After writing the ISO on the usb drive(16GB memory) with win32DiskImager, Gparted shows three partitions on the drive: the first of 2.8GB (where I assume the ISO has been written), a second partition of 105MB labeled as FAT, and a third one of about 12GB of free unallocated space....My doubt: Is normal to have the FAT partition???....I've done this process several times on this drive with these same tools in the past, but I don't remember I've ever had a FAT partition after the ISO writing process....anything's wrong?
