Boot up a Linux Operation System from a USB Flash Drive

Linux Live Operation System become handy when your Windows OS crashed, you can boot up your computer with the USB Linux OS Flash Drive, and backup all your important data; or use it to install to a Laptop, a Netbook that has no CD-ROM Drive.

Fedora 12 - a Linux Live OS is automatic hardware detection, and support for many graphics cards, sound cards, SCSI and USB devices and other peripherals.
It is not necessary to install anything on a hard disk. 

Fedora (Download here) makes it very easy to create a bootable USB stick with the Live USB Creator tool.

You can also tell the tool how much persistent storage to reserve on the USB stick. This space can be used to save files and make modifications to the LiveCD image, allowing you to boot and run Fedora with any changes you make.


Insert the USB Flash Drive to use (should be at least 4GB in size), and when you have chosen which version of Fedora on a Flash Drive to install, or have supplied your own LiveCD image, click the Create Live USB button. Make sure that the target device shows up properly; if it isn’t already selected, make sure you select the correct device (i.e., /dev/sdg1 on Linux or ‘E:’ in Windows). Note that the install is completely non-destructive, so the device can contain other data as well.

When the Live USB Creator is completed, you can eject the USB Flash Drive, insert it into your other computer (or reboot the existing computer) and indicate in the BIOS or via boot selection at startup which device to boot from. Select the USB Flash Drive and watch Fedora boot, at which point you can either select to use Fedora as installed on the USB Flash Drive, or use it to install Fedora onto the computer.
