Ubuntu / Apple :: Cannot Boot From Cd For Install?
Jan 29, 2010
I am trying to put ubuntu an old imac with osx that a former customer gave me. I am not extremely well versed in Apple products but have been doing research intoy current problem. I have tried just putting in the ubuntu shipit disc I have, along with downloading and burning 9.10 text based and have not been able to get it to install. I have tried holding 'c' when rebooting, holding 'option' while rebooting it only gives me the choice of booting from osx), and holding 'control, option, apple, delete' as well to no avail. I then tried downloading Virtualbox and mounting the dmg and found out that my imac is not letting me mount any dmg's at all. Any guidance? Can I take out the harddrive and hook it as a slave to my pc and somehow install ubuntu that way and put it back in the imac? All I want is for the imac to be useful again as I was trying to make it into a stand alone dvd player.

Toward the end of installing Ubuntu 10.10 32bit (Alt CD) on my iMac 11,1, the installer asked me to type in the location for installing the grub boot loader.
I told it to use /dev/sda3 and it immediately failed. I'm still in the installer. Can anyone suggest a solution?
Here are my partitions on sda:
...from the shell in the installer, there is no grub.cfg in /target/boot/grub.

Model:MacBookPro1,1
Intel Core Duo 2,16 GHz (32 bit)
OS X 10.6.2
Boot ROM-version: MBP11.0055.B08
SMC-version (system):1.2f10
2 gb ram
I've tried this guide: [URL] to USB Stick
with both the standard 9.10 32 bit cd and the netbook remix. when I try to boot and hold alt the only partition that appears is the os x one. so no usb.
the cd reader is broke. that's why I'm trying via usb.
edit: its a usb stick btw, 16 GB that I'm trying to boot from.

I installed Lucid PPC on a G4 iMac (lamp-style, 800 mhz) using the netinstall mini cd. The install environment booted and installed a base system without any problems. However, when trying to boot into the installed system, I get about a second of text after the yaboot screen, then darkness, then a full screen of bright red. Note that X is not installed, so the red screen is not an xorg problem. I've tried booting with "Linux nosplash video=ofonly", and "Linux single" but the problem occurs in both cases. I can use rescue mode on the cd and chroot into my system on the hard drive, but I'm not sure what steps to take from that point. It does seem to be a functional system when I'm chrooted, I can use apt etc.I don't want to give up on this installation and install karmic yet,

Having successfully installed kubuntu 10.04 on my Powermac G5 I was wondering if I can install os x and dual boot, there are plenty of tutorials around but all of them involve installing kubuntu on a system with os x already installed. If there is any danger of damaging Kubuntu then I will leave it as I really don't want to go through the hell of getting it working properly again! Also I have plenty of hard drives kicking about - would it be safer/easier to install os x on it's own hard drive? And if so how would things work with yaboot?

I modified SnowLeopard to install on mbr disk format. How can I chainload to the bootloader on the OS X partition using GRUB2. The autodetected entry MAC OS X put in by ubiquity on installing ubuntu doesn't work. In grub legacy I just added an entry with root() and chainload and it worked. How can I achieve this with grub2?The computer is an Intel Mac. I am unable to install Windows 7 on a GUID disk (without using bootcamp).

I did a full install of Ubuntu on my MacBook Pro (7,1) and I am trying to boot into the OS X disc but the screen always pulls up the Apple logo and loading circle and then greys out and tells me to turn the machine off.
I cannot get into disc utility or anything. It almost seems like the computer doesn't know how to handle the disc. I did not use Refit and the only change I made to the boot loader was blessing the ubuntu partition.

I have installed Ubuntu 10.10 as the only OS on my Macbook 2,1's entire hard drive (used Live CD to reformat and install). Now I am wondering if it is possible to add a partition and install Mac OS X Snow Leopard alongside Ubuntu, for dual boot purposes. I have seen a lot of documentation for doing this the other way around--adding a Ubuntu partition to an existing Mac OS X installation, but I haven't found an answer for adding OSX to existing Ubuntu. If anyone knows anything about this

I have 11.1 installed on an old G3 system. The PowerPC config has worked well, but after an update I get a black screen at GDM. I think all is well, but the resolution/refresh rate is set too high.How can I get in to change to runlevel, access SAX2 or change the GDM/Gnome resolution settings?I think I've been able to blindly login

This seems to be a variant of a problem many people have had, but after several hours trawling through various forums, I haven't seen a reliable match for my situation.In brief:Adding a third boot partition (of Ubuntu) to my existing dual boot of OSX 10.6 and Windows 7 seems to have crippled the Windows boot from working, because Grub apparently takes over the process. Yet Grub does *not* appear to be on the Windows partition.
More verbose:I have an older MacBook Pro (3.1, running Snow Leopard) that I recently refitted with a new 240GB SSD HD. With the extra space (it was previously only 120GB) I decided to add a dual boot with Windows 7 using bootcamp. This all went swimmingly well.Encouraged, I decided to follow this Lifehacker article's suggestion and triple-boot the machine with Ubuntu (I'd never used Linux before):So I now have the nice rEFIt boot partition selection screen, and, indeed, I'm up and running in Ubuntu, and enjoying it.
Only one problem: I can't get into Windows any more. If I try to go in through rEFIt *or* by holding down OPT at startup and selecting the windows partition directly, the result is the same: I get thrown into Grub's selector, and selecting the Windows partition from there leads to an error message and a dead end.Having read through numerous postings, I get the impression that Grub is doing something or living somewhere that it ought not to be, but in most cases I've seen, people had accidentally installed Grub onto the Windows partition (or indeed onto EVERY partition). So far as I can tell, this isn't the case with me. Here's my boot summary:

I am trying to boot a cd on an iMac G3 and I can't get it to boot. (hence the question)
I have tried pressing the 'c' key, the option key, the control key, the apple key, etc, etc, etc.
I have looked around Google and it showed me an old thread on the forums the guy figured it out but he never said what he did.

On a MacPro4,1 with two CPUs and an ATI4870 graphics card, none of the ubuntu cds boots correctly. With the latest 10.04 releases (server and desktop) some boot messages appear on screen, but after some USB initialisations everything halts.
9.04 does not even start loading the kernel. Up to now I tried the 32bit variants.
Has anybody here gotten a similar configuration to work, I am talking about a MacPro not a MacBook Pro.

I have successfully installed ubuntu on a seagate goflex hd and can get it to boot with using a usb cable and refit on my mac. But I cannot get it to boot with a firewire cable and I have not seen any instructions on how to do this with an intel imac, only a ppc.
The mac does recognize the external hard drive when I hold the option key when I turn on the mac, but I get a "no bootable device found" error once I select it...same thing happens with refit and firewire cable. Any ideas on how to get this to work? I am ok with running it via usb cable, but would like the firewire option.

I have ubuntu 10.04 installed on my MacBookPro7,1 (dual boot with reffit). Everything works fine. Today I closed my laptop and open it later again and saw a black screen with a blinking cursor. I was not able to send any keys to it. So I powered down (off button) it.
After Booting It I saw some kernel message, no errors, and then it stops and everything is freezed. Again no keystrokes can be send. The last kernel message is something about scsi. I tried to remove the "recordfail" in the grub2 menu but it doesn't help.

10.04 was working quite well on my Imac G5 with Yaboot for few weeks.
I tried to boot macOSX which failed and returned to Ubuntu which was stioll booting OK as I did not touch the linux part of the yaboot conf.
But Now It won't boot anymore :
- It seems to boot OK till X launching.
- then I get a Black Screen and None of My PC Keyboard shortcuts can get to another tty.
My Next try is to get a PPC LIveCD and try to see if Yaboot.conf is OK.

I installed Lucid Lynx on my Powermac G5 but mistakenly forgot to uncheck the yaboot boot loader. As a result, my LCD's do not received a video signal from the system until after the boot loader had loaded linux.There seems to be no way to boot back into OS X. I would like to replace the Yaboot boot loader with the original Apple boot loader without having to reinstall the system software and just use the <option> key at startup to select Linux when I need it.

I cannot get ubunto 10.04 to boot on my 1.2 ghz 256 mb ram powerpc ibook g4. I downloaded/ burned the live disc and it worked just fine in my powerpc imac g5 (both g4, g5 were supported I believed)It gets to the screen where I select my image to boot, and that works by it says after failing to load for several minutes: "144.9818211 b43-phy0 ERROR: firmware file "b43-openucode.fw" not found you must go to URL... to download to correct firmware for this driver version".I've gone to the website and found a 43 driver and am not sure how to update/ install it...
the hard drive (30 gb) is shot, kaput. currently no os, though I would like to have a firewire drive with tiger or leopard, and potentially a linux partition if even possible. So here are my biggest questions: can any version of ubunto boot on my ibook from a firewire drive? Can i create a dvd that boots in my ibook that not only has the operating system but also some lightweight application on the dvd so that I can run linux just from the dvd as a toy?I'm not replacing the internal hard drive, it's too costly and not worth it when I have several other working macs running snow leopard already.

I tried installing ubunutu on my macbook pro (7,1 I believe, with lion 7.2 installed) today and ended with result of a nonbooting computer, the ubuntu partition won't boot either! I'll try to explain all the steps.
1. I first installed rEFit.
2. Next I booted from a burned copy of the latest release of ubuntu on a dvd.
3. I created a partition of 5120 mb from the freespace on my harddrive, I made sure to leave the mac partition intact.
4. I finished the install, it said to ejct disc and hit enter, I did, the computer froze. I ended up having to hold the power button.
5. The computer just showed a white screen. It wouldn't boot to the rEFit screen or anything. It just resulted in falling back to lions recovery partion. Disc utility couln't verify ubuntu's or lion's partitions.

where I can find details on how to dual booth OSX 10.6.8, and Ubuntu 10.10 on Mac Mini 2010?
I have the partition already setup for Ubuntu - and have already installed refit - but when I try and boot from the Live CD, the screen goes into power save mode and I can't see anything.
