Inicio Rápido USB OsGeo Live

OSGeo-Live se puede instalar en una memoria USB. Arrancará más rápido que desde el DVD.


 * Requisitos
 * Memoria USB de 8GB USB para osgeo-live (con instaladores Windows y Mac)
 * Memoria USB de 4GB USB para osgeo-live-mini (sin instaladores Windows y Mac)
 * Un ordenador moderno que permita iniciarse desde USB. (si no, hay alternativas, ver http://pendrivelinux.com)
 * Una ISO de osgeo-live de http://live.osgeo.org/en/download.html

Applications &rarr; System &rarr; Startup Disk Creator usb-creator-gtk -i osgeo-live-mini-5.0.iso
 * Run an OSGeo-Live DVD
 * Descargar la mini ISO al disco duro.
 * Insertar el USB
 * Arrancar la herramienta Startup Disk Creator:
 * XFCE (e.g. OSGeo Live)
 * Navegar para seleccionar la mini ISO en el disco duro.
 * Alternate method to launch from command line and already select the target iso
 * Entonces elegir la unidad USB de la lista, seleccionar "Documents stored in extra space", establecer el tamaño slider a su maximo y cliquear en "Make startup disk". Esta herramienta necesita This tool wants your USB drive to start with an empty FAT32 partition.


 * Reiniciar el PC y establecer en la BIOS o el Menú de Arranque (Boot Menu) para arrancar desde el dispositivo, salvar los cambios y reiniciar de nuevo.

Setting the USB drive disk label

 * 

Se da por hecho que hay ya una partición vacía de 4Gb vfat (0C) en el dispositivo USB. En caso contrario, la herramienta System Disk Creator hará esto si se presiona en el botón "Erase Disk".
 * nota: if doing it manually, the target vFAT partition must have the bootable flag set.

Abrir un terminal, teclear "mount" para mostrar las particiones montadas. El dispositivo USB estará montado en un lugar como /dev/sdf1. Apuntarlo.

unmount el dispositivo USB con: umount /media/1E1D-F5ED (poniendo en vez de "1E1D-F5ED" el nombre que corresponda del dispositivo)

Entonces abrir la herramienta Gparted del menú Applications &rarr; Settings. From the pull down list of drives in the top right select the one noted above as the USB drive. In the main bar you should see 4000 MB total for a 4gb USB drive. Right click on the partition line and select the option for Label. Change it to "OSGeoLive60" (max 11 chars). Then click the check(tick) mark icon on the top toolbar.

Instalación persistente con un USB de 4 gb
La herramienta USB System Disk Creator que viene con Ubuntu 12.04 tiene un tamaño mínimo de disco persistente de 1024 megabytes. Since the OSGeo Live iso (mini) takes 3.2gb of the available 3.7gb vFAT partition on a 4gb USB drive, we only have 545 megabytes free and the "Select persistence size" slider remains greyed out. We will have to edit the hardcoded limit down to 256 mb. Note that the persistent space records any change to the base iso, and so fills up rather quickly (about 170mb will be used almost immediately). By only giving it half the recommended free space (545 instead of 1024 mb) you'll need to be judicious in your changes to the base system. For example, installing software updates may eat all the space you have. Note that due to the limitations of the vFAT partition format you are also limited to a maximum persistent size of 4GB. On a 8gb USB drive this will mean that there will be a few hundred MB free on the drive, you can use Applications &rarr; System &rarr; Gparted to create a new EXT3 or EXT4 partition in the free space to make it usable.

The fix:
 * edit /usr/lib/python2.7/dist-packages/usbcreator/misc.py and on line 22 change MIN_PERSISTENCE = 1024 to 256. You will have to be the super user to do this, so sudo is needed:

sudo nano /usr/lib/python2.7/dist-packages/usbcreator/misc.py

After that, you can install OSGeo Live 6.0 on a 4GB USB drive, with persistence. In the System Starup Disk tool make sure "Stored in reserved extra space" is selected and slide the slider as far as it will go to the right.

 * 1) Iniciar desde un OSGeo-Live o Ubuntu/Xubuntu DVD, y entonces crear un USB usando el método de Ubuntu.

 * Nota: this method does not create a persistence space, so the live usb will 'forget' changes or settings you made.

Hint: Make sure the computer you want to boot the USB stick on has booting from the USB device enables. If not go into the BIOS change the boot settings, save your changes and reboot.
 * 1) Download an OSGeo-Live ISO
 * 2) Run the Rufus formatter and bootable USB drive creator
 * 3) Select device and enable 'Create a bootable disk using:' and select the iso image downloaded above with the button on the right, click Start

Note: We have previously had success building with the PenDriveLinux USB Installer, however as of OSGeo-Live 5.5, we have been unable to get it working.

= Build OSGeo-Live USB from other Linux =

Ubuntu

 * Use the same instructions as building from Live DVD or Live USB, adjustements noted below. Ubuntu version must be the same or newer than the one OSGeo-Live is built with.
 * For OSGeo Live 6.0 you need Ubuntu 12.04 or newer
 * For OSGeo Live 5.0/5.5 you need Ubuntu 11.04 or newer
 * For OSGeo Live 4.0/4.5 you need Ubuntu 10.04 or newer

Fedora
= Alternate method for Mac,Linux or Windows =
 * Download an OSGeo-Live ISO
 * Install and run one of the following tools (this method does not create a persistence space, so you can't save changes to the Live usb)
 * Unetbootin http://unetbootin.sourceforge.net/
 * Multisystem http://www.pendrivelinux.com/multiboot-create-a-multiboot-usb-from-linux/

= Establecer el orden de arranque en la BIOS:=
 * La mayoría de lor ordenadores no tienen establecido el arranque desde el USB por defecto.
 * Para cambiar esto, iniciar el ordenador y pulsar la tecla apropiada al inicio para acceder a la BIOS (normalmente presionando la tecla de  o alguna  o algo similar).
 * Seleccionar para arrancar desde el dispositivo USB.
 * Hay que notar, que en algunos equipos, será necesario tener algún USB conectado para poder seleccionarlo.
 * También ocurre a menudo que los USB aparecen listados más como discos duros que como dispositivos extraibles.

=Run=
 * Reiniciar el ordenador con el nuevo orden de arranque ya establecido en la BIOS.
 * Se arrancará en un sistema Xubuntu, con aplicaciones Geospaciales instaladas.
 * Si aparece una página de login al inicio, simplemente presionar Return o esperar or wait for the countdown to timeout.
 * Probar las múltiples aplicaciones del menú "GeoSpatial".

Known issues:
 * Mac computers will not boot from this USB, please use the LiveDVD
