Re: Help Installing a Dual Boot Debian and Mac OS MacBook Pro 9,1

[Cathy Gramze <rhiamom@gmail.com>]

As an iMac owner who has had a dual boot Mac system before:

Hold down the C key while the computer is starting up, and the computer 
will boot to the DVD. (assuming the dvd was burned correctly as a 
bootable DVD)

reFind is a very nice app, but unnecessary, and *really* mucks up being 
able to completely remove one of the boot options from the computer 
should you want to remove it later. I also found that setting up a dual 
boot system made my iMac boot much more slowly no matter which system I 
selected. This slowness persisted after I returned to a single boot 
system. YMMV.

I wish you luck, and hope you like Debian.

I have installed rEFInd on my MacBook Pro, and I have installed the iso image for Debian 8.7.1 1 onto a DVD-R. When the computer is turned on the dvd does not show. I had also partitioned space on the hard drive as well. I don’t want to settle for another Distro, I want to install Debian as I feel it is the best Distro currently using the Linux kernel. I’m not the most tech savvy but I have been putting the effort into becoming more computer literate. Any and all help would be greatly appreciated. Thank you in advance for making a wonderful Distro and with any help you may have for me.
