[Bug 633983] Re: Can't boot amd64 live cd on Mac (EFI)

[Samuel Iglesias]

When booting the operating system will not recognize the presence of the
LiveCD, and you will end up with a console of initram.

I followed one tip found on Internet.

* Create an USB with the image of Ubuntu 11.10 x86_64 following the instructions on http://www.ubuntu.com/download/ubuntu/download  
* Then burn a CD with the same image.
* Plug the USB and insert the CD.
* With rEFIt boot from the CD.
* When booting, the CD will be "lost" but it will continue with the USB image.

Now, I have Ubuntu 11.10 on my macbook pro 8,1.

Bug description:
  Previous release livecd's were bootable by holding down option while
  the cd was in the drive and selecting the "Windows" cd.

  Trying this with the Meerkat beta desktop livecd image (md5sum verified) I just get two numbers (1. and 2.) which look like
  they should be labeling some text but there is no text visible and the message to select CD-ROM boot type.  Typing either a 1 or a 2 doesn't do anything.

  Googling revealed that some Windows beta iso images had the same problem booting on Macs; apparently in this case it was an issue that the Windows version had EFI support (and so didn't use the BIOS fallback) but was assuming a newer version of EFI.
  There were some other posts which claimed that it was that the iso image was generated incorrectly (something having to do with ISO9660 versions).

  Unfortunately, even though I develop software for a living, there is
  nothing I can do to help debug this (except try newer versions) since
  once I get to that message, everything seems unresponsive.

  The upshot is that a useful thing which I did frequently in older
  versions (i.e. boot the 64bit desktop livecd on this macbook) no
  longer works.
