Really Weird One: Install Ubuntu on Partition, Bluetooth Hardware Disappear

So ... I cloned my Mac OS X install onto an external drive, repartitioned my hard drive, cloned my install back onto my hard drive, and installed Ubuntu on the new, smaller partition.
But now, on the Mac OS X install side, as far as Mac OS X is concerned, Bluetooth doesn't exist -- it's as if this system doesn't have Bluetooth hardware.
I haven't even the faintest idea where to start. Any ideas?

I have the same problem (I have an nforce3 board) where sometimes both eth0 and eth1 won't work, and the only way to fix it is to shutdown and start over (oh, and I don't think it's an Arch64 problem, since it happened to me in Arch32 as well).  It doesn't happen often enough to bother me though, so I haven't really looked into it.  As for problem where eth0 and eth1 switch, maybe this will help (so far it is working for me).
From  /etc/udev/readme-udev-arch.txt:
- The "proper" way to configure net interfaces to hold static names within udev rules.  Add lines like these to a custom rules file such as
  /etc/udev/rules.d/01-network.rules:
    SUBSYSTEM=="net", SYSFS{address}=="aa:bb:cc:dd:ee:ff", NAME="lan0"
    SUBSYSTEM=="net", SYSFS{address}=="ff:ee:dd:cc:bb:aa", NAME="wlan0"
- To get the right mac address use this command:
    udevinfo -a -p /sys/class/net/<yourdevice>
- Make sure you use lower-case hex values in your udev rules.
- NAME= determines the name of your network card.  Use these names in your
  network configuration in rc.conf as well.

  • Really weird one- KT3 Ultra 2

    I have had this board for awhile.  Never a problem.  I decided to boost the ram from 512mb to 1gb.  I put in a stick of 2700 512ddr.  It worked and past all sandra soft burn tests.  When the system restarted I got errors. I removed the memory, and reset the cmos.  What it boils down to is that if I change the date/time to the current date/time, the computer starts to boot into windows then restarts.  If I leave the date time as default (which rite now is 11:42 am febuary 24th 2003) the system boots into windows and works perfectly.  
    I have replaced the battery, I have flashed the cmos again, I have reset it 20+ times.  And it works fine as long as I dont touch the time/date.  This reset happens if I set the time/date either in the cmos or on the windows time screen.
    Anyone have any ideas??

    VIRUS ALERT!   You may have a trial program installed that runs on startup and that it doesn't let you to change the date. But I cannot explain how it can get control of your XP so bad  X( .   Check your startup programs using msconfig, use sysedit to check also on those .ini . Maybe  you can PM me with your findings because I found this very cool so I would like to have it also to play tricks on friends  :D
        Windows XP has an integrated module that checks the time - so if you have an invalide date will prompt you on startup (valid are only since XP's release) but will not restart your system.
         What the hell is on febuary 24th ?  Is it a virus with this name?

  • Installing Ubuntu 12.04.1 on a partition MacBook Pro?

    Hi,
    I am attempting to install Ubuntu 12.04.1 on my internal hard-drive on a brand new MacBook Pro. I have managed to partition the hard drive ok. But when it cam to attempting to install the alternative operating software on it. I arrived at a purple screen of death.
    I am using an installation disk that I burnt myself from my previous Mac. After I partitioned the Hard Drive using the disk utility I input the disk into the computer and then restarted the computer holding down the alt button to boot into the other partition. I reached the slection stage and there were four options. The Macintosh HD, the new partition on the hard drive, and two disk icons, one labelled Windows and the other labelled something else (I can't quite remember). I clicked on the fourth option and was guided to a purple screen that said.
    Try ubuntu without installing
    Install Ubuntu
    and one other option which again I cant remember.
    I clicked on install Ubuntu and my computer screen went blank and everything has now stopped reponding to anything I try and do. I have tried the normal escape routines but nothing happens. What is happeneing and how can I get control of the computer back, and finally what is the correct way of installing Ubuntu on the section of the hard drive. HELP!
    Thank You.

    Sorry for your troubles but what is wrong with OS X? The only other OS that Apple supports being installed on a Mac computer is Windows and for the newest versions of OS X only Windows 7.
    You could install all different types of OSs into a virtual machine program like VMware Fusion, Parallels or Virtualbox.
    Or maybe you should of bought a Windows PC Notebook as with them you aren't restricted in what OS can be installed natively.

  • Making new partitions after installing Ubuntu 11.1

    Hi everyone
    First of all, sorry for my bad english, i'll do my best to explain my problem.
    I have a 2010 13" Macbook Pro (7,1), with OsX Snow Leopard running on it.
    Recently, I decided to install Ubuntu (11.1 version), by partitioning the main Macintosh HD using Disk Utility as usual, with 3 new partitions: a swap partition, a "storage" partition ad a partition dedicated to the OS.
    After the installation, everything was going well: with refit at the start i can choose if booting with OS-X or Ubuntu and it works with no problems.
    Yesterday I saw a tutorial on youtube where I saw a Macbook user explaining how to install three operative systems, using ReFit at the start like me.
    So, today I decided to give it a try, but Disk Utility doesn't allow me to modify the macintosh HD partition again. I can set a new partition, deciding the dimension and the file system format, but clicking on "apply" to make the changes I get this error:
    "Mediakit mediakit reports no such partition".
    Does anyone knows a fix for this one?
    Sorry if there was already a topic about a similar problem, I didn't noticed it.

    Try Andrei Cerbu's post here or see TS1538: iOS: Device not recognized in iTunes for Windows, in particular section 5, forcing a driver update.

  • Getting Partitions Ready to Install Ubuntu on ideapad Z570

    Hi,
    I've been doing some research around partitioning and installing Ubuntu on my Lenovo ideapad Z570 as part of a dual-boot set-up with Windows.  I've pretty much read all of these forums and webpages which pertain to partitioning, etc.
    http://forums.lenovo.com/t5/IdeaPad-Y-U-B-V-and-Z-series/new-disk-partioning-and-one-key-recover-fea...
    http://forums.lenovo.com/t5/Linux-Discussion/Factory-Windows-7-partitions/td-p/535363
    https://help.ubuntu.com/community/forum/installation/Partitioning 
    http://en.wikipedia.org/wiki/Disk_partitioning 
    Ideally, what I would like is to have a partition of 80Gb for Windows, a partition of 80Gb for Ubuntu, a large partition for data that Ubuntu and Windows can share, plus whatever other partitions Lenovo and OKR need.
    Having read through the above forums plus other information regarding partitions, I've come to understand the following things:
    That OKR will not work if I make any changes to any of the partitions.
    That a hard-disk drive can only have maximum 4 primary partitions or 3 primary partitions and an extended partition.
    That the extended partition may in turn be subdivided into several logical partitions.
    That Windows must be installed on a primary partition with the boot files.
    That Ubuntu can be installed on a primary or a logical partition.
    Are all of the above correct?   
    If so, my questions are:
    If I resize and create new partitions, is there no way that I can re-run OKR and create new back-ups?  I'm guessing OKR will not work if I resize now but then run into problems during Ubuntu installation.  But assuming I resize and install Ubuntu successfully, can I then get OKR to work, recognising the new partitions, and create new back-ups?
    I currently have three primary partitions (a hidden tiny hidden system one, I assume for recovery, the large C: with Windows, the logical partition, D: Lenovo with Lenovo progam files and drivers, and a hidden "LENOVO_PART" partition which I assume is where OKR creates some sort of system image...)  Does that mean that I already have 3 primary partitions and one extended partition, which is also one logical partition, or is the second partition an extended partition subdivided into the primary C: and the logical D:?
    I can live without OKR as I can use alternative programs to make back-ups.  But it would be nice to have it.
    My main concern is how I can safely resize to accommodate a drive for Ubuntu and a large data drive.  
    I'm thinking of two paths:
    First is to downsize the C: drive to 80Gb, then create an extended partition with the space and divide that into two logical partitions, one for ubuntu and one for data.  But the fact that the D: Lenovo partition is already logical confuses me...
    The other is to merge the C: drive with the D: drive, then create an extended partition with the two logical partitions (ubuntu and data).  I'm afraid this way I might ruin the Lenovo programs and drivers...
     Sorry for this lengthy post but I want to show that I've tried researching it but I'm stuck....  Any advice at all?  Any advice would be very much appreciated.  Thanks

    I just installed Linux mint, which is based on ubuntu, on my Z560 here.  You can keep One Key Recovery functional if you want to, but there is a bit of work to do and you need several items to accomplish it.  In my case I am working to setup a triple-boot system of w7, mint and eCS 21 (OS/2) here, so my requirements are stricter than any as eCS isn't happy with the way w7 created the partitions on my 500G drive and I had to rework that first.
    I first booted w7 and did the initial setup followed by creating the Factory Default Recovery DVDs for the system.  I then booted my DFSee CD and used it to change the type of the recovery partition from 12 to 07 to permit w7 to access it.  I rebooted w7 and used the disk management feature to shrink all four of the factory partitions to suit my needs.  I then booted DFSee again to change the type of the recovery partition back and confirmed OKR function with resized partitions.  I then created the current system recovery DVDs for the system.
    At this point I needed to deal with the partitioning issues.  So I booted DFSee again, changed the recovery partition back to 07 again and made images of that partition and the D: partition on external storage, as I had found out earlier that the current system recovery DVD appears to only address the C: drive.  I then deleted all the existing partitions and recreated them in a form acceptable to eCS, being sure to keep them in the same order in the partition tables and on the drive as w7 had them but consolidating them to place all of the free space in the logical partition after the D: drive and before the recovery partition.  I then used the current system recovery DVD to reload the now acceptable C: drive and then restored the D: and recovery partitions from their images.
    I then created the logical partitions I needed to install eCS and mint on the drive.
    In your case I believe you could simply use w7 to resize things, create the current system recovery DVDs to deal with any failures, and then use DFSee or other tool to move the existing partitions where you want them.  Once this is done confirm w7 and the OKR system still works and then go ahead and install ubuntu in the free space you created.
    Dave
    PS: the small initial primary partition is the w7 boot manager and appears to be handled with the C: drive.  The OKR makes use of the larger primary at the end of the drive marked as type 12 as opposed to 07 in the partition table.  All partitions are formatted NTFS.

  • Really weird problem -- won't download mail from one sender

    I'm having a really weird problem. Apple Mail won't retrieve mail from my Gmail account via POP3 from one sender only. All other mail is downloaded normally, except from a particular sender. What could be causing this? Thanks.

    I am trying to remember and research something about the Junk filter and Gmail accounts. Have you checked in your Junk mailbox, if Junk in enabled and there is a separate Junk mailbox?
    If you click on my name to the left, and look in the bio line of the resulting Profile, you will find an email address you can reach me with. If you email me at that address, I will send you a Gmail address that your sender can test sending a message to me at my Gmail account.

  • Can't install ubuntu with wubi on Bootcamp partition

    Hi,
    with Wubi you can install ubuntu linux inside a Windows partition without any kind of disk partitioning.
    Here https://discussions.apple.com/message/15115515#15115515 you can see that someone installed successfully ubuntu through wubi on bootcamp partition. I tried too but when I choose in what partition want to install ubuntu, have only the D: drive (Macintosh HD) option. Wubi can only be installed in C: (bootcamp), in fact when I tried to install on D: I got obiviously some error.
    Windows version is 7 Professional 64 bit, bootcamp version 3.3
    Thank you in advance!

    The Ubuntu community https://help.ubuntu.com/community/Intel_iMac is very good/informative on this.

  • Is My Iphone 3gs the only one that does this really weird glitch

    ok i have a issue i looked everywhere and i did not see anything in the forums about this
    when i am replying to a text message and auto-spell types something so i hit the back button/delete key to rewrite what i want to type and it does not delete the text it just goes over the letters and doesn't delete it and sometimes the cursor will just get stuck and sometimes the cursor when i am deleting text will keep going over the letters i am typing and doesn't do anything , so as i hit back/delete button on keyboard it just keeps going over the letters and does not delete its really weird, and this is my 2nd new iphone 3gs for a different issue, and they both did that.
    what i want to know is if this is a hardware problem and should i take it in to get it replaced again which i hate doing,since i got a good iphone 3gs this time...has this happened to anyone else,or does this happen to anyone else
    any help would great thank you

    Well if it happened to 2 different iphones perhaps something is corrupted in your backup restore file. By restoring your new phone with this old backup restore file u may be copying over the problem.
    Solution: Restore and setup your iphone as a 'New' phone instead of restoring from a previous backup. This should solve your problem.

  • How to install Ubuntu alongside Arch Linux?

    I already have Arch installed and I have downloaded the Ubuntu 13.04 ISO. My grub file is auto generated following the beginners installation guide since I don't have much knowledge about GRUB2 commands or configuration. I looked up https://wiki.archlinux.org/index.php/GR … _arguments - The Ubuntu ISO section, but didn't understand it. It instructs to to create a /archives but I don't know whether I have to create a new partition or do it in the one where Arch is. Also do I have to install Ubuntu before doing this. But wouldn't that overwrite my existing "grub.cfg"?
    Can I do something like deleting the existing grub.cfg, installing Ubuntu on a separate partition and then add Arch to the Ubuntu grub menu. If this can be done, please tell me exactly what to delete in "/boot". I'm thinking the wiki's method is much more difficult and would prefer to add menu entries to Ubuntu's grub rather than the existing one. I have seen many people doing this on Google, but they all install Arch after Ubuntu rather than the other way round.

Doesn't it have to be boot since it is the only one left?
    Please help with detailed instructions since I am a complete novice at these sort of things (boot and all). Contrary to the norm, I installed Arch first, and am curious about Ubuntu so I want to try it out. Post any other information you'd like to have, and maybe I'll post a gparted screenshot if needed.
    P.S- Not sure whether I'm allowed to post about installing some other distro, so I posted in this section. Please notify me via email if I'll have to remove it, and I'll do so.

    I am not sure to what senjin refers, as I have never had a problem with ubuntu controlling grub, with one exception:
    Sometimes ubuntu's OS-prober can't find Arch (so it disappears from the automatically created menu).  Maybe this is the problem senjin found.
    One way around this is to have a file in your Arch /etc that OS-prober looks for when it searches for other operating systems.  Look for a file in your ubuntu called /etc/lsb-release.  Make an appropriate copy in your Arch install, and OS-prober will always find it.
    Another way to ensure OS-prober always finds Arch is to mount the Arch / partition before [re]running update-grub.
    Finally, since you don't really need to ever generate a new menu entry for Arch - since it will always be the same - you can simply run update-grub once, copy the menu entries generated into /etc/grub.d/40-custom, and then disable the OS-prober (so it will only ever update the ubuntu entries (what I do these days).
    grub, run from other distros, losing "Arch" seems to be a fairly common problem that is easily solved by any of the above.

  • My iMac is acting really weird lately....

    So I got my iMac in 2008 I think. Around that time. So sometimes it's slow but it still works fine... Initially I had 1 GB of RAM and last year I got 3 more so now I have 4GB of RAM. (I don't know whether this may be related to my problem but I thought I'd mention it) My iMac has been acting unusually weird for a week or so. It starts up soo slow, it takes about 7 minutes. Yesterday it started up just fine though.... Today I wanted to start it up and I got to the desktop screen but the little applications on the top bar (the wifi, volume, language preference, caffeine etc) wouldn't all load (just a few of them were there)... and then I got the spinning wheel.... which wouldn't stop spinning... so I shut it down because nothing would work and I started it up again. No luck. I tried again and this time I was stuck for 15 minutes at the grey apple logo thing before I got to the desktop screen... Also, I have an app called Caffeine. A few days ago it disappeared from my top bar without having done anything... I use it so that the desktop doesn't go into sleep mode/screensaver mode... so I noticed the screen saver and I thought it was weird because I haven't had screen savers for years. The first time it started to act strange was a week ago, when I started the iMac and it told me to enter my apple ID and password - but I never logged out of it! This happened multiple times. Once, I entered everything correctly and it told me that it was incorrect. When I restarted, it got me right into my apple ID.. Also Chrome was asking me for a password for 'local items' - which is really weird because I never had something like that. Or at least never seen that before..... I also searched for viruses and repaired some permissions but it didn't change much... now it doesn't ask me to log into my apple ID anymore but it takes so long to start up... But once it's finished starting up it works flawlessly. I'm really worried. What's happening to my iMac?

    Do the following:
    Repair the hard drive and permissions using Disk Utility.
    Backup your files to an external drive.
    Boot from your installer DVD.
    Erase the hard drive.
    Reinstall Snow Leopard.
    Upgrade Snow Leopard to 10.6.8.
    Reinstall any third-party software from original media.
    Restore your data files.
    Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Drive Partition and Format
    1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
    4. After formatting is finished quit Disk Utility and return to the installer. Complete Snow Leopard installation.
    5. Download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8
    The easiest way to do the backup step is to connect a formatted, empty hard drive of the same capacity or greater than your internal drive. Clone the internal drive to it.
    Clone using Restore Option of Disk Utility
      1. Open Disk Utility in the Utilities folder.
      2. Select the destination volume from the left side list.
      3. Click on the Restore tab in the DU main window.
      4. Select the destination volume from the left side list and drag
           it to the Destination entry field.
      5. Select the source volume from the left side list and drag it to
          the Source entry field.
      6. Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.

  • How do I install LION and partition SL 10.6.8 run on same imac?

    Hello If one could tell me step by step instructions:
    I would like to install LION ( because icloud), but can I install LION and partition the OS so that my imac can run both SL 10.6.8 and LION?
    SL 10.6.8 still runs some applications that LION will never be able to run.
    So I really need LION installed,but also have SL 10.6.8 partitioned so I can run imovie HD6 with plug ins with SL 10.6.8.
    Please if this can be done so I can run Lion and SL 10.6.8 on same computer
    thank you so much in advance
    please advise
    scott

    Wow, thank you Niel.  I have looked on this site and have found many different ways listed on partitioning and using 2 OS on a computer.  But there steps seemed very long and tedious- but of  course if that is what is needed then i would do it that way. Again i was seeing a lot of different ways. But yours seemed direct.
    I went thru the steps up until using the thumb drive for LION to install. I went in to  disk utilities, i selected mydrive, clicked on the partition tab, and then i saw i had 96.7 GB available--without changing SL10.6.8 HD size.
    it looks like you can drag and increase/decrease the partitions with the mouse control.
    I really need LION for icloud, and if so all other applications EXCEPT imovieHD6
    So i need to run SL for imovieHD6 the other applications like word, adobe creative suite, excel, etc ican use LION.
    do you recommend having the partitions equal in GB?
    I have a 250gb hard drive
    should I split the partitions evenly between the two OS?
    or should one OS get more GB than another?

  • Using iWeb to publish my mobileme photo gallery -really weird bugs help plz

    I have a really weird problem and have tried searching the forums already with no luck.
    I'm using iWeb09 to put mobileme photo album on my website. When I initially add the widget onto my page, the widgets will show a "preview" of what pictures are in the gallery if you hover your mouse over it. Later during the day, I'm not sure if I did anything to mess it up but that "preview" is no longer there. It's just a black box. It still works however if you click on it because it takes you to the mobile gallery.
    The only way for me to fix it was to delete the mobile me album and create a new one. Then re-add the widget onto my iWeb.
    This has happened twice to me already and I cannot figure out why it happens. I'm sorry if my description is vague. Please help.

    There is no point in re-installing iWeb, because after you have published it really is not an iWeb problem - if there is something not working on uploading the files, then it is really nothing to do with iWeb after html pages have been created.
    If you are using Fetch to upload, then you have obviously published your site to a local folder? If so, are the photos there when you look at your local site? If they are there when you publish to a local site, then it is an error in uploading and if photos do not show, it means that some things are not being uploaded to your server correctly.
    Have you tried using Cyberduck instead of Fetch? Cyberduck or Transmit are two of the better ftp programmes to try.

  • Need help with installing Ubuntu on Lenovo Ideapad Z500.

    I just bought a new Lenovo Ideapad Z500 yesterday. It came with Windows 8 pre-installed. Now, I also want to install Ubuntu over it. The disk is partitioned as follows:
    Disk C: - 880 GB (approx)
    Disk D: - 30 GB (approx) (I don't remember exact partition, as my laptop is currently at my home).
    Then I thought, I would better re-partition the C drive into 1 or 2 small drives. So, I shrinked the C drive by going into "Disk Management", and then created 3 more partitions - 240 GB * 2, 300 GB * 1, and left the C drive with 100 GB space. I didn't modified the D drive.
    Till then I didn't went through any infomation over internet. But, now when I went through this forum, I found out that my OKR won't work now, that I still have to confirm when I go home. So, now I'm worried. I scanned through so many post here, and no where found a way to install Ubuntu on Ideapad Z500.
    I also read that it will be possible to run OKR, if I can re-store the partition to it's original. I think this can be done, since I just have to remove the volume I created, and allocate the memory back to C drive. And it will be back to original state, as I didn't modify D drive (correct me if am wrong, or if it can't happen).
    So, the major question that I want to ask is, is there no way to partition my disk, and install Ubuntu in one of them. 

    hi rohitjain-rj,
    Welcome to the Lenovo Forums.
    On a Z400 Touch running on Windows 8 preload, shrinking the the C-Drive under Disk Management and creating multiple partitions on the unallocated space and then reverting the partition back to original made the One Key Recovery work as normal - haven't tested this yet on the Z500 as there's no available unit but chances are, it may also work.
    In installing Ubuntu, have you tried to install Ubuntu via Wubi ?
    If Ubuntu doesn't start, boot into the BIOS (press the OKR button > select BIOS Setup Utility) and set the following:
    Boot Tab
    Boot Mode - Legacy Support
    Boot Priority - Legacy First
    Exit Tab
    OS Optimized Defaults - Other OS

  • Installing Ubuntu 10.4.1 alongside Mac OS X 10.6.4 Problem

    I'm not sure where a posting like SHOULD have gone but this seemed
    the place it might get the most attention, and that's why I posted it
    here. I hope it doesn't offend anybody.
    This is my first attempt at installing Ubuntu 10.4.1 Desktop LTS on my
    Intel mac. I followed the guidelines described in:
    https://help.ubuntu.com/community/MactelSupportTeam/AppleIntelInstallation
    for a Dual-Boot: Mac OSX and Ubuntu. I did the following:
    1. Installed rEFIt (and made sure it works)
    2. Used Disk Utility to shrink my MacHD partition to 200G and created
    a second 119G partition for Ubuntu.
    3. Booted a Ubuntu LiveCD and started the partition editor (gparted).
    I used it to delete the Ubuntu partition created in #2 above. I
    applied the changes and exited.
    4. Started the Ubuntu Installer. Chose to install to the "largest
    continuous free space". NOW IS WHERE THE PROBLEM COMES IN! On
    the last dialog of the installer, it says to click the "Advanced"
    button and choose to install the boot loader (grub) to /dev/sda3.
    THERE IS NO /dev/sda3 LISTED! This is the list presented to me:
    /dev/sda ATA ST3320820AS_P (320.1 GB)
    /dev/sda-1
    /dev/sda1
    /dev/sda2 Mac OS X
    /dev/sda-1
    So, not wanting to screw things up (since I don't know what I'm doing -
    just following instructions) I decided to quit and abort the installation.
    Does anybody have any suggestion as to why there is no /dev/sda3?
    How about what I should do now?
    Thanks
    Ron

    Sorry this isn't an answer to your question, but installing Ubuntu within VMware Fusion is a lot safer and easier... If you don't need Ubuntu for uncompromised audio/video input or output, there really isn't a disadvantage, and being able to run both OS X and Ubuntu side-by-side has its advantages.

    You'll break your Mac direct installing Linux, it's not for the computer newbie, but very well seasoned geeks as Mac's are very different in hardware than Generic PC's and require special skills drivers and software to work with your hardware and control the fans etc. It's hard even on a 10.6. Mac, almost impossible now on a 10.7 Mac.
    Like Joey said, use a virtual machine software, VMFusion and Parallels Desktop are commercial and Oracle's VirtualBox is free.
    I recommend for you to buy the commercial versions as your not too well seasoned yet and you need support which costs money.
    This way you can dump the whole mess and still have control with OS X.
    If you want to direct install Linux, use a generic PC, that's what the boot disks/USB of Linux are made for, not for a Mac.
