Ubuntu / Apple :: Unable To Boot From LiveCD (MBP)
Sep 21, 2010
I have a MacBook Pro 6,2 that try as I might refuses to boot from live CDs. I have rEFIt installed, and both of the liveCDs I've burnt for 10.10 (32 and 64 bit) do not show up either in rEFIt or when I hold down "option" as my mac boots.
Both CDs will run perfectly as either liveCDs or Installations in Parallels, but I'm looking to (hopefully) someday replace Mac OS entirely with Ubuntu. Being completely unable to see these liveCDs presents a bit of a problem though..

I've got a Macbook Pro with rEFIt and Windows 7 installed (I'm not sure if this is relevant), and I'm running into an issue when I try to boot from the LiveCD or a USB (64 bit, due to 4GB RAM).
If I boot from the CD, the Ubuntu splash shows fine, but I run into the error message:
"(initramfs) Unable to find a medium containing a live file system"
I tried then to boot from the USB using rEFIt, but it just gets stuck at the grey screen with tux. The disk images both are OK.

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.

Basically this morning, I decided to format my Win7 as it was getting really slow and I did so with no problems. I also have a Linux Mint OS on dual boot. Since I was springcleaning my windows partition, I decided it was a good idea to do the same to my linux partition.
I downloaded the latest version of Linux Mint (Julia) and burned the LiveCD. Now here is where the problem lies, when I restarted Windows and chose to boot from the LiveCD, it didn't work. No joke. There was just a little underscore blinking for a long time before it went back to GRUB which prompted me to select an OS to boot.
However, when I went into my old Linux Mint OS and restarted the machine, the LiveCD worked... to a certain extent. It would load and look as though it was ready to install Linux Mint 10 but the moment it got to the option screen, the whole screen turned into a checkered and jumbled mess.
At this point I thought it was the LiveCD or the .iso file. I had an Ubuntu LiveUSB for recovery purposes and I tried that. The exact same thing happened. Can't boot the LiveUSB if I restarted from Windows, but works when I reboot from Linux. BUT still the same checkered screen that doesnt respond.
Did a bit of googling and reckoned it might be something wrong with my GRUB. Did some updating and didnt make a difference.
Then I tried the Super Grub Disk and STUPIDLY uninstalled GRUB. (Note that booting to SGD had the exact same problem - can't be done if I rebooted from Windows). Now I can't access my Linux Mint 9 cos the the bootup screen (mbr) only has Windows 7 as an option.
Remember me mentioning that I can't boot from any CD/USB/recovery CD when I reboot from Windows? And now that I can't access Linux, there's no way for me to do any form of recovery!
I've tried using the command prompt utility at startup recovery but to no avail.

I re-installed my Windows OS today and wanted to install Linux Mint as a dual boot. Before the reinstall, I used the LiveCD Gparted to expand my C: from 25 to 30 GB. All went smoothly.After the fresh Windows install, I went ahead and installed all the hardware drivers and other programs I need. Now I don't seem to be able to boot from LiveCD successfully.On booting from CD Rom, it goes up until the screen with the Linux Mint logo and stays there (I tried giving it time, waited an hour and nothing).Thinking something was wrong with the CD, I tried booting a USB drive. Used Linux Live USB creator to use the same .iso file to boot from. It seems to 'freeze' at the same point.
Formatted the drive, and installed UNetbootin and used the same .iso file. This time, booted it in compatibility mode. A few commands flashed by (links to pictures below), no idea what it means. I've taken a picture, maybe you can tell me what it means? This is the only lead I have to figure out what went wrong (Even if I don't want Linux installed, booting with Live CD to recover data is invaluable)
Pictures I took of the messages in compatibility mode:

P.S: I don't know if this is important but I thought I'd mention it. I was in Gparted (in the LiveCD) when the screen froze. I had to hard boot the laptop again, and I haven't been able to get the LiveCD to work since.

I have an Acer Aspire One Netbook. Everytime I try to "burn" the live 11.2 GNOME CD to an USB drive (1GB) it fails on boot. I've tried unetbootin, the application from pendrivelinux.com as well. When it boots, it usually can't find the image. So I have to type in the name of the image by hand then press enter. I actually type the below in:
boot: openSUSE_Linux_(GNOME)
So it starts loading the image in text mode. I don't mind this, except it stops when it tries probing for the CD/DVD ROM.
rebootException failed to detect CD/DVD or USB drive
It just stops pass there. I've tried to add in the options acpi=off, but do I add it in before or after I enter in the image name? BTW, it doesn't boot in my laptop either.

I have a serious problem! I downloaded and burnt Ubuntu 10.04 and then chose it as start up volume in Snow Leopard's start up disk preference dialogue and although Ubuntu runs successfully from the cd (I'm typing from it now) I can no longer boot into OS X at all.
I have tried all of the different short cuts at boot up to no avail, even trying 2 keyboards. It insists on looking for the Ubuntu disk and if it is not in the drive comes up with an error message stating that a system disk cannot be found.
Is there any kind of tool on Ubuntu that will let me change the start up disc/interact with the Mac's efi settings? I previously had refit installed but this disappeared just before I booted the cd, is it worth using the live cd?
I tried booting from a Tiger dvd but it wouldn't let me do so, it just returned me to the ominous "System disk not found" message.
Does anyone have any kind of idea? Perhaps some kind of shell script that will reinstall refit? I'm guessing that any kind of dvd designed for PC will prob boot, any kind of OS X recovery disk compatible with MBR available?

I have downloaded the 64 bit iso and burned the CD-ROM per the instructions. The CD is verified. When I boot the mac, holding down the C key, I get a menu of options relating to Ubuntu. If I choose the trial run from CD then the CD drive starts up but the screen goes blank and I end up with just a blinking underline cursor in the upper left hand corner of the screen. Does anyone known if one can, and if so how, to boot the live CD on a Macbook Pro 5,2?

I have an old iBook G3 12" Dual USB (M7692LL/A) with 128Mb extra of RAM.
I was trying to boot Ubuntu from an external USB DVD and a FW CD drive, and the same thing happened. When I select the disc from the boot select screen and press enter, the colors get funky and it stays like that for minutes!

I wanted to try to Natty 64 on my wife's Macbook Pro 2.1 (Core 2 Duo + ATI X1600) and I got a FAIL.
Indeed the LiveCD doesn't start at all, I don't even get the Try/Install GUI, just a sort of choice:
Code:
1.
2.
Select CD-ROM Boot Type : And a blicking cursor, I have no keyboard control at all, and I can't get something other than switching off the Mac.

i have downgraded from Ubuntu 10.10 to Ubuntu 10.04. I've had some bumps along the way and finally was able to install 10.04 successfully. Right now, my computer will not boot from the HDD and will only boot from the USB drive that the LiveCD is on. When I reorganize to set HDD as primary boot, i get:id-laptop login:d-laptop password:and I can put that in but then it just gives me a command line that ends with ~$ i believe. How do I get it to boot from the HDD instead of from the USB without running into this problem?
If I resequence the boot to HDD as number two, it will juts go into the LiveCD mode. Am I supposed to reinstall 10.04 again? I know 10.04 was successfully installed because it said it was and it needed to restart so i hit the restart button. It also had my old desktop picture there and all my files AND i checked the system info before restarting (it confirmed that lucid lynx was running).

This might sound like a really daft question but how the hell do I install CentOS 5.5? I cant find any guide how to install the dam thing. I ve downloaded "CentOS-5.5-i386-LiveCD-Release2.iso" & burnt this to a CD. I then booted my server form this CD. I see a very nice colourful screen which says "Automatic Boot in 10 seconds". After 10 seconds nothing happens. I then rebooted the server & this time I hit the enter key, I now see a menu with the following options:
Boot
Boot (text mode)
Network Instillation
Memory Test
Boot form local drive
If I try the "Boot" or "Boot (text mode)" options nothing happens. Selecting the Network Instillation appears to boot the install I then see a blue & red screen asking me to choose a language I picked English hit OK selected UK as the keyboard type hit OK Installation ethod...... Ive chose Local CDROM but the message says: The CentOS cd was not found in any of your CD drives.

I am having problems with an old laptop I have. It had windows xp on it, and after loaning it to a friend it wouldn't boot up. I decided to try linux, but I'm having problems loading it. If I try to run the liveCD it halts because its unable to mount root. If I try to install it just doesnt work well (will stop at different points).
So I figured a mem test would help. I am running the test, currently its on test #6, but it is coming up with a ton of errors. Does this mean I need to replace the RAM?
If so, this is the computer I have. Will this RAM work? I've been out of the tech game for awhile so not really following hardware anymore, and just want to double check.

Recently I got a new computer:
Intel core 2 duo E7500 chipset
Gigabyte s-series GA-G41M-Es2l
Intel G41 express chipset.
I inserted the ubuntu 9.10 disc in and I clicked on livecd option and few seconds latter I got a trace back report. Is it that my motherboard doesn't support ubuntu or what is wrong. Why can't I boot into livecd?

I'm trying to boot off a USB LiveCD of Ubuntu 9.10 in order to save some data off a botched UNR install. However when I try to boot off said USB drive, I get this error:
Code:
process 2425: arguments to dbus_pending_call_set_notify() were incorrect, assertion "pending != NULL" failed in file dbus-pending-call.c line 596 The error repeats constantly until I turn off the netbook (EeePC 1008HA).
I've tested the USB drive using the "Check disk" option in the boot menu, and it comes up clean.

I am currently triple booting between Windows, Mac, and Ubuntu. I was having problems booting earlier and somehow Grub2 got replaced by Grub 1.5 command line. I can't boot into Ubuntu anymore, I can only boot into a LiveCD, but I can't figure out how to re-install Grub2.. I tried using Terminal to install Grub, but it still did 1.5 command line. I did sudo apt-install grub and everything. Nothing worked..

Ubuntu Lucid Lynx 64bit, HP ZV6000
I've boon doing a lot of reading on booting problems in 10.04 and it seems as though there are a lot of booting issues after the upgrade or, in my case, out of the blue. I've only been using Ubuntu for about 6 months now, dual-booting my WinXP box, and for the most part haven't had any issues. I upgraded to 10.04 via the update manager (or whatever it was that said: there's a new version of Ubuntu out there, please update) sometime in May and never had a problem (although I did choose a wrong setting for the dual boot but that just meant I couldn't get into WinXP).
Out of the blue one day, after being on the laptop for a few hours I decided to shut down and go outside. I did the same normal shutdown I always do and shut the computer down. I came back to it a couple of hours later and it wouldn't boot. The HP splash screen pops up (as normal) giving me the opportunity to go into the BIOS if needed and then the GRUB 1.98 loader shows the available versions: Ubuntu kernel, ubuntu kernel and Win partition. If I choose either of the two Ubuntu kernel's my screen goes blank and I get a flashing curser in the top left corner. And that's it. I've let it sit for an hour and nothing.
I tried to boot from my LiveCD (9.10) but the computer will not boot from the LiveCD. I took out the HDD and slid it into a USB connector and plugged it into another computer and only the WinXP partition shows. I can't even look into the non-OS partition I created specifically for circumstances like these. I tried the "GRUB> find /boot/grub/grub.conf" command from the GRUB menu and nothing. It comes back with a "find is not a valid command" notice. I have some music and videos on there I'd really rather not lose. Unfortunately, the laptop is too old to boot from a USB (BIOS isn't being updated anymore) and I can't think of any other options. As far as I know, my only other option is to format the drive and start over.

for the past couple of weeks, I have been booting from an Ubuntu LiveCD. Here's why: When I boot my computer (emachines E528 laptop), it gets to the BIOS loading screen (the one where you have the option to press a function key to get to the BIOS settings), then it goes to a black screen and looks like it is going to load GRUB, but instead of loading GRUB, the computer reboots. It does this endlessly, unless I insert a LiveCD. So, it's not the BIOS. That's good. When the Mint GUI (Linux Mint was the LiveCD I was originally using as I just happened to have it on hand) loaded for the first time, I checked all of the hard drive partitions and they all seemed to load fine. So, it's not a mechanical problem with the HDD. That's good.
At this point, I figured the MBR had become corrupted somehow. Now I wasn't really sure exactly where the MBR was, or how it all worked, but I was pretty sure that if I just reinstalled GRUB, everything would be hunky dorey. Unfortunately, I hit a road block when trying to install GRUB. That's not good. I am trying to follow the instructions in this thread, but I get the following error:
Code: grub> find /boot/grub/stage1
Error 15: File not found So then I tried following the instructions here, but I don't know how to tell which drive is sda1, sda2, etc. I'm guessing there's some terminal command to figure it out, but I don't know it and Google was less than helpful. I feel like something that basic should be easy to find, but I digress.
At this point, I am getting very close to backing up everything and reinstalling everything. Only problem with that is that I am not sure how to access the files on my Ubuntu partition as they are encrypted (I wrote down the key when I started it up, I just don't know how to bring up a prompt that will let me enter the key). I really don't want to reinstall and set everything back up, but if I have to I will.
So, I guess I just need to know how to tell which partition is associated with which sda#, or how to access the files in my encrypted Ubuntu home folder, or (hopefully) someone who can tell exactly what's going on from why I have posted and can give me instructions for fixing my problem. Also, here's a breakdown of how my hard drive is partitioned. Not sure why, but I thought this might be helpful: linky.
TLDR: How do I tell which partition is associated to which sda#? How do I open my encrypted home folder from my Ubuntu partition? After reading my whole post, is there any further insight you could offer that I may have overlooked?

Ubuntu 10.10 doesn't boot at all. The liveCD only boots once every like 30 attempts, installing from liveCD froze, but the Alternate CD worked and installed ubuntu. Now when I try to boot into it using GRUB, it freezes at the beginning of the boot process.With normal boot it freezes at line: Starting AppArmor profiles Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox.With recovery mode it freezes even before showing me anything
A little kinda like the liveCD, if I try like 30 times, it might manage to boot once in normal mode.That line keeps on repeating, the the xxx.xxx integer changes each time, and this goes on forever.I tried removing my floppy drive, but it didn't help.I tried to boot with fd0=noprobeThe one time it booted, when I restarted, it froze while trying to restart.

I've been trying to get my LiveCD (9.10) to boot but I can't get it to work. I get it to the main screen then I select "Try Ubuntu without making changes to my system" and I get a whole bunch of information to pop up... looks like techno giberish to me. Then I get what essentially looks like a prompt, except no matter what I type I get nothing out of it. I just want to be able to use my liveCD without issue.
P.S. I'm using a Toshiba Satellite Laptop that has windows 7 installed.

I'm having a lot of trouble with a PC that has been running Ubuntu for ages, since about 8.04 I think. I've run the distro upgrade a few times and it was running 10.04, but for some reason won't boot anymore. So I'm trying to do a fresh reinstall but I can't get the LiveCD to boot. I'm trying to install 10.04 AMD64 desktop.If I leave the CD to boot, I get to a Busybox screen showing the error "No init found. Try passing init= bootarg." and an (initramfs) prompt. This is all displayed at 1280x1024 res - the native image of the screen I'm using.It's an NVidia chipset - an older one. So I tried hitting a key during boot and putting the nomodeset option on. I get the same error, but at a lower resolution

I upgraded from 9.10 to 10.04 this past week. Foolishly, I tried to finish it quickly, and let grub fiddle with my Vista volume, sdb1. I realized it after I agreed. Shucks! Now, my computer won't boot unless I go to the ROM. A bit of history, my original 9.10 install was on a formerly dual boot 160 Gig IDE drive. This one was really just my main Ubuntu drive (sba1). I would have gladly gotten rid of the useless NTFS side of it, but never wanted to bother. The terabyte SATA drive is my Vista volume (and general data drive). It has no Ubuntu nothing on it. When I wanted to boot to Vista, I would boot to sda1 via GRUB2 and then select Vista. It would then come up to the Vista Bootloader, and I'd select Vista and boom, things worked fine.Then I did my ugrade. Somehow, the original grub on sda1 got messed up. I have no idea how. I get the somewhat familiar error: the symbol 'grub_puts_' not found and unceremoniously dumped to a grub rescue>_ prompt. Great! I can enter the ROM and tell it to boot from sdb1, then grub comes up exactly like before and I can select Ubuntu and 10.04 comes up!
So my MBR on sdb1 has now been ruined by GRUB2. Now I know I should never have allowed GRUB to write to sdb1, but why did it also mess up sda1?To make matters worse, I can't use the various boot-to-LiveCD solutions rather common out there. I downloaded the ubuntu-10.04.1-desktop-amd64.iso and burned it. But since I got my new 25" monitor for Christmas, I guess it's too much for the poor old LiveCD disk. I upgraded via the Update Manager, so the video wasn't an issue. Now, when I boot from the LiveCD, the screen turns black and that's it. Take the disk out, reboot, and you're back to the ROM or that beautiful grub rescue>

A 10.10 LiveCD (burned from the ISO image) won't boot my system using my LG GSA-4167B DVD drive which has been working fine for several years.Upon boot, Ubuntu starts to boot up. The splash screen appears. The drive activity light flashes for a while and it sounds as if things are progressing. Then the drive gets into a funky pattern: click-click-spin fast. click-click-spin fast...
The purple splash screen is still present, with 5 red dots (not flashing) The LG drive happily boots up a Windows CD, BartPE CD, Ultimate Win CD, Macrium recovery CD, Gentoo distro CD, etc etc. Only the Ubuntu 10.10 LiveCD is problematic.Oddly, a 10.04 LTS LiveCD obtained with the book "Ubuntu for Non-Geeks" boots OK. (that CD is not burned at home). The LG GSA-4167B is 2005 vintage, with IDE interface. I swapped it for an even older (2004) LG DW1610 DVD drive. That drive boots the 10.10 LiveCD just fine.
I downloaded the 10.10 ISO image a second time and burned a second copy. Same results. The LG website had new firmware available for the GSA-4167B drive, so I downloaded that and flashed the drive. No change - it still won't boot the 10.10 CD. Are LG drives known to be problematic with Ubuntu? Are the CD-DVD drivers on the LiveCD limited in their functionality? If I go out and buy a new drive, should I avoid LG products? Perhaps I'l try burning the 10.10 ISO on to a DVD and see if that makes any difference.

I have Fedora 14 installed on my laptop (Installed with few issues) and I'm trying to install ubuntu on my desktop. I had ubuntu 10.04 installed before on a second (250gb) hard drive (Windows 7 on the other 1TB drive) with a few issues and kinda screwed a few things up trying to upgrade to 10.10. So, I said screw it, and downloaded the live .iso for 10.10 (x64) and burned it to disk. I boot from the live CD and choose the install option to use entire 250Gb disk. I choose my options, including to download updates and install 3rd party software and let the install run its course. Everything seems to be going fine and it asks me to restart. So I say yes, the disk pops out and the screen goes dark... and then nothing happens. The computer's still on but hasn't restarted yet. I hit the del key (Which I use to enter BIOS) and the computer finally restarts. I enter BIOS and tell it to boot from the 250Gb HDD, save and exit. However, it gets stuck at the point where it (It, I assume to be the motherboard) says "Loading Operations System ..." and with a blinking cursor on the line underneath. Nothing happeneds.
I tried again just this morning using the same procedure. I'm once again stuck at the "Loading Operating System .." screen.
EDIT: After poking around a bit more, I remembered I was confronted by a GRUB menu when I booted into Windows 7 HDD. So, I selected Linux from the menu and all seems good. Does anyone know why this is? It's very odd, well at least to me. Why would GRUB be on the windows hard drive? Is this something I should be concerned about?

The computer I'm using is a Dell Vostro 1000. If you need any specific stats, let me know and I'll post them, but I don't have access to anything that will list them.
As of this afternoon, Grub will not longer boot. I don't know what prompted it; the only change I made was to the power management settings and installing IcedTea. It brings me to "BusyBox" after saying "No init found. Try passing init= bootarg." Then it brings me to some command prompt that doesn't respond to most bash commands I know, and it says "(initramfs)."
I had that problem two or three weeks ago after Fedora broke Grub, but I fixed it by using "grub-install" in an Ubuntu LiveCD. (No easy task to find what command I needed to use, though.)
But, now the LiveCD won't load. It hangs on the splash screen that just says "Ubuntu" with the dots underneath that indicate it's loading. This exact same disk (and I've reburned it, of course) worked fine when I had to clean up the mess that Fedora made. I tried switching to a terminal at the point where it hangs and there are no messages at all.
I already tried using acpi = off and burning the disk at the slowest speed (from two different computers).
I tried with the Mepis LiveCD, but the GUI just shows a blank screen. I can run commands using Alt+F2, and the cursor is visible, but that's it. I can switch to a terminal, but I can barely use grub-install at all as it is, and I can't figure out how to mount a drive through the command line.
An older version of a Sabayon Linux LiveCD works fine, but, unfortunately, doesn't do anything useful. I haven't tried Knoppix because it never worked on this computer.
If there are any other distros that I can use to run grub-install (preferably lightweight; I'm getting impatient downloading so many 700 mb iso files), I'm open to suggestion. Those are just the ones that I'm familiar with already.
