I don't understand how a live image relates to this topic. The OP wants to install debian alongside MacOS, so he needs a standard image. I recently installed debian stretch on my MacBookPro12,1, using a netinst image that included non-free firmware (needed for my wifi adapter). I flashed that image on a USB stick, as 12,1 does not have a DVD drive, but it would be the same on a DVD-ROM. I can say that the installation worked well.

The standard installation iso files do. If the efi installer fires up it will apparently identify itself as such when it does so. If you boot the Mac and choose option C in the start up mode that is supposed to try to boot up DVD iso files etc but the article suggests this could fail if the efi driver isn't loaded - the rEFInd utility solves this problem it seems. Apparently you need to convert the iso file into an image format. It's probably easier to install Debian on an IBM 390. Cheers MF
Re: Help Installing a Dual Boot Debian and Mac OS MacBook Pro 9,1
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.

The point is that, in contrast to all other PCs I had, on Macs you cannot enter the BIOS setup and configure the boot order. You have to press the "Option ⌥" key while powering on the Mac. That will allow you to enter the Startup Manager, where you'll see a list of all bootable devices available, and choose the one you need (e.g. a bootable DVD-ROM).

I would suggest a couple of things. When you say that the DVD does not seem to be recognised when you boot up the computer, I am assuming that you mean that the bios is not attempting to read the DVD and boot from it. If that this the case then you need to play with the bios on your Mac box to get it to boot from the debian DVD. If you google around and seek out some bios booting instructions for your Mac machine and experiment with it you will be able to persuade it to go for the DVD first - before the hard drive (s) etc and boot from it. Once you get this to work I would suggest you try booting from a Debian Live CD. Then post up how you got on here on the site and suggestions on installing the OS can be made from the vantage point of running a few diagnostic commands concerning your disk partitions etc that would likely be suggested by people on this list.

Sorry, the right key you should press to get that Startup Manager is "Option ⌥"--not "Command ⌘" as I previously wrote. https://support.apple.com/en-us/HT201255

Have you tried to press the "Command ⌘" key while turning on the MacBook with the power button? A screen offering different boot options (e.g. MacOS on disk, debian installer on DVD) should be displayed.

Just create a partition for that purpose, put a filesystem on it, and set up both systems to mount / access it when they are up. If the other system is Windows, you probably want to make it something like a FAT-32 filesystem.

Don't do it. I had nothing but fits with dual boots. Instead load Oracles Virtual Box (open source), learn how to set it up and then install Debian on that. If you don't like it, un-install Virtual Box and everything goes Poof. In addition, you don't have to worry about a grub loader and other such esoteric things. There is absolutely no interaction between the two OS's. One thing. You will have to set up a file folder that is shared between the VB OS and your regular OS. It allows file transfer between the two systems. Try that with a regular dual boot setup! Good luck Gary R.
Re: Help Installing a Dual Boot Debian and Mac OS MacBook Pro 9,1
Hi, Rafael Lauda qrote: > I have installed the iso image for Debian 8.7.1 1 onto a DVD-R. How exactly did you do this ? (What program did you use, which options therein, any peculiarities ?) >From which URL did you get the ISO ? > I have installed rEFInd [...] > When the computer is turned on the dvd does not show. I understand from http://www.rodsbooks.com/refind/using.html http://www.rodsbooks.com/refind/features.html http://www.rodsbooks.com/refind/configfile.html that the DVD will show up if there is a file *.efi underneath the /EFI directory of a recognized filesystem. Well, if it is overly smart by looking into the ISO 9660 filesystem and not smart enough to follow the El Torito boot catalog entry to the FAT filesystem in /boot/grub/efi.img, then there is no boot loader detected. Suspiciously, the wiki page https://wiki.debian.org/MacBook#Installing_rEFInd describes installation of rEFInd _after_ installing Debian from ISO. > I’m not the most tech savvy Then be cautious with my next request. Don't do it if in doubt: Can you put the ISO plainly onto an USB stick and try to boot from that one ? See https://www.debian.org/CD/faq/#write-usb "Please note, that Debian advises not using "unetbootin" for this task." The danger is that you could use the wrong /dev/sd address and thus overwrite the wrong disk device. So get an overview of disks while the USB stick is _not_ connected: ls /dev/sd? and then again when the USB stick is plugged in. There should appear a further /dev/sd-something name. E.g.: /dev/sdc Make sure by reading 100 MB from it and checking whether the USB stick blinks: dev=/dev/sdc sudo dd if="$dev" bs=1M count=100 of=/dev/null Only if you are sure to have the right address the ISO to it sudo dd if=debian-8.7.0-amd64-DVD-1.iso of="$dev" bs=4M ; sync if= path to input file (harmless) of= path output file (dangerous) bs= block size (moderately large for best speed) count= copy size restriction (only in the test read run) Have a nice day :) Thomas
