    One Button Installer, 'OBI'

    One Button Installer, 'OBI'

    The One Button Installer is described at the following wiki page.

    The plans are to develop that page into the main tutorial and to move it to some other location within the Ubuntu wiki. This tutorial thread will stay at its present location. I intend to keep it up to date with references to the wiki page and other links. I also intend to describe new features and systems to install.

    The One Button Installer itself can be installed from a compressed image file with terminal window commands or with the shell-script mkusb, described at the tutorial Howto make USB boot drives.

    A special version for very old computers (without PAE capability or which cannot boot from USB) is shown at this wiki page

    Typical cases for the One Button Installer

    Tool that is easy to use and just works

    The normal linux installers that come with iso files are complicated to use or freeze during the installation process, and you want a tool that is easier to use and just works.

    Replace Windows XP

    Replace Windows XP because you want the computer to work faster or smoother with an Ubuntu based linux operating system, or at the end of life in April 2014, when there will be no more security updates for Windows XP.


    You want a simple method to backup (and restore) your whole installed linux system. The One Button Installer combines installation, backup and restore in one set of tools.

    Your own portable Ubuntu based linux system

    You want to make your own linux system portable and port it to a USB pendrive or to be installed in another computer to be used by yourself, or to be uploaded to the internet for sharing with other people. The One Button Installer can do it in a simpler way than to remaster the code and make an own iso file.

    Download a virtual disk for testing the OBI in Virtual Box

    Virtual Box can connect to peripheral devices and mass storage devices via USB, but not boot. Instead, the OBI can be installed to a [virtual] hard disk drive. The virtual machine will boot from the first virtual disk, so you must put it on top in the 'storage managing window'. Later, when you want to boot from the installed system, you must switch the order of the virtual disks. There are two compressed virtual disks with the OBI in

    Expand the new one (with OBI version 3.3) and connect it to a virtual machine, and you can test the OBI in Virtual Box without the extra problems to get the OBI into the virtual machine and installing it.

    KVM can boot from a USB drive and even an image file

    If a 64-bit host operating system in a machine with hardware virtualization is available, install a KVM virtual machine. Otherwise Virtualbox might be more efficient.

    Install a virtual machine using KVM, qemu, and virt-manager according to this wiki page

    It is fast and very similar to installing and running in a real system.

    You need no special virtual disk file for KVM. You can mount the OBI image file (after expansion from img.gz to img) and it can be used as a virtual SATA disk. If it is the first disk, the virtual machine will boot from it.

    And the standard tarballs can be imported via sftp, wget or lynx to this virtual SATA disk and used in order to install systems to a second virtual disk.

    Follow the instructions in the README file step by step

    Just a reminder of the README file...

    Make you own tarball

    This is a link to a detailed description how to make your own tarball


    OBI versions 0.7, 1.0, ... :


    1. The dialogue has been improved by using screens made with the linux program dialog. It means a menu style similar to that of the alternate installer and the mini.iso. See the attached pictures.

    2. The compression of the dd-image files and the tarballs is improved. The original compression was using gzip. It is still available, but now xz compression is also available, and xz compression is more than 20% more efficient, often 30% (meaning that the size of the compressed file is 20-30% smaller than a gzipped file). xz is slower and needs more memory, but not too much. During a test with low RAM, 128 MB, extracting the tarball with xz used 62 MB while extracting with gzip used 49 GB. Downloading is usually the bottleneck, so small files are preferred.


    1. Own directory for tarballs (plus symlink)

    Put and find the tarballs in

    ~/tarballs -> /tarballs
    2. Download tarball

    There is a new download system with a dialog menu, that you run from the main menu with

    d Download tarball

    3. Make tarball

    From version 1.1 xz is the default compression in mktbl. You can also enter a tarball name as parameter #3 when you run mktbl from the bash shell.


    Basic and advanced OBI level

    Most users are recommended to use the basic OBI level. This means that the OBI will install a system from a tarball into a whole device, typically an internal hard disk drive or a USB 3 pendrive. It is easy and takes only a few minutes to install a system at the basic OBI level.

    The advanced level opens the door to dual boot (mainly for internal disks) and a first FAT32 partition for access from Windows (for USB pendrives). In the advanced level the OBI will let you select the partitions. It means that you can install a system from a tarball into two partitions, one root file system partition and one swap partition. This way it is possible to create a dual boot device with an existing (already installed) operating system. It is also possible to create a separate data partition with an NTFS or FAT32 file system, that can be used by linux as well as Windows.

    The intention with the advanced level is to edit and create partitions with Gparted (booted from a 'regular' boot CD/DVD/USB device). One partition is labelled 'obi-root' and one (smaller) partition is labelled 'obi-swap'. Such partitions can be identified and selected automatically in the advanced level, but manual selection is also possible.

    Editing partitions is risky (so you need a good backup) and it takes long time (hours) to shrink an existing partition with a lot of data (Windows), so that there will be space for new partitions.


    In order to make it more convenient to use the advanced OBI level (introduced in version 1.2), there is now version 2.2.

    The underlying operating system is upgraded to Ubuntu version 13.10 and Lubuntu-desktop is installed and tweaked to create a graphical desktop environment with desktop icons for the main tasks during installation with the One Button Installer.

    A USB 3 pendrive with at least 8 GB is recommended for the graphical desktop environment. But there is also a flavour of version 2.2 with a text desktop environment, which is suitable for very old computers. A 4 GB pendrive is big enough for the text version.

    You can find some USB pendrives that are good booters in this link Howto help USB boot drives


    This version is mainly a bug-fix update from 2.2 including updated pdf documents. The operating system (13.10) is also updated/upgraded.

    New feature: the OBI will share an existing swap partition, when selected at the advanced OBI level.

    There is a new and special version of the 9w installer, the OBI-9w installer

    This version is made for very old computers without PAE capability. The One Button Installer in run from the 9w installer's debian system. Now there is a super light-weight installer, that can

    - install from CD, DVD and USB
    - create not only single boot but also dual boot systems.

    Prepare partitions with Gparted and run the One Button Installer at the advanced level to create dual boot or multi boot system.

    There are special tarballs for the 9w installer, and these tarballs come with the iso file.


    This version is mainly a bug-fix update from 2.3 (and 2.4 OBI-9w) including updated pdf documents. The operating system (14.04 LTS) is also updated/upgraded.

    New feature: the starter menu will set the default item (command line) in a logical way prompting to download and select tarball, select OBI level and then install a system. Two-digit partition numbers (/dev/sda10 ...) are recognized at the advanced OBI level.

    USB 3 pendrives with at least 8 GB are recommended for this version with Lubuntu desktop. 4 GB pendrives are still possible for the text version. See also this link


    This version is a major improvement, implemented for ToriOS but not published here.

    • dynamic focus in the starter menu
    • improved recognition of devices (using the function list_drives)
    • final warning screen with red background
    • improved help function


    This version is a bug-fix and polishing update of the starter script. Current mkusb and mkusb-nox are installed and there are updated pdf documents. The operating system (14.04.1 LTS) is also updated/upgraded to the current date (2014-12-28).

    This version number is reserved for for ToriOS.


    This version selects tarballs depending on the version (12.04 LTS or 14.04 LTS)

    • improved 'dltbl' - to download tarballs
      • selecting repository for tarballs depending on the version of the system underneath the OBI (12.04 LTS or 14.04 LTS)
      • some bug-fixes: modified for-loops and md5check

    • improved 'confirm-partition' - pre-selected root and swap partitions should *not* be mounted
    • a text based One Button Installer based on Ubuntu mini.iso 12.04 LTS is released


    • zmktbl, a graphical tool to make tarballs, is added to the OBI system
    • The host Lubuntu system is updated (2015-07-29)


    This is a bug-fix version:

    zmktbl, select-part2: fix for buggy(?) zenity --list in trusty: ans=${ans%|*} ...


    select-part2: fix to identify partitions to unmount: double-quotes (") removed from target in

    umount ${line:0:10} 2>/dev/null
    df|grep ${line:0:10}>/dev/null

    • more robust syntax in the file '$partitions'
    • in the functions confirm-partition, select-part2, autoselect
