Live OS CD to USB Script
Prerequisites:
1. Insert your LiveOS CD/DVD and USB drive.
2. CR drive is automatically selected and USB drive you need to choose when prompted.
3. By default, script takes whole device, in case of partition, you need to create and mention it.
4. Size of USB drive should be same or more than that of CD/DVD drive/image size.

Live OS CD to USB Writer Tool or Script enables you to write your Live Linux Operating System CD to a USB drive.
I. Download Script
[root@nglinux ]# mkdir /usr/nglinux; cd $_; \ wget --auth-no-challenge http://ngelinux.com/scripts/ngelinux_usb_install.sh; \ wget --auth-no-challenge http://ngelinux.com/scripts/livecd-iso-to-disk; \ chmod +x ./livecd-iso-to-disk ./ngelinux_usb_install.sh;
