Apple :: Unable To Boot Mac After Trying Out Ubuntu Live Cd / Sort It?
Jun 12, 2010
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?

So I repartitioned my mac hard drive using the disk utility in my mac os. Shrink the mac HD and created a new partition for ubuntu. I installed Ubuntu and everything works fine and it was be able to boot back into mac yesterday. However, this morning, when I was holding down the ALT key at startup trying to go into my mac, no boot options come up, it automatically goes into the ubuntu boot option (grub 2) and i tried to go into the mac osx on sda2 from grub2 but it'll take a very long time and nothing boots up. It just says 'waiting for root devices'. Do I need to insert the mac cd and try to repair the system? All my files and partition are still there so I think its not completely gone.
ps. I have the newest macbook version (6.1?)

Fed up with Windows and ready to become a Linux convert. Here's the only problem:
I've created no less than four separate Live USB distros - all using different USB sticks -
yet my HP Pavilion dv7 refuses to recognize any of them as "bootable devices."
1) Have formatted USB sticks in FAT16 & FAT32 - neither made a difference.
2) Have created bootable USB sticks using Ubuntu Minimal Live install; Ubuntu full Live install; PuppyLinux Live install; even a simple gparted live install - none will boot.
3) Have checked & re-checked that BIOS is set to boot first from USB drive device.
4) 2 of the 4 USB sticks are new, fresh out of the packaging; and 3 of the 4 USB sticks are each from different manufacturers - so I'm fairly certain it's not a issue of a particular brand being incompatible, nor is it due to the sticks being corrupted somehow.
5) Each of the 4 live distros appears to have downloaded just fine - all necessary files appear to be in order.
6) Have tried using Unetbootin, Ubuntu's own live usb tool, and 1 or 2 others - all have failed to boot my HP laptop.
7) Have even tried removing all non-essential hardware before booting - even booting with no hard drives installed - system still returns the error "no bootable device detected."
This laptop is only 2 years old; I know it should be able to boot from USB. I can boot from a (rather old) SliTaz distro on CD just fine - but I need a persistent USB stick so I can easily add packages as needed, etc...s.

I am very much new to Debian. To have a feel and check if my laptop (HP Elitebook 6930p) is supported I decided to use a live USB option. I know how to create a live USB disk using Ubuntu and using the same knowledge I created the USB disk and tried to boot using it. The system starts to boots off the USB drive and then is stuck at a point where it fails to identify my HDD. Here is what I did
a) downloaded the debian-live-508-i386-gnome-desktop.iso/debian-live-508-i386-gnome-desktop.img/debian-live-507-i386.iso (I tried with all 3)
b) created a live USB using unetbootin
c) tried to boot from live environment
My laptop's hard drive is encrypted using SafeBoot.
After all the 3 debian images failed to boot I tried with other Linux flavors such as Mint and Ubuntu. Interestingly Mint and Ubuntu boot. Is there some thing I need to take care of?

I keep running into things that say "Boot from the live CD" and I'm trying to expand one of my hard drive partitions right now using gparted, and I need to boot from the live cd.... but I can't seem to figure out how to do that.
Is this an easy thing?

I am as much of a noob as you could be. I have trying to install ubuntu for 2 days now, I have tryed several versions and several of mint, but I always get this message ending with 'Unable to find a medium containing a live file system' when I start the installation process from the disk.

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
192MB RAM
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).

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.

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?

I have a 8.2 MBP with a 1680x1050 screen and a 6490M graphics card. I'm trying to boot from a usb stick ubuntu live. I'm able to get to the ubuntu menu, asking to install or start live boot, but when I select live boot I get a black screen( backlight is still on but entire screen is black). I've waited at that screen for quite some time with no luck.

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.

First, I know there are numerous threads on grub errors but I have tried all possible solutions and that's why I'm here. My issue is that I'm not able to boot from the grub prompt as described for installing grub from a LiveCD https://help.ubuntu.com/community/Gr...0from%20LiveCD. I can see grub is installed but is missing the kernal and other files. code...
I ran the boot_info script and the output is attached. From what I can tell it cannot even detect an OS being installed, but I've kept everything up to date and never had any issues. Everything was fine yesterday and now this. Also, I tried the Boot Repair CD and that did not work.

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 just reinstalled ubuntu to the new version in my macbook pro, I have rEFIt which properly boots mac osx but for some reason it is not able to boot the new installation of ubuntu.
I made the common installation (ext4 partition mounting / and one for the swap), then I restart I sync the partitions with rEFIt and mac osx boots well but the ubuntu gets stuck and I never get to see the grub.

I download and burnt Ubuntu 10.04 and trying to run the Live CD. It shows up black screen after displaying the red progress dots and nothing happens after that. No CD drive activity is noticed. How can I resolve this problem? I have been troubleshooting it for days!

Im having a serious issue with booting ubuntu 10.04, the issue being it wont boot up at all, after working so well for so long (i suspect some recent dodgy system updates are responsible) so I decided to just reinstall ubuntu from scratch again but wanted to retrieve some important files from my root device. So I am running the live desktop and I can see my previous filesystems under places but cannot mount or open my original root device where the files I want to recover are located, I receive this error msg:"Unable to mount 77 GB Filesystem.

I have installed Ubuntu 9.04 fom a Live CD. My system is a Dell Optiplex 745 that originally had Windows XP installed. Ubuntu is the only OS. Windows XP was removed.
The sytem appears to be running normaly.
When I shutdown (not restart) and then power cycle the computer, I see the Dell splash screen then I get the message: "Errorauto-sensing secondary master hard disk drive. Strike F! key to continue, F2 to run the setup." F1 repeats the message. F2 enters the BIOS setup but does not lead to a fix.
If I place the Live CD in the tray and boot from that, I get to the Ubunt install directory.
If I click "Check disc for defects", then run the check. (I can even interupt the check without completing by hitting ESC), then the system reboots.
I see the Dell Splashscreen.
I see the Ubuntu Live CD menu
I choose "Boot from first hard disk"
Then Ubuntu loads perfectly. I enter my username's passord.
The system runs fine until the next time I shutdown.
How do I get the system to boot directly without needing the LiveCD?

I am unable to boot 9.10 or 10.04 Live CDs.9.04 can boot.When attempting to boot the LiveCD/USB (I have tried both), if I attempt the basic install/start/check CD, I get a blank screen.If I use the option selection to set nomode(something) command (I will verify later, posting from work) with verbose and quiet disabled, I can get further, but can still not boot.Any ideas as to how to get a boot of of the LiveCD?

I've been dual booting 10.10(with Windows7) for about a month. Today is the first time I've encountered a serious problem.
This morning, nothing functioned properly after trying to open up several programs. The computer seemed to be "frozen", although the mouse was working fine.
I decided to reboot, but then encountered an even bigger problem. It failed to boot and got this message code...

On a Lenovo thinkpad S12 2959 and a kingston DataTraveler 101 OK I have been having a lot of strange issues while trying to install the current 10.10 netbook version of Ubuntu.I followed the instructions right below the download for the iso.Basically download the usb live creator and use it.So I did (with no persistence set) and it seemed to work.I tried booting from it and it worked, except that I have to keep pressing keys, I used the enter key and it worked.If I stop pressing enter no progress is made.Then at the end their is some error about no persistent space being available.
and now it is booted, so I try to install a driver and it hangs.so I try to install the OS, and it hangs.So I try to exit and it finally gets to the next screen in the installation after I tell it to exit, but then hangs when trying to get the the next one and it will not continue.

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.

Now that I can successfully load the media, I would like to figure out how to get a DVD or CD to automount in Lucid on my Dual-G4 PowerPC Mac. Right now I have to use the "mount" command in terminal to successfully mount the media. lshw identifies the drive as a Pioneer DVD-RW DVR-105. My other, less unusual (i.e. Cannonical supported) Lucid installs just pop an icon onto the desktop and within nautilus and for video-DVDs they even open up VLC for me and bring up the DVD menu.

A few weeks ago I installed Fedora Linux 64-bit on my HP dv4-1428ca laptop which was running Windows 7. At that time I created a Live USB using the fedora-live usb tool and it booted fine. A couple days ago I decided to try out openSUSE, so I downloaded the 64-bit live-cd image and tried to create a live usb using the SUSEStudio ImageWrite provided in the documentation. The tool kept giving me an error message, so I decided to try unetbootin instead. However, when I tried to boot the live usb on my HP laptop, it presented me with the message.
"SYSLINUX 4.04 EDD 2011-04-18 COPYRIGHT (C) 1994-2011 H. PETER ANVIN ET AL" with a blinking cursor and nothing else. I've tried a variety of alternative programs for creating live USB's (pendrivelinux, linux live usb creator, unebootin), and verified the checksum of the iso file for openSUSE 11.4 64-bit, and still was not able to get past the "SYSLINUX..." message on my HP laptop. However, the live USB does boot on the other computers in my house. Interestingly, if I create a live USB using the tool provided by Fedora, it will boot fine. However the Fedora Live USB tool cannot be used for other distros.
Specs:
AMD Turion X2 Dual Core
4GB Ram
ATI Radeon 3200 Graphics
320 GB Hard Drive
