Creating The Live Medium
A Live medium is a data storage device like a CD, DVD or USB stick that allows you to try out and install gNewSense. This section explains how to create a live medium from a gNewSense ISO image. If you haven't already done so, please download an ISO image from the downloads page.
To create a Live CD/DVD you need a burning software that allows you to write ISO images. Most burning software already have this feature. If you are using Microsoft Windows, you can use a program like InfraRecorder, which is free software. If you are using a GNU/Linux distribution you can use Brasero, K3B or Xfburn.
The steps to write an ISO image to a CD/DVD are pretty much the same for any burning software:
- Insert a blank CD/DVD.
Open your burning software and choose Write image.
Select the gnewsense-live-Y.Z-arch-desktop.iso file you chose from the Downloads page.
Change Write speed to the lowest value.
- Start writing to the CD/DVD.
This process will take several minutes. When it finishes, you should have a functional Live CD/DVD and just need to go ahead and try it.
Backup all the data present in the USB stick
Before you start, be sure to backup all the data present in the USB stick, if any, as the procedure to write the ISO to the stick will destroy/over-write the existing content.
Do not use UNetbootin or LinuxLive USB Creator to create the Live USB
Live USBs created with UNetbootin or LinuxLive USB Creator are not working correctly. Please follow the instructions given in this page instead. This bug has been reported to gNewSense as bug #39912 and bug #39986.
For Microsoft Windows Users
If on Windows, use the (GNU) LinuxLive USB Creator to create the Live USB stick. Follow the instructions in the website. Once you have created your Live USB stick, go ahead and try it. Windows USB instructions are still being finalized in light of recent bugs.
For GNU/Linux Users
If on GNU/Linux. Insert the USB stick.
Find the USB stick's device file name by doing:
$ dmesg | tail ... [ 488.727644] sd 8:0:0:0: [sdb] Attached SCSI removable disk ...
sdb (inside the square brackets) is the device file name for the stick. The device file name can be different (such as sdf), therefore, let's generically call it sdX from now on.
You should replace sdX with the device file name of the USB stick in your machine.
If the stick is not already mounted, mount it by doing:
$ udisks --mount /dev/sdX1
It will be mounted at /media/usb-stick-name.
Now unmount the USB stick.
$ udisks --unmount /dev/sdX1
Write the ISO image to the USB stick by doing:
$ cat /path/to/iso/gnewsense-live-Y.Z-arch-desktop.iso > /dev/sdX
That will set the USB stick to boot the Live session. Now, go ahead and try it.
