I have Sandisk 16 GB and 32 GB Pendrives. I use Win32DiskImager and UniversalUSBInstaller and lili etc for each one 16 and 32 GB pen drives. For 16 GB is working successfully but 32 GB it says unable to find a medium containing a live file system. And this is not happening with me but also to my friends having 32 GB USB. Why is this happening and what is the solution?
Have you tried this method? You also may need to format the usb drive as bootable first, use
format fs=fat32
