SoaS installation on USB/SD devices

with Microsoft Windows

Windows.gif There are three ways to do this:

  • 1. Burn a CD-ROM disc, boot from it, then run the script, livecd-iso-to-disk
    1. Use Windows 7 built-in Disk Image Burner or a free utility, like ImgBurn, to write the downloaded Sugar on a Stick .iso file onto a blank CD.
    2. Insert a USB flash drive (or SD Card Notes) with 2 GB or more of free space into your computer.
    3. Boot your computer with the CD-ROM disc. You probably need to press F1, F10, F12, Esc, or a similar key as the computer starts up in order to set the boot source for your computer to the CD-ROM device.
    4. A successful boot will take you into Sugar on a Stick. You can From there, open the Terminal Activity, Activity-terminal.png, from the Home list View.
    5. Switch to run commands with 'root' user permissions by entering su - on the command line.
    6. Change the working directory, by entering cd /run/initramfs/live/LiveOS
    7. Verify the USB/SD scsi drive node name (such as sda, sdb, etc.) and partition (such as 1, 2, etc.) for your USB/SD device. It would look like, for example, /dev/sdb1.
      • The df -Th command shows your device filesystem on a device node, for example, /dev/sdb1, mounted on a directory mount point, such as /run/media/liveuser/<USBdeviceManufacturer>
          You should see something like the following: 
          [root@localhost ~]# df -Th
Filesystem          Type      Size  Used Avail Use% Mounted on
/dev/mapper/live-rw ext4      2.9G  2.1G  773M  74% /

vartmp              tmpfs     2.0G     0  2.0G   0% /var/tmp
/dev/sdb1           vfat      3.8G  4.0K  3.8G   1% /run/media/liveuser/SanDisk
  1. Unmount the USB device filesystem with this command: umount /run/media/liveuser/MyUSBdiscMountPoint, where MyUSBdiscMountPoint is SanDisk in the dropdown example, above.
  2. Execute this command line:  (Substitute the /dev/sd?1, below, with the node name you determined in step 7, above.)
    ./livecd-iso-to-disk --reset-mbr --overlay-size-mb 500 --home-size-mb 800 --delete-home --unencrypted-home /run/initramfs/livedev /dev/sd?1
    3. (The 500 and 800 size values, above, are suitable for a 2 GB USB device. For a 4 GB device, one might use 1000 and 1600 megabytes instead.)
    The installation transcript should look like the following: 
    [root@localhost LiveOS]# livecd-iso-to-disk --overlay-size-mb 500 --home-size-mb 800 --unencrypted-home /run/initramfs/livedev /dev/sdb1

Target device is now set up with a Live image!
  3. Shutdown the physical machine.
  4. Reboot your computer from the newly-installed Live USB with Sugar on a Stick.


  • 2. Use Fedora Live USB Creator
    (This installation method is NOT recommended for LONG-TERM usage of Sugar on a Stick!! Catastrophic data corruption may occur when the USB stick gets full! See why.)
    1. Download the Live USB Creator from Fedora.
    2. Insert a USB flash drive (or SD Card Notes) with 2 GB or more of free space into your computer.
    3. Launch Live USB Creator.
    4. Select Either
    5. 1) the 'Browse' button to 'Use existing Live CD' and find the downloaded .iso file image on your system.
    6. 2) Download Fedora and select Fedora-SoaS-{i386|x86_64}-{22|23} (This automates the download and checksum routine and directly burns to the USB/ SDCard
    7. Adjust the Persistent Storage slider. This enables you to save changes to the system and additional Sugar Activities onto the device. (aka persistence file or Overlay --this space by default is write once only) --see below for additional way to make /home a rw overlay
    8. Select your flash drive as the target, and click the Create Live USB button.
    9. With the latest version of Fedora LiveUSB Creator you have TWO (2) option for burning method
    10. 1) CP (non destructive) -- meaning you can still use the unused space on a larger (8-16-32-64Gb) usb for whatever post burn.
    11. 2) DD ( the old school way) Note: THIS WILL destroy any previous data make sure you properly select the drive to use AND make backups of any pre-existing important data (you will not be easily able to retrieve overwritten data)
    12. Wait for the process to finish, then close the Live USB Creator program.
    13. Stop your flash drive with the Safely Remove Hardware and Eject Media notification area icon dialog, and eject it.
See a screenshot tutorial for this.
See a video of an earlier version of this process.


  • 3. Launch a virtual machine with the Sugar on a Stick .iso file, then run the script, livecd-iso-to-disk
    1. Download and install VirtualBox (for example; you could do something similar with another vm).
    2. Create a new virtual machine.
    3. Choose Linux for the Operating System and Version Fedora (64 bit) if available, or Fedora, on systems lacking 64-bit functionality.
    4. Attach the Sugar on a Stick .iso file as a CD in the Storage Section
    5. Insert a USB storage device into your physical computer and enable the VirtualBox USB controller. Then add a filter to recognize the inserted device in the USB section of the VirtualBox machine setup.
    6. Start the new virtual machine.
    7. Verify that the USB device is recognized in the running virtual machine.
      • Your device appears in the hover box for the USB stick icon in the virtual machine bottom frame.
      • df -Th shows your device filesystem on a device node, for example, /dev/sda1, mounted on a directory mount point, such as /run/media/<AccountName>/<USBdeviceManufacturer>
        You should see something like the following: 
        [root@localhost LiveOS]# df -Th
Filesystem          Type      Size  Used Avail Use% Mounted on

/dev/sda1           vfat      3.7G  2.1G  1.7G  56% /run/media/liveuser/TOSHIBA
  1. Continue from step #4 in the Burn a CD-ROM disc section above.
  2. Shutdown the virtual machine.
  3. Reboot your physical computer from the newly-installed Live USB with Sugar on a Stick.

Notes

A Secure Digital (SD) card may not be marked as a bootable device. To check this, use these instructions at a Linux terminal or console:

  • Check the disk partition table for a device, such as /dev/sdc,
sudo fdisk -l /dev/sdc   <----that's a lowercase letter 'L' for the list option.
    You should see something like the following: 
    $ sudo fdisk -l /dev/sdc

Disk /dev/sdc: 4012 MB, 4012900352 bytes
124 heads, 62 sectors/track, 1019 cylinders, total 7837696 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0000a9c7

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1   *          62     7834071     3917005    c  W95 FAT32 (LBA)

    The asterisk, * , under the Boot column indicates that the partition is bootable.

        If it is missing, then execute the commands here:
    1. parted /dev/sdc
    2. toggle 1 boot
    3. quit

with GNU/Linux

Gnulinux.png (See Sugar on a Stick/Linux for more details.)

  1. Use this script file http://bit.ly/livecd-iso-to-disk to create a bootable image.
    (Run chmod +x livecd-iso-to-disk.sh after you download the script to make it executable.)
  2. Execute, as the root user, in one command with arguments, the following:
    ./livecd-iso-to-disk.sh --reset-mbr --overlay-size-mb 300 --home-size-mb 175 --delete-home --unencrypted-home /path/to/source.iso /dev/sd?1
    where '?' in the final parameter represents the target bootable device node, such as sdb1 or sdc1, etc.
    Be certain of your USB/SD scsi drive node name (such as sda, sdb, etc.) and partition (such as 1, 2, etc.).
    Use the df -Th command to confirm your devices before executing the script.
         You should see something like the following: 
[root@MyComputer ~]# df -Th
Filesystem    Type    Size  Used Avail Use% Mounted on
/dev/sda1     ext4     18G  6.6G   11G  38% /

/dev/sdb1     vfat     15G  2.0G   13G  14% /media/TOSHIBA
where the mount point and filesystem sizes should help you identify what you want.
$ sudo ./livecd-iso-to-disk.sh --reset-mbr --overlay-size-mb 300 --home-size-mb 200 --delete-home --unencrypted-home /mnt/VMs/Fedora-13-x86_64-Live-SoaS.iso /dev/sdb1
