How To Create Multiple Bootable Operating Systems on One USB Stick/Pendrive

Creating a bootable USB disk comes handy when we have to reinstall our operating system in the case of a system failure. It’s very easy to put ISO files on portable flash drives by using various tools–like Windows USB/DVD tool and the Startup Disk Creator in Ubuntu.

Now, there are many OS available in the market, either free or paid. Each having its multiple versions and features. You can’t waste a flash drive for each of them. It would be great if you put all the ISO files on one flash drive and take the advantage of installing multiple operating systems through a multiboot USB media.

The process to create a multiboot USB disk is quite simple. For Windows OS, these multiboot USB disks can be created using a popular tool known as WinSetupFromUSB. It allows you put multiple ISOs in one installation disk. You can put Windows and Linux in a same bootable disk or create a master installation disk of Windows 7, Windows 8.1, and Windows 10. The choice is up to you.

How to install an ISO file of any operating system on a USB stick

  • Download WinSetupFromUSB and extract the software on your PC/laptop.
  • Connect your USB stick to your PC/laptop.
  • Open WinSetupFromUSB. Open the 32-bit and 64-bit version according to your OS.
  • Select your USB stick from the drop down menu. If the software doesn’t recognise your pen drive, press refresh.

Now let us get down to the business of installing multiple ISO files of different operating systems on a single USB pen drive.

  • Now come back to the main screen of the App and select the checkbox of the OS you want to install on your USB stick. Note: If the size of your ISO is larger than 4 Gb, it will show a message to split the file into parts. This is because you’ve chosen the FAT32 option. Click OK.
  • Press GO. That’s it. The software will now format your pen drive and install the ISO that you have selected.

How to install second bootable ISO file of any operating system on that same USB pen drive
