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.

the problem is, that apple efi is not compatible with windows uefi, so will get this error on some mac models with 64bit vistaa sp1, 64bit win7 and now with ubuntu too. the only way to fix this with windows is to create a new install dvd without efi, hopefully the ubuntu devs do not remove efi but try to support apple efi, if this can be done. otherwise please make the livecd not to boot efi on unsupported machines.

Hi Kalman,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 633983

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

The keyboard becomes unresponsive here and I can't go any further.
The third option says that it can't find a proper EFI image and offers to go back to rEFIt.

I don't think it is a bug with Linux - it's probably IsoLinux.

Booting from 64-bit Live CD works in Lucid. This might be related to the fact that Maverick uses syslinux 4.x while Lucid and earlier releases use syslinux 3.x.

Andy Whitcroft (apw) wrote : Re: Can't boot Maverick beta amd64 live cd on macbook (EFI)

It is not clear that this is a kernel issue. It is likely this is a incompatibility between the Mac EFI and i386 uEFI implementations. This is suggested by the fact the i386 images boot correctly (which do not have EFI support) but the amd64 images do not (which do have EFI support). To confirm that this is the cause of the issue I have remastered the amd64 image without the EFI support. If those who have these machines could test the image below and let us know it works for you:

Hi, probably a tiny bit too late, but did you try out a (very) recent grub version? I for myself was persecuted by the boot problem starting with amd64 releases of ubuntu 9.xy on my MacBook3,1. Until today I ran a custom grub 1.96 setup on my EFI partition (I expect 1.98 to behave the same). I decided to give its bzr live development branch a try [1] and it fixes the broken ramdisk loading for me (I am now able to boot an official ubuntu kernel instead of the vanilla non-initrd workarounds I was used to). Only problem seems to be the working of video=efifb. Screen got blank somwhere in between booting (I'd guess when encountering conflict between efifb and intel(drm)fb [2]) and stayed blank, but luckily the gdm-startup sound/input sound was hearable. So I did a blank login (no change) and then did close/open the lid and trigger a sleep/wakeup cycle, which amazingly brought up the running X session, I'm writing from. Maybe I should just use video=inteldrmfb instead of video=efifb as boot parameter, though my vanilla kernel with video=efifb (and without inteldrmfb support) didn't show the blank screen issue.

I have a March 2009 version of the Mac Mini. I've been a happy customer of 10.04 64 desktop. Today I tried booting ubuntu-10.10-desktop-amd64 live CD, holding down the <option> key while powering up. The choose-OS screen shows two options for the CD, one labeled 'Windows' and the other EFI. If I select the EFI choice and further choose to launch the live CD instead of install or check disk, then I get exactly what satmandu wrote on 2010-09-27 above. But the alternate 'Windows' choice seems to work fine.

So what was the 'fix' that Robbie Williamson mentioned on 2010-10-09? I'm guessing the inclusion of the second choice that appears labeled 'Windows' (which was the only choice available with the 10.04 live CD). And where might I go online to follow the progress of mac EFI support?

Though not directly concerning this bug, I'd like to ask if anyone experienced PRAM corruption or other strange problems while trying the desktop amd64 installer.

I was able to render my MacBook 5,1 unbootable two times yesterday when I tried the standard (non-"+mac") iso. Neither Snow Leopard would boot nor any Apple installation media I had at hand, nor Ubuntu 10.04. OS X told me it could not enumerate a USB device in some port (none were connected) and then hung up with "still waiting for root device".

After zapping the PRAM, all installations worked again, and I could also boot the Snow Leopard installer DVD. After fiddling around some more with the amd64 installer, the same state occured, after which I had to zap the PRAM again.

Has anybody seen something similar? If not then maybe I need to get my logic board checked or replaced, if this continues.

I'll try the "amd64+mac" installer now.

This was the closest bug I could find to an issue I have been having with maverick built kernels and efi. some background first:

I have been building kernels on a linuxmint 9 (lucid) based system, for a joggler device target (efi based device - see http://en.wikipedia.org/wiki/O2_Joggler).

The bug:

Everything was working fine, until I upgraded my system to the linuxmint 10 RC (maverick based). I understand these are not specifically ubuntu, but the build and base system is the same.

After I had upgraded my kernel building machine to linuxmint 10 RC (Maverick based), my kernels have failed to boot on my efi based device with a failure mentioned earlier here "RAMDISK: couldn't find valid RAM disk image starting at 0." the initrd is loaded, but then this failure has occurred. I spent some 7+ hours thinking I had made some error somewhere, and modifying my kernel options, yet even using the config from a previous kernel which worked fine, it would always fail to use the initrd.

Having worked thought every possible "human error" cause I could think of, I could only fall back on the differences between the old and new system. For example GCC/binutils etc. I had already tried a few versions of GCC and it didn't seem to help.

I have however solved the issue now, and it points to an issue with the maverick binutils. After my many failures I downgraded binutils to the lucid release, and rebuild the kernel as usual. It worked!. to make sure it wasn't some fluke, i then upgraded binutils again to the maverick release and rebuilt. again the same failure.

I have no idea what would be causing this specifically with for example LD or some other part of binutils, but I am completely unable to build a kernel that will work with an initrd with the maverick binutils. downgrading them to the lucid version solves the problem completely. This points to what I think may be some significant problem with the maverick binutils, however due to my test case, it is hard to debug further.

I can confirm there is a *Binutils* issue with building kernels on Maverick, which results in boot failures on (at least my) *32-bit* x86 laptop (not a Mac). The symptoms are different to those described here, but consistent. It suggests a miscompilation/mislinking.

When building on Maverick, I get a kernel which doesn't boot.

When building on the same system, with the same kernel source and config, with just GCC downgraded to Lucid's version, boot fails in the same way. When Binutils is also downgraded, the kernel boots - and the symbol map is at last identical to the kernel I built before upgrading Lucid to Maverick.

I mention this here because an earlier comment refers to Binutils.
Perhaps this entire bug is due to the Binutils issue?

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.

The amd64+mac iso images of Ubuntu 11.10 and 12.04 alpha are both working for me.
But it looks like a workaround, not a real fix to the standard amd64 iso image.

It appears that there are no longer any +mac images for 12.04 that I can see (been rooting around releases.ubuntu.com). Has anyone found any images? I attempted to create the image myself via the red hat link but it was fruitless.

@brettcornwall: there are +mac images, just not on that server. Yes, it's kind of dumb to have them spread out, not in the same place...

I just tested an Ivy Bridge Macbook with the latest trusty daily amd64 image (written to USB stick with dd):

1. boot from apple manager works
2. boot from refind (efi) works
3. boot from refind (bios) works

So it appears this bug is fixed, the amd64+mac images are no longer necessary, at least on this particular hardware.

Please also comment in bug #1298894 if you *can* boot the regular 14.04 / trusty amd64 iso on your Mac. There is no point in continuing to produce a Mac specific amd64 image if the regular one now works fine, but it will not be possible to tell if this is the case until people try it and report back.

I believe for that old Mac you do need amd64+mac ISO image of Ubuntu.
Note that these are no longer produced. Alternatively, to install
without UEFI you do need to invoke legacy boot (bootcamp/windows)
procedure to install amd64 image using PC-BIOS emulation.
