If you already have a bootable CD or USB Stick with our Labtix installation environment and Laboo Images for cloning, you can skip this chapter.
Thanks to the Labtix tool (LiveCD), all pre-installed learning content in labdoo systems can be "cloned" quickly and easily to new computers using the so-called images.
These images are available in 4 languages (English, Spanish, German, French). So you can select the language in the target country of the IT donation depending on the language and manually upload further learning contents in further languages.
You need two things for that:
Labtix bootable media: this can be a CD or USB stick, that you use to boot the Laptop you want to have restored, into the Labtix einvironment.
External USB hard drive: to store the cloning images and other learning content from our FTP server (Labdoo also provides an already prepared USB Drive to the volunteers, please contact your local Hub).
Labtix: The Labdoo installation environment
To be able to install older and newer computers with a license-free tool, Labdoo.org has a small solution (live-image) based on the Linux-Version Antix which we have called Labtix (a combination of Labdoo and Antix).
In Labtix you will find everything you need to delete old data on a donated computer or laptop, for fast and automated installation proceses in order to obtain a ready-to-ship computer. Additionally, Labtix provides many tools to diagnose hardware, to analyze and solve problems (CPU/processor, temprerature problems, damaged hard drives, etc.)
Once you have downloaded the file, you can create a boot media (CD or USB) from the iso file, which you will use to start and prepare (Sanitation process) donated computers
Creating a bootable USB or CD/DVD from the Labtix ISO
The next thing to do is to convert the ISO file into a bootable CD or USB bootstick (simple copying is not enough!). This often works with file managers of your favorite operating system or with additional tools. For further questions consult the web (search for "cd / USB stick create ISO" and your operating system).
A blank 750 MB CD is sufficient for one CD (DVD is not necessary), USB sticks go from 1 GB (but usually 4 GB is the smallest size you can get). Note for technicians: Labtix has a persistence mode, with which you can save your desired configuration. However, this takes up more space, therefore 4 GB or more is better.
- Download and run a program for creating bootable media. For example, Rufus: https://github.com/pbatard/rufus/releases/download/v3.4/rufus-3.4p.exe (link is external) or another alternative https://alternativeto.net/software/rufus/
(link is external)
- Run Rufus, select the USB device, click on the "Select" button and select the labtix.iso file, then click on ''Start''.
you will find many useful tools for Linux in the following link: https://wiki.ubuntuusers.de/Brennprogramme/
(link is external)
But the easiest and fastest way is using dd. Once you know the device path to your USB key (in the example /dev/sdb) run:
dd if=Labtix.iso of=/dev/sdb bs=1M; sync
(see details explained under: https://antixlinux.com/forum-archive/writing-antix-iso-image-on-usb-flas...)
You can use the following procedure: [http://osxdaily.com/2015/06/05/copy-iso-to-usb-drive-mac-os-x-command ]
(Here we refer to Internet and search engines).
Labdoo-Cloning images method and additional content
For the Fast Restoration method, you need to clone the Labdoo Images. For cloning, you have to download the images first. Images are copies of a complete, pre-installed system (of already sanitized laptops). Linux has a great feature that other operating systems don't have. You can transfer a system from computer A to computer B - and it runs!
You will find these images online in our Labdoo FTP server http://ftp.labdoo.org/download/install-disk/.
You can also download these images from the web browser by selecting the image you want to download, right-click on it, and then select "save link as".
This does not work for folders or for many files! These have to be downloaded individually and of course, this is a lot of work.
Simple methods for downloading multiple files for all common operating systems can be found at https://www.labdoo.org/de/content/zugang-zum-ftp-server
Images are large and the download takes a long time, so If you are familiar with FTP clients, we recommend downloading them directly via FTP (sftp, userlabdoo and password labdoo).
Labdoo Images for Cloning
When deciding what image is best for you, you should consider the following aspects:
- The CPU/processor architecture of the computer you are currently working on (32 bit or 64 bit). You can easily figure this out with the Labtix environment. It will be displayed in the upper right corner of your desktop (see also the video above).
- The target language you want to install.
- The size of the hard disk in the computer to be refurbished. This size is displayed e.g. in the BIOS or after booting Labtix.
The name of an image on the FTP server shows:
There are 4 directories for the 4 available languages:
- English (EN): http://ftp.labdoo.org/download/install-disk/EN_English_images/ : includes versions for 80, 160 and 250 GB Hard drives.
- German (DE): http://ftp.labdoo.org/download/install-disk/DE_German_images/ : requires a minimum of 80 GB HardDrive.
- Spanish (ES): http://ftp.labdoo.org/download/install-disk/ES_Spanish_images/ : requires a minimum of 80 GB HardDrive.
- French (FR): http://ftp.labdoo.org/download/install-disk/FR_French_images/ :(requires a minimum of 80 GB HardDrive)
- PAE32 = for 32 Bit-CPUs ; PAE64 = for 64 Bit-CPUs
- Other 18.04 images Different sizes for 32 BIT-CUPs and 64 Bit-CPUs: http://ftp.labdoo.org/download/archive/18_04_archive/
- xx_04_LTS = version of Lubuntu it is based on, either 16.04 LTS (kept for legacy), or 18.04 LTS (to be used from 2018 on).
imagesThe French and Spanish images occupy 80 GB because they already have the learning content in these languages (Wikis, OER Open Educational ressources,...). The German image is additionally played with German courses, dictionaries in many refugee languages etc..
The English images of 80 Gbs as well, but the larger images (160,250 Gbd) include even more learning contents
Additional learning content
Additional learning content can be added after the installation process if you are not using the autodeploy.sh method that allows you to add additional content during installation. We will come back to this later...
External USB hard disk preparation (1+ TB)
The downloaded images are already unpacked and ready to use. Copy them to an external hard drive or a local server. The USB disk must be formatted to store large files. For example, FAT32 is not possible because FAT32 can only handle files smaller than 4GB. NTFS is the recommended filesystem for an external hard disk.
The automated installation scripts require to be saved to an external hard disk without a parent directory, as they are stored on the FTP server. For further details please refer to the manual http://ftp.labdoo.org/download/install-disk/labdoo%20autodeploy%20and%20...
