usb download

edit

I will assume you would like to install a linux live distro (fedora 16 maybe?) on a usb stick device.

There are several ways o do so but these are my favorites.

Graphical:

Download and install the unetbootin package. A fast way is to run the following from a command line:

sudo yum install unetbootin -y

Then launch the software and select the distro iso image file and burn it in to the usb device.

Command line:

Note: the following method is more advanced and might be dangerous if you select the wrong target device (/dev/sdX)

My favorite way to quickly setup a live usb fedora 16 distribution is via the dd command:

sudo dd if=/path/to/Fedora-16-x86_64-Live-Desktop.iso of=/dev/sdX bs=1024

it may take a while to complete depending on your usb speed and the iso file size. Before running this command you have to identify your target usb device (/dev/sdX). An easy way to find out the correct device name is to run the dmesg command right after you plugged in the usb stick. As an example attaching my 8GB usb I can see the following output from dmesg command:

dmesg

The target device is sdb (then I should use /dev/sdb)

For me the easiest way is to use liveusb-creator:

# yum install liveusb-creator

(has option for persistent storage).
