    Fix Windows with Linux 

    If your Windows partition will not boot, but you can still boot into Ubuntu using your dual boot option, then there is away to repair your Windows partition from within Ubuntu.

    Check with Synaptic Package Manager to see if you have “ntfs-3g” installed. If you have not, install with Synaptic or type the following lines in the terminal:

     sudo apt-get install ntfsprogs
     sudo apt-get install ntfs-3g

    After that, right click on your Windows partition on your Ubuntu desktop and unmount it.

    Then type:

    sudo fdisk -l

    This will tell you what volumes exist on your system.

    You will see an entry such as:

    /dev/sda1 * 638 12312 93773824 7 HPFS/NTFS

    Next, type: sudo ntfsfix /dev/sda1

    This command will repair and re-mount your NTFS at sda1. If your windows volume is at “sda2”, then put “sda2” instead. It does not matter if you make a mistake here, use of this command on a volume which does not need repair does no harm.


    Ubuntu can also be used to repair the Master Boot Record, but I would advise against the use of this method.

    Install Linux on an old iMac 

    Got an old iMac with Mac OS 9 sitting in the bottom of the wardrobe? Here’s how to update it so you can browse the Internet.

    What do I need to do this project?

    A computer with internet connection and a CD burner.
    An iMac with Mac OS 8 or 9.

    Your computer must have an HFS or HFS+ formatted hard drive. If Mac OS X has been installed, the original configuration of the machine needs to be restored using either the “Restore” or the “Install” disk.

    Your iMac must be fitted with the hard disk originally supplied with the machine. If a larger, third party drive has been fitted, then this has to be removed.

    If you try to install Linux on an iMac with a third party hard drive, you will get an error.

    Once you have got Linux up and running you can then work out how to install it on a third party drive.

    Have you got an iMac with Mac OS 8 or 9 on the original hard disk supplied with the machine?

    Then you can proceed with the installation.

    Okay I have got an original iMac with Mac OS, what do I have to do now?

    Download an “iso” of a disk image and make it into a real CD.

    When you have made your Linux install CD, you can put it into the iMac, and boot it in the normal way by holding the “C” key down before the “blong”.

    What Linux distro should I get?

    If you are familiar with Linux, you can download the PPC version of the Linux distro that you normally use.

    What if I have never used Linux before?

    Then you can download the PPC version of Ubuntu, which is aimed at beginners.

    What if I can’t get PPC Ubuntu to work on my machine? You can try Gentoo linux, which involves a step-by-step procedure.

    I tried to install Ubuntu using the CD image I downloaded, but all I got was a black screen. What can I do?

    Try a different distro.

    What Ubuntu distro should I try?

    Always try the latest version first, if you cannot get that to work, go back to an earlier version and so on. It is likely that a very old distro will be worse, so try the new ones first!


    I tried to install Ubuntu, but I get a purple screen.

    This is normal. You just have to wait a while!

    I have tried to install Linux, but now my iMac won’t boot. Why is this?

    Your iMac has been fitted with a larger third-party drive which Linux cannot recognize.

    What can I do?

    Boot the machine from Mac OS install CD, and re-format and re-install Mac OS 9.

    Hot tip: Holding down the “opt” or “alt” key before the startup “blong” gives you the option of booting from a specific partition or an external drive. The original Bondi iMac does not have this facility.

    If you have a slot-loading iMac, you can boot the machine from a USB flash drive or an external USB hard drive by using this method.

    Connect to Macintosh from Ubuntu 

    Did you know that if you have Ubuntu on your Windows computer that you can enable file sharing to your Macintosh?

    The procedure is:

    On the Mac:

    Go to System Preferences > Network.

    In the Network pane, under “Network Status” make a note of the IP address which consists of four numbers separated by dots  e.g. “”

    On the Linux machine:

    From the file manager choose “Go” from the menu bar and select “Open Location” (at the bottom) enter the IP address of your macintosh computer above. If the IP address is, and your user account on the Mac is “wilkiecat” then it would be:



    If this does not work via a router, or by wireless, connect the two machines directly with an RJ45 Ethernet lead, and see if that works.  If your Linux installation does not have Samba file sharing installed by default, you need to use the Synaptic Package Manager to install it. Type “samba” in the Synaptic search box. Once file sharing has been set up correctly, it will then work via the router or by wireless.

    How to install Open Shot video editor with Blender 


    Open Shot does not work with blender  when creating animated titles. You get the following error:
    No frame was found in the output from blender

    Why would anybody care?

    “OpenShot” is a marvelous FREE video Editor for Linux which is similar in function to “Windows Movie Maker”. It allows you to create 3-dimensional animated titles when used in conjunction with blender.

    What is “blender”?

    Blender is a marvelous FREE 3-dimensional modelling an animation program.  There is a steep learning curve, but it’s FREE.

    Well, to cut a long story short, you want to get OpenShot and Blender working to make all those fancy 3D animated titles on your YouTube submissions. Right? Here’s how:


    Got to the terminal and copy and paste the following from here:

    sudo add-apt-repository ppa:jonoomph/openshot-edge
    sudo apt-get update
    sudo apt-get install openshot openshot-doc
    sudo add-apt-repository ppa:cheleb/blender-svn
    sudo apt-get update
     sudo apt-get install blender

    Installing by this method will put the latest version of blender on your pull down menu under graphics.

    You now need to change instances of “CENTRAL” to “CENTER” in an XML set-up file.
    for 32 bit Ubuntu type the following on the command line:
    sudo gedit /usr/lib/pymodules/python2.6/openshot/blender/*.xml
    For 64 bit Ubuntu:

    sudo gedit /usr/lib64/pymodules/python2.6/openshot/blender/*.xml

    Now in gedit hit “Control-H”, this will pop up a replace dialog.

    Search for “CENTRAL”
    Replace with “CENTER”

    There are three instances to be replaced. Save the file and close.

    Now, open up the Synaptic package manager and install:


    If your current version of blender still does not work with your current version of OpenShot, install version 2.59, which is here.


    Install the version for your operating system. For 32-bit Ubuntu, this is:

    When you download this, choose “open with archive manager”, and extract the archive to your  Home folder (or any other folder you find convenient)

    Fire up Open Shot:

    In the OpenShot preferences, enter the path to the blender execuable:

    e.g. /home/yourname/blender-2.59-linux-glibc27-i686/blender

    If your name is “Fred” then it would be

    You can have two versions of blender on the machine at the same time. If your latest version of  blender is in your “applications” folder, the path is “/usr/bin/blender “.  If version of blender you have got in your applications “usr/bin” folder is the version which works with blender, then you can use that.

    Currently, Openshot  1.4.0 works with blender 2.59, and Ubuntu 10.10. I know, because I just got it to work!

    These instructions will also work for Linux Mint 10. I am now using this Distro.
