Is it not possible at all to install Ubuntu just with a live CD? Do I need to install it with a live USB?
At first hand I installed rEFIt which enables to see the ubuntu live CD but when chosen to boot from it, just black screen with blinking cursor. Fn+F6 did nothing for me. Saw on some documentations installing refind and changing screen configurations on macHD.
Well, the screen configs have to be built from start, is that it? None of the documents for screen boot in EFI already exists on mac system, so I need to create it from scratch, is that really it?
I’ve downloaded isos - 12.04 amd64, 12.10 amd64 and 13.04 i386. See the point here is, latest macbook pro versions are intel based, so I’m in doubt if amd64 is really the best iso for it. Just to mention, none of the three above downloaded boots to a grub or to a install “Try Ubuntu” screen. All 3 just boots to a black screen with blinking cursor and after a while, just black screen, again, hitting C or Option-Alt or Fn+F6 did nothing.
For starters, to see which model i had, none of the documentation where true. the steps that worked out for me were
sudo su admin pass sysctl hw.model
that gave me the answer: macbookpro9,2
In my “about this mac” the answer is 10.8.3, 13-inch, Mid 2012, Processor 2.5 GHz Intel Core i5, Memory 4 GB 1600 MHz DDR3, Graphics Intel HD Graphics 4000 512 MB, Software OS X 10.8.3 (12D78).
Thanks for the patience. Building a document in portuguese compiling the research, can be seen here https://docs.google.com/document/d/15237Vio3_DRnecg-WuJm-Oz_y5rFMKXGN00G_2uUSUU/edit
Just for stating, partitions are like this right now
