View Full Version : [ubuntu] MacBook Pro 5,1 (broken optical drive) fails to boot from USB

August 1st, 2012, 05:15 PM
I have a MacBook Pro 5,1 and I am trying to install Ubuntu 11.04 Natty (or, in fact, any Linux distro at all)

I haven't done any kind of partitioning, I don't want to use MacOS any more, so a single boot Ubuntu or multi-boot with different Linux distros is basically what I'm after.

I used UNetbootin to transfer an .img to a FAT 32 usb drive, but it failed to boot.

I followed the ubuntu 'create a USB stick on Mac OS X (http://www.ubuntu.com/download/help/create-a-usb-stick-on-mac-osx)' thread - when trying to boot from the usb drive, it did not show up.

This technique (http://studyblast.wordpress.com/2011/08/14/guide-mac-os-x-lion-how-to-boot-a-linux-live-system-from-a-usb-drive-how-to-update-any-ocz-ssds-firmware/) (using iso-2-usb efi-booter for mac 0.01) got me closer, I got a message with 'loading Linux, loading RAM, fasten your seatbelts while we load the kernel'. it then froze.

I repeated the technique using different .isos - one was a method using a minimal CD download (http://www.joop.in/Archive/multibooting-osx-lion-ubuntu-linux-on-macbook-41-without-cd/), it got me to grub, but I didn't know how to progress further, and my much-more-linux-literate friend who was helping me was unable to improve the situation.
I've tried with a 1386.iso, and fedora too, but still no luck.

any suggestions?

Lets start from the beginning.

Your computer is more than capable of running the latest version of ubuntu so download the .iso and use unetbootin (http://unetbootin.sourceforge.net/) to create the live USB.

When you are rebooting hold down C

Select the USB to boot from and tell me what happens then.

p, li { white-space: pre-wrap; } Once UNetBootin has created the USB, I get the following:
"The created USB device will not boot off a Mac. Insert it into a PC, and select the USB boot option in the BIOS boot menu."

I hold down C, it comes to the refit page, select 'boot linux from USB'.
The screen goes black, then I get a message 'Boot Error_"

the other option at the rEFIt page is boot from efi/boot.

This gets me a screen with three options:
-Try Ubuntu without installing
-Install Ubuntu
-Check disk for errors

All of these result in black screens.
