Ever felt like carrying your Ubuntu, Fedora, Tiny-core and all other OS’s iso in your pen drive? Yes, you can now carry all your favorite Operating systems with you wherever  you go and boot from them using the same USB drive.MultiBoot USB is a freeware which can help you to use the multiple OS iso files on the same pen drive.
To use the MultiBoot on your pen drive it must meet some requirements first. You’ll require a FAT32 formatted pen drive and a computer which can boot from a USB device. Prefer using an 8-16 GB pen drive so that you can have more different operating systems on it.
To start off first download the MultiBootISO’s from here . Run the executable and follow the instructions. Browse to the ISO file you want to load on your USB drive and build the bootable USB using it. You might have to format your pen drive during the process so do take a backup of all your data which is there on the pen drive.
To add more ISO files repeat the same procedure. Restart your PC and set the highest priority for the USB drive to boot from it and done. Do give it a shot!!! :)
