Now, if you are looking for a way to clone a bootable USB drive to another, here is how you can clone (make identical copies of) bootable USB drive easily. It may be very useful, especially if it is a multi-bootable USB drive. Here is how it is.
- First download a small utility called ImageUSB. It is free and portable application and can preserve all unused and slack space during the cloning process, including the Master Boot Record (MBR). 
- Connect the bootable USB drive to your PC that you want to clone. 
- Extract the ImageUSB zip file and run the exe file. Select the USB drive and then click on “Create from UFD” option. 
- Now, browse the directory where you want to save the image of bootable USB drive. It will save as .bin file on your computer. 
- Now, click on “Create image” button to begin process. It’ll take some times to complete the process. Now, you have the full image of your bootable USB drive on your PC. 
- Next step is burning the image to another USB drive. 
- Insert your new USB pen drive and click on “Refresh Drives”. Select your pen drive from the list and click “Write to UFD” option. 
- Now, browse the image file (bin file) which you had just created and click on “Write to UFD” button. That’s all. Note: Using the image back up you can make as many bootable clone pen drives as you wish. ImageUSB can be downloaded (450KB) from developer’s website here.
