Hardware :: Create Boot CD For Booting External Disks On An Apple IMac?

Apr 2, 2010

Is it possible to create a boot CD to boot external volumes on an Apple iMac 7.1 (which has an older firmware version and cannot boot external disks, unlike the MacBook Pro 5.1 which can do it, at least with grub-legacy which is all I'll ever use until EFI boot becomes available). There is some promising stuff on www.pendrivelinux.com, and I'll try it, but the instructions are for Windows, and I am not sure how to translate the menu.lst entry to linux (I suppose it would have to be entered in the "automagic" section). Of course I don't want to create a bootable flash drive but to use my external volumes that already boot on the MacBook Pro without altering them, except for installing the ATI video driver (but I have no problem booting in low graphics mode).

Until karmic there was a trick to make the iMac mistake the external volume for an internal one (the root partition had to have the same UUID as the internal root partition), but this does not seem to work for lucid. Anyway this UUID trick is dirty and causes problems when you want to edit the internal partition (which is the point of the external boot - you get a customized maintenance environment that boots much faster than the CD).

Ubuntu / Apple :: Booting 10.04 On Imac With Osx 10.6

Aug 20, 2010

I just installed the latest version of Ubuntu on my intel-based iMac with OSX 10.6 (Snow Leopard), but I don't know how to bring it up.

I partinioned my hard drive for it. I inserted the CD and pressed C when restarting my computer for it to come up, then I installed it on the partition. It was done installing and said the computer must restart now, so I pressed OK. I got a black screen with a bunch of white text saying something about an error. It was pretty much "frozen" (I didn't know how to get off the screen), so I turned off the power manually by pressing the power button. I turned the power back on, but I get no option for Linux. I tried putting the CD back in, and it boots from the CD but it's still the non-installed version. So I thought maybe it didn't install, so I pressed install again. It said to choose where to install it, but my partition of free space said Ubuntu was already installed on it.

I'm really confused and don't know how to get it to start up when I turn on my computer.

EDIT: Here's some more info about my mac incase you need it:

OSX 10.6 Snow Leopard
4 Gb of RAM
250 Gb hard drive (29 Gb partitioned for Linux)

Hardware :: Spamming Plenty Of Output About External Disks On Booting

Aug 4, 2009

When my 2 external usb hard drives (just storage based on ext3) are plugged and I'm booting Linux, it starts spamming plenty of output about these devices. I think during loading sensors daemon. At the end hangs. Previously I've noticed that the same happened on terminals. It was annoying, because spam was flooding even vim editor. I see this after major system update or rather new Linux installation. What I supposed to switch off to avoid this unwanted output?

Ubuntu / Apple :: IMac G3 Will Not Boot From Live CD?

Feb 21, 2010

I can't install any flavour of Ubuntu 9.10 onto my new iMac G3. Here are its specs:

iMac G3 New World (Indigo)
350MHz G3 Processor
6GB Hard Drive
Slot Loader (CD only - not DVD)
Mac OS 10.3 Panther

The drive does work - I've played music from CDs on it, and it does allow me to view PDF files stored on data CDs. I can even view the Ubuntu CD through the Finder on the desktop. It just really doesn't want to boot from the CD.

I've tried multiple Linux distributions (all of them PPC compatible).

Ubuntu / Apple :: How To Get IMac To Boot From Disc

Mar 25, 2010

I want to install Ubuntu on a PPC iMac.It is running 10.2.8.I'm looking for a ppc version of Ubuntu that will fit on a CD-R, the iMac has no DVD reader.Where can I find this?Also, I'm not sure how to get the iMac to boot from disc. It doesn't seem to respond to holding 'c'. Also, when I hold 'option' during boot up it shows me a screen with a picture of a lock, it wants me to fill in a password, but my user's password won't work.

Ubuntu / Apple :: IMac G4 Will Not Boot From Live CD?

Aug 15, 2010

I presently have an iMac G4/700Mhz machine I want to try Ubuntu on, but I cannot get it to boot using the 10.04 PPC Live CD. I get to the boot prompt, and no matter what I type, the system halts when the screen clears and comes up, and each time it does so, it comes up different colors (I've seen green, red, yellow, and grey so far). I've tried the special boot arguments that apply to this system when you press the TAB key, and all of them end the same way, so I'm at a wee bit of a loss here.

Ubuntu / Apple :: Boot 10.4 Live CD On New IMac?

Sep 18, 2010

I'm trying to boot ubuntu10.4 live CD on my new iMac (iMac 11,2, core i3). The screen goes black at start of boot and stays black. The CD stops reading after a few minutes and that's that. Just to see what else doesn't work I tried ubuntu10.10 beta live DVD. That boots the splash screen - already better than 10.4 - and gives the language menu and the boot option. The boot starts and some text scrolls up the screen quickly. Then the screen goes black, etc. Tried to set boot option vga=771 - no good. Boot option nomodeset - no good. Booting suse11.3 live CD also gives scrolling text and a black screen. All these discs worked on my old Mac Mini Solo (2006). Looks like something's different about booting a live CD on the new iMacs. Anyone else trying this?

Ubuntu / Apple :: Boot Camp On IMac?

Feb 20, 2011

A while back, I used boot camp to dual boot OSX and Ubuntu on my iMac. It was fine, worked well - but I eventually took the partition off because there was some software corruption in OSX. I reinstalled OS X and now I want to dual boot Ubuntu. I can't! I created the partition - like last time, in Boot Camp, and I installed Ubuntu - I made sure to keep Grub on the Ubuntu partition only. But when I go to reboot (you know, after it finishes installing) I press option/alt and the Ubuntu partition does not show, only the Mac partition. Why is this?

ed: One thing that I remember is that I formatted the Ubuntu partition ext4 - I don't recall whether or not I used ext3 before, and do not know if that makes a difference.

Ubuntu / Apple :: Lucid Will Not Boot After Install (iMac G4)

May 22, 2010

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,

Ubuntu / Apple :: 10.04 Stalls In Mid-boot On 700mHz IMac?

Apr 8, 2011

I'm installing Ubuntu 10.04 on a 700mHz "lamp" iMac for a home school. I managed to install Ubuntu 10.04 via the alternate iso, but when it boots up it only goes as far as a black screen with "Ubuntu" in white lettering above four dots of which only three are colored red before it stalls. I just can't trick 10.04 to booting up past three red dots.

Ubuntu / Apple :: 11.04 And 10.04 On ILamp IMac Freezes On Boot?

Apr 28, 2011

I tried to boot live Ubuntu (using 11.04 daily build) and 10.04 on my G4 iMac (the so-called iLamp) 15" but it freezed on boot. I tried using both the "live" and the "live video=ofony" options with no difference.The result is always a white or blank screen (randomly). With 10.04 I obtained a little bit different result: a yellow screen!These are the main characteristics of my iMac (obtained with the system profiler):

PowerMac 4.2

Ubuntu / Apple :: 20" 2009 Intel IMac Won't Boot LiveCD?

Mar 26, 2010

in an attempt to demonstrate just how compatible our college Macs are (please hold the tomatoes) I'm trying to install Ubuntu Karmic alongside Mac OS X Leopard and Windows XP Pro SP2. The problem is, I hold down 'C' to boot from the CD, and all I get is a black screen with a flashing DOS-style cursor. If I boot it without holding C, it works just fine, booting into either Mac or Windows (whichever I specified).This is understandably irritating, and I'm trying to figure out the source of the problem.

Ubuntu / Apple :: IMac Display - Screen Will Just Go Black When Boot From A Live CD

I've been installing Linux Mint with OSX on a bunch of iMacs, and its been working perfectly excpet for one of the iMacs. The screen will just go black when I boot from a live CD, but I can hear the login sound play. It's strange because all of the other iMac's run the live CD just fine. What could the problem be? I don't know what I can do to troubleshoot this problem.

General :: IMac Boot From Partition On External Drive?

Apr 3, 2011

I have the following "setup:"

iMac (no internal drive/dead) --------- (Firewire) ------- [[MAC OS X]]

I routinely use the firewire drive to boot MAC OS X.However, I would like to boot from the linux partition of the USB drive. This linux partition had linux installed on it from a live cd, and during that process, I told the installer to install GRUB on the usb drive (which happened to be /dev/sdd).My question is, how do I get this disk to show up during the iMac option-boot? Currently, only the firewire MAC OS X option shows up. I have read about rEFIT, but that appears to install it to the Mac OS X disk (would that still work?)...Also mentioned was installing rEFIT to the internal EFI system partition, but I don't know if that is wise.

Ubuntu / Apple :: IMac G4 "iLamp" Locks Up On Boot?

Feb 15, 2011

I've got a friend's iMac G4, 700Mhz i believe, aka iLampI couldn't install using the desktop version b/c of size restraints.So I finally got the alternate version installed.Now, at boot up, I get an option to choose b/w Linux and the CD. If I wait a while, it continues to load from yaboot. It will then continue again. But before anything else happens, it will lock up. All I see is a black screen. Pressing the caps lock key will not toggle the LED light.

Now, when I get to the yaboot prompt, I can interrupt it and try to boot the partition with different parameters. By the advice of other forum posts, I've tried typing "Linux 1", but the same thing happens (i dont get a command prompt, just a black screen). I've also tried to boot from the alternate CD again and do a rescue and a rescue-powerpc. No go.I've also tried booting into a Live CD (i think it was 10.04 desktop version). That booted into a black screen as well. The only thing I can think of is trying previous versions of ubuntu

Ubuntu / Apple :: Manual Installation On Already Created Partition To Create Dual Booting PowerMac?

Jul 15, 2010

I have booted from the .iso cd I made on my Mac last night and was tempted to install it on a 6gb partition that I have on my main HDD but was a bit scared to go past the fourth (or so) step in manual installing where I pick that partition and *do what?* Is it going to install the OS on that partition and leave everything else alone to give me a dual booting PowerMac? It doesn't quite say. I am fearful of screwing up my little ol' machine. Can anyone direct me to something that gives a step by step in manual installation on an already created (HFC+) partition to create a dual booting PowerMac?

Ubuntu / Apple :: IMac G3 - Won't Install

Oct 25, 2010

I remembered about my old iMac G3 and currently had OSX 10.2.8 installed on it but its too old to support flash so no ..... or anything (why I stopped using it) I do remember gnash working on it along time ago when I had Ubuntu 4.10 installed, gnash is just really glitchy but that was quite a long time ago I used it so I'm only assuming they have made some updates as Ubuntu progressed.

I tried have now tried 4.10, 6.04, 6.10, 7.10, 8.04, 8.10, and 10.10 all for ppc using the alternate installer cause the desktop installer just makes the iMac restart when I tried it with 8.04 I think it was so I just stuck with the alternate installer method and EVERY one of those versions of Ubuntu fails to install the base system..

I don't know what it is or why this is happening because that is the same disc I used before with 4.10 and it now cant find a file, I tried re downloading 4.10 and burnt it again on my dads laptop (Toshiba Satellite with Ubuntu 10.10) at 8x on a CD (the iMac has a CD ROM only). I can't figure out what to do, I just downloaded the Desktop installer for 10.04 and the alternate installer for 10.04 as well and I'm going to burn both of those and see what happens.

Every install I tried to do I did a full whip to the hard drive so its a fresh install of ubuntu only. I thought maybe something was wrong with the hard drive now so I tried 10.2.4 again and it installed fine and wanted me to update to 10.2.8 again so I turned it off and tried 10.10 again and nothing is working. It's going on a week soon I've been messing with this old computer trying to get it working and everything is failing on me

Apple :: Can't Get Ubuntu 10.10 On My G4 IMac PPC / Sort It?

Oct 26, 2010

I decided as ubuntu 10.10 was so good on my old laptop i would install it on my old G4 iMac 17" LCD.

However, All I ever get is a black screen.

i tried the alternate install and it all seemed fine until it reboots and.... Black screen!

I burned the ubuntu 10.10 desktop ppc cdrom nice and slow, checked MD5 sums and verified disk etc...

I put it in the cd tray booted up, and let it start the lice cd... For a split second I saw the ubuntu loadscreen before it disappeared in a hiss of static and went to a.... Black screen.

I've tried alt-command F2, but don�t get a console

i am at a loss as to what to do next. I partitioned the whole HDD for ubuntu during the alternate istall. So until i can get Ubuntu up and running, I have a very heavy paperweight.

Ubuntu / Apple :: Installation - 7.04 On IMac G3 (os 9.2.2)?

Mar 22, 2011

my partner and I have been trying to wipe the mac os 9.2.2 (UK version) and replace with ubuntu 7.04 (previous forums have mentioned this is the most stable version of ubuntu for the G3).

We bought this iMac G3 the other day, cheap, for our sons room... homework, research, music etc. He's used to the windows system that the Mac os looks both boring and confusing to him. so we thought we'd go in between and use the ubuntu os.

Any who! downloaded the iso for ubuntu 7.04, burned the iso image, alternate cd install of course. the only problem we are having is getting the disc to boot at start up on the iMac. (cd rom doesn't have a tray, I've seen this question asked before). the cd burned fine, the disc works on other systems. but when it comes to boot up on the iMac, nothing happens. press and hold down c, cd drive turns the discs a few times then carries on with the original mac os 9 start up.

I am finally coming around to selling my iMac G3s and eMac. I will reformat the drives in them and put on Puppy Linux for the iMacs and Xubuntu on the eMac. If I can, I will repair OS X on them all and will dual boot if possible. All of this will be done using the Intel iMac via Firewire. I would like to know if there is a way to make these machines any faster (without money) and "safer" so the next owner feels sure they won't be failing on them soon.
