boot menu and get the disk select screen, but when I get into GRUB and select 'try elementary os without installing', I am getting a quick of flash of 'Can not find /boot' and then a black screen forever. This is on a late 2011 macbook pro. Any advices?

The "Can not find /boot" is rather odd, I suggest following a tutorial in details to install rEFInd and create your bootable usb device.

As for the black screen, this is a kown issue with the MBP and the AMD graphics card, which you'll need to disable.

The last link provided by Peter Uithoven (Update #9) here will help. Black screen when installing OS

  • Any recommendations for a good rEFInd tutorial?
