Ubuntu / Apple :: Drive Will Not Read On TMac After Booting
Mar 21, 2010
Drive will not read on the Mac after booting in Ubuntu!I haven't booted Ubuntu in months (October?), but no hardware changes except for the expresscard. Ubuntu runs nicely in a virtual machine from the Mac side, so I made a fresh VM with Karmic. Couldn't remember the cool apps I had running before (it's been a while), so I booted into Ubuntu to check it out. The HDD was connected and on. (Oops.)It was fine last night on the Mac. I did not notice if it mounted this morning (still in OSX, 10.6.2, Mac sleeping overnight and HDDs on for an unrelated backup). So there is a very slim possibility this has nothing to do with Ubuntu.
Back to Ubuntu, the other external (Firewire 800, HFS+) mounted as usual. Again, I cannot recall if the Fantom mounted. I have not installed drivers for the expresscard/eSATA in Ubuntu (separate driver install is required on the Mac a rarity). I scribbled down the names of the apps I was looking for, and rebooted the Mac to OSX. Where's my HD? Disk Utility sees it as unformatted, and oddly enough, SCSI. If I plug it in via USB, it simply sees an unformatted disk. eSATA is OK with another drive on the Mac.DiskWarrior failed to see the disk entirely with either connection, same in Leopard and even Tiger.Could Ubuntu have confused the partition maps or something? Any thoughts on how I might get it running before I give up and restore the backup?

Doing some experimentation with the XP Home BootCamp on my MacBook, I installed Wubi. (Yes, installed Wubi, on a BootCamp partition, on a Mac). Amazingly, it works flawlessly! But I thought up something while considering the issues with booting from USB on a Mac. My theory is this: Its the EFI and the Firmware which has compatibility issues with booting from USB. But when running BootCamp to use a Windows Partition, it emulates BIOS, which nowadays is good with booting from USB..
So, If I select to boot from Windows, which then leads to another selection asking for Ubuntu (GRUB) or Windows, you could select Ubuntu, which chucks you up at the standard version of GRUB, which to my understanding does support from USB booting? Select your stick and your off. If somebody would be willing to try this theory or correct me, maybe you could think up some easier way in which to boot from a USB with a Mac.

I've tried Ubuntu awhile ago. I popped the CD then restarted my Mac. Upon restarting I usually pressed the C key. The system boots to the Ubuntu CD but when I get to the language selection thing, I cannot use my keyboard. I had to snag my PC's keyboard from the other room to make it pass through the said window.
Is it normal? I selected the "Try Ubuntu" first to get my feet wet.

after loading kernel we get /pci@f0000000/mac-io@17/ata-4@1f000/disk@0:3,/boot/vmlinux : input/output
Every install does this.
What is it with PPC ubuntu lately? Starting with 9.04 it has been nothing but snake bit. And is there any other mirrors beside britain for PPC it seem frequently unavailble or slow.

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

I'm stuck with a problem trying to boot an Ubuntu Desktop 10.10 x64 CD into a white Macbook (2.1 gen, Core2Duo ) I've installed rEFIt, and synchronized GPT with MBR - all ok.
But when I insert the cd (works ok, the same CD on a DELL laptop ) and boot it via rEFIt, the computer hangs with this console message
Code:
1.
2.
Boot from Ubuntu CD-ROM:_
And I can't go further... anyone knows ?

I have an Intel iMac that has about 500 GB of unused space and I was wanting to install Ubuntu or Ubuntu studio or any Linux distro on about an extra 50 - 100 GB of space. I currently have the iMac with a windows bootcamp partition on it as well. Is it too late to partition the main partition and install Ubuntu on it without having to erase it and reinstall the Mac OS and Windows on it? Also, I wanted to try Ubuntu studio on a live CD, but when I hold C and bring up the preboot environment then I don't see an option to "try Ubuntu without changing anything".

I can get ubuntu to work fine on its own (except for sound, a problem for another day), but I can't get dual booting to work.I'm using this page as a guide:URl...I started out with a clean OSX snow leopard install. I ran bootcamp and shrank my 320G hfs+ file system to 160G. I installed rEFIt, and rebooted twice (you don't see the menu after rebooting once). Then I booted from my 10.04 CD, and deleted the partition created by bootcamp using gparted.When I run the installer and tell it to use the largest continuous space, it makes the / file system in partition #5, and the swap partition in partition #5.
I figured that might cause problems with a MBR partition table, so I partitioned manually, and set up / in sda3 and swap in sda4.When I tried to configure the installation of the bootloader, I had a menu of possible places to install it. I picked /dev/sda3, but then the OK button was grayed out.

I would like to triple boot my Macbook Pro. I don't want to use rEFIt. Although it worked on my iMac, it would randomly not load the OS's sometimes.
1. Is there a way to use Boot Camp?
2. I know how to use Mac with the windows xp bootloader. How can i put Ubuntu in too? I got this thing about taking 512 megabytes of the bootloader grub or something like that but I don't get it.

I'm a new Ubuntu user, I just installed Ubuntu today and I'm loving it. But this issue has been driving me nuts all day, I've searched for hours for something like this and all posts were about external hard drives. I installed Ubuntu 10.04 on my MBP 13" then dual booted into Ubuntu. I can mount and access my MBP hard drive, but when it comes to the Mac home user files, I don't have permission to even READ.
How can I change that? I tried doing so by dual booting into Mac and changing the folder permissions and also making them shared folders but nothing worked.

I have a set of Mac software RAID 0 drives that my friend gave me for spring break. I need to access a file on the drive in the Extra folder on one of the drives. It contains some startup settings that need to be changed before I can boot it properly. I loaded up ubuntu and tried to access the drive but only the top level files are readable and when I try to access the Extra folder it says "permission denied." The info on the folder permissions tab is User ID: 501 and Group ID: dialout. Owner permissions = r/w, all other groups/users = none. How can I make Ubuntu read/write to this Extra folder?

After four attempts and diverse partition map problems, I finally managed to install successfully clean versions of both Mac OS X Snow Leopard and Ubuntu Lucid Lynx on my old MacBook Pro C2D (2,1) and a new 320 GB HDD, by following these instructions:[URL]
Now, I've got a big partition for Mac OS X (286 GB) and a small partition for Ubuntu (30 GB, as well as two smaller partitions for grub and swap). However, I'd like to shrink the Mac OS X partition to, say, 35 GB, and use the freed up 251 GB as a shared partition to keep files for access from both OSs. But Mac OS X Disk Utility won't let me resize the Mac OS X partition (and warns that it might not be a smart thing to do, as the disk has been partitioned for Boot Camp, etc).
Is there some way I can resize the partition, or do I have to start all over again?

when booting I can only acces a broken GRUB and this is how I might have done it wrong. I installed Ubuntu the first time using dual-booting which I think is the worst way since it could be done better by using a Virtual Machine such as Parralels or VMware. Well later I noticed that after removing Ubuntu there was still 2 problems 1.when selecting a OS during startup When I select "Windows" it goes to a broken GRUB which displays something like this " Use tab to complete the first commands" GRUB><where you're suppose to type> and I can't type so I hard reboot it. 2. I could not get rid of LinuxSwap. Much later I removed LinuxSwap by booting in a Ubuntu live disk and then removing the partition as well as the Linux "/" and after booting to Mac OS X leopard disk0s1 the Mac OS X system partition was mounted which was bad since it was suppose to be invisible to even the root user unless viewed by terminal on any user.
Now later I reformatted it as "Mac OS X something extended" and at first it was unjointed and impossible to mount and after I reformatted it it appeared as disk0s3. Now the problem appeared.This is the stuff I can do1. I can type some commands in the GRUB but when I typed find / the output is something like can't find /2. I might be able to boot up a live disk however my Linux Ubuntu live disk is broken.3. this is my dad's second hand Mac G5 iSight, not mine and it was a bargain, it was cheaper than my iPad with Mac OS X Leopard 10.5#

I've just tried installing Ubuntu 10.04 on my powerpc. It installed fine, and booted first time ok, but since restarting it just seems to boot into a black screen. My monitor says 'going to sleep mode'
I don't think it's hanging on anything, as I can hear sounds if I play around with the keyboard. Could this be something to do with the resolution being too high? If so, can anyone tell me how I go about changing this?

Few days back i was searching for triple booting my mac through this ubuntu forum.and i ran into command name bless
it was like : bless /dev/disk0s3 --setboot -- device --verbose
i ran it on the terminal after booting it from a Leopard installation DVD in a hope to run linux on my macbook(macbook white..intel m/c 160gb HD..2 GB RAM) after trying all the stuff and eventually everything has stopped booting neither leopard nor windows. i can see the grub for ubuntu loading up but after selecting the option for ubuntu, ubuntu is also not working.
i was using refit as well.i cannot even boot from my leopard installation dvd..windows that was priorly installed using bootcamp is corrupted too.

I downloaded Ubuntu Lucid...something onto a cd and I booted into it on my iMac G4. It brought me to a screen saying things like live is default press tab for more options etc and when I just press enter, the screen turns white, loads a few things, then it turns blank and after awhile, I hear the Ubuntu startup sound but my screen remains blank.

I bought an 8GB flash drive because my D drive doesn't read DVDs. Anyway, my goal is to install Linux ubuntu and have it be my OS (replacing Windows XP). Last night I went to the Ubuntu homepage and downloaded the Ubuntu desktop edition 32-bit and put it on my flash drive. I followed the instructions on how to open and run it, but I was never asked about whether I want Linux to run side by side with Windows or if I want it to replace Windows. It downloaded the whole program, my computer restarted and then (on a black screen) it asked if I wanted to use Windows XP Home Edition or Linux Ubuntu. It's really frustrating because it took a while to download and install it in the first place AND to top that off, when I tried to use Ubuntu it went to a black screen and at the top said that there was an error. So I uninstalled all the ubuntu program and software and now I have a clean slate and want to try this again. I am a complete n00b. Could someone please walk me through how I can go about downloading (w/ links plz), installing and making ubuntu my ONLY OS on my computer via a flash drive? I'm desperate and I don't want to go through all of that and make the same mistake again!

I am running a hp dv701175nr laptop and am booting ubuntu 11.04 from a usb flash drive. I can not seem to find my internal drive that has windows 7 stored on it. I tried to mount it but it give me this error:
Error mounting: mount exited with exit code 1: helper failed with:
mount: according to mtab, /dev/sdb1 is already mounted on /
mount failed
I can't use this operating system if I can't access my windows 7 drive and I really want to use this OS .
EDIT: Okay, so I think I have found my problem, but I don't know how to fix it, there are differences in my mtab and fstab commands, I will post what they say in a second, but I do not know how or what I need to do to change and make the settings right

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?

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).

I'm running Fedora x86_64. I need to setup a virtual machine to do some work on ARM platform. Thus, I've installed QEMU.
Code:
qemu --version
QEMU emulator version 0.13.0 (qemu-kvm-0.13.0), Copyright (c) 2003-2008 Fabrice Bellard
Then, I have dowloaded an ISO image of Debian 6.0 armel.Following instructions on official wiki, I have first created an empty disk image,
Code:
qemu-img create -f qcow debian-armel.img 650M
then I have attempted to boot from ISO image;
Code:
qemu -m 512 -hda debian-armel.img -cdrom debian-6.0.1a-armel-CD-1.iso -boot d
Boot process hangs with the message:
Code:
Booting from cdrom...
639 medium detected
Boot failed: Could not read from CDROM (code 0004)
No bootable device
link refers to Fedora 12, but it seems still unresolved...

I have a Macbook Pro with a b0rked DVD drive, and want to install Ubuntu on it.
I have followed the instructions here: [URL]
But when rebooting and holding ALT, I don't get the option of booting from USB.
Possibly related, when I view the USB drive in Disk Utility it's marked as "Bootable: no" :
I've tried this with two different USB sticks.
I've also burned a Ubuntu install disk from the original ISO, loaded it into another mac and started that mac in Target Disk Mode. Then I connected them with Firewire, rebooted the mac *without* the disc drive, held ALT and chose the shared disc as the boot device. Though weirdly it was named "Windows". Sadly, I then got a message on a black background saying it was not a bootable device.

I have a Ubuntu box with two drives, one of them is where Ubuntu is installed and the other one is where I store all my music, photos and other documents. I recently bought a Mac and I want to be able to access the drive where I have all my documents from my Mac. Is there a way to accomplish this? I've been looking all day for an answer to this but all I can find is how to share a folder instead of a whole drive.
