MultiBoot USB is a useful application (USB installer) that allows users to install multiple live Linux distros (Ubuntu, Fedora, LinuxMint, etc.) from a bootable USB flash drive (pendrive). You can then test your USB drive using QEMU without the need to restart.
The use of MultiBoot USB is very simple, it comes with a clear and easy user interface that allows to add/delete installed distro at any time. To install MultiBoot USB on Ubuntu 11.10/11.04, open the terminal and run the following commands:
wget -O MultiBootUSB_4.7.tar.gz http://goo.gl/6ojXA
tar -xzvf MultiBootUSB_4.7.tar.gz -C ~/
The software will be installed in the home directory. To start it, double-click MultiBootUSB.sh and click Run, or launch it with this command:
cd ~/MultiBootUSB && ./MultiBootUSB.sh
The software requires root privileges, submit your user password and click OK:
Select your USB drive from the given list and click OK:
Select now whether to add distros manually or use auto mode:
Select now the distribution(s) iso from your hard drive or any other storage media and click OK:
You will be prompted if you want to add more Linux distros. For this example we will see only how to add one distro, so we will click No:
Select now the distribution(s) you want to install from the list and click OK:
Do not disconnect your USB flash drive and wait while your ditribution(s) is being installed. When the installation is complete, you will get a notification message, sometimes not. If you want to test your USB drive using QEMU, you can install it under Ubuntu with this command:
sudo apt-get install qemulator
Then use it to boot from your USB flash drive.
