First of all, I have a Macbook Pro mid 2009 with Intel Core 2 duo running OS X Yosemite (8Gb of ram, 500Gb SSD), I downloaded ubuntu-14.04.1-desktop-amd64.iso and I use a 4Gb USB stick

Here is what I'm trying to do: As I have an issue with a hard drive (EXT format) from a Synology NAS, I'm trying to access this hard drive using Ubuntu as mentioned on the Synology FAQ: https://www.synology.com/en-us/knowledgebase/faq/579).

Here is what I did: To create a bootable USB stick, I followed the insctructions from ubuntu.com: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-mac-osx using the ubuntu-14.04.1-desktop-amd64.iso.

Here is the issue: When I start my mac and press alt key to show bootable menu, I see two EFI-boot options on the USB stick (I don't know why). For both, when I press Enter I have the error message "could not open "\EFI\BOOT\fallback.efi": 14" then I have the screen which invites to try ubuntu or to install it. In my case, I just want to try it, so I choose "Try ubuntu without installation" and press Enter. Here happens the black screen.

I don't know how to fix it but help would be really appreciate 'cause I'm trying to retrieve some datas on my hard drive.

Thanks

EDIT: I also tried "install" mode instead of "try" mode -> same behavior. I also tried using ubuntu-14.10-desktop-amd64.iso -> for both modes, "install" or "try", I get the error "i8042 no controller found" and screen freezes...

EDIT 2: I also tried external hard drive instead of USB stick -> same behaviors

CLOSED: I decided to close this post 'cause finally, using Live DVD of Ubuntu and rEFInd, I succeed the installation.

This is not a fix for the issue but an alternative.

I decided to use a Live DVD and rEFind according to this tutorial: Freya on a Mac

As the rEFInd version used in the tutorial is older than the one I used (v0.8.3 vs. v0.8.4), some steps changed. Here are changes I applicated:

  • Step 4: I only type ./install.sh --alldrivers 'cause --esp is no more available in v0.8.4 (source)
  • Steps 6 and 7: I only skip those steps 'cause v0.8.4 do the job for you
  • Step 14: I make sure to create 2 partitions: one in ext4 format (other dropdown: select "/") and a second in swap "format" (swap partition must be between 1x to 1.5x your RAM)

Since the second boot on Ubuntu from the rEFInd screen, each time I choose Ubuntu, the load freezes. To fix this issue, I press F2 when I select Ubuntu, then I press again F2 to edit the launch command and I add nomodeset at this end of the command.
