MultiBootUSB is a free software tool for Linux and Windows that creates a bootable flash drive containing multiple ISO images. Any one of which can be run on a compatible desktop or laptop computer from a simple user interface.
Insert a FAT32 formatted flash drive.
You will find the installed program under the heading of “System Tools” in your main menu.
Enter your super secret password.
Click on the “Browse ISO” button to locate and select the image you wish to add to the flash drive.
Click the “Create” button.
Persistence is additional space allocated to the ISO image. You can think of the flash drive as the operating system’s hard drive. Anything you add to the OS while running in Live mode will be written to the flash drive.
It’s a good idea to give the ISO image at least a minimum of half the amount of persistence relative to the size of that image. So if the image is 1GB in size, set the persistence size to 512MB. More would be better. It just depends on how much free space you have on the flash drive.
Click the “Choose” button.
MultiBootUSB gives you the opportunity to continue or cancel the operation.
Click “Yes” to continue.
The ISO image is now being added to the flash drive.
Click “OK” when finished.
The new ISO image is now displayed in the list of the main screen.
To remove an ISO image, click on the image you want to remove to select that image and click on the “Uninstall Distro” button. You will be given the opportunity to change your mind. Click “Yes” to continue.
If you want to install only a single ISO image, click on the “ISO Imager” tab.
The process is similar, but you will not need to set the persistence size.
That’s all there is to it. Your flash drive is now ready for booting.
