The only thing is that once you have created your Mint 18 USB drive with dd or with mintstick, you have a ISO9660 filesystem, which can prevent you from using the flash drive for other things. I know from experience that sometimes you need to clean up the first 64 sectors of the disk. You can't delete it by deleting partitions. You can delete all of your partitions, and it will still be there.
You can fix that with the dd command.
You can erase the boot area (including the partition table) by zeroing out the first 1MB of the drive, so that you have a fresh start.
Code: Select all
sudo dd if=/dev/zero of=/dev/sdb bs=1M count=10
Open GParted and locate the USB drive using the drop-down menu at the top right.
Unmount the USB drive - right click > Unmount
Create a new partition table: Device menu > Create Partition Table > msdos > APPLY
Now you have a clean USB drive ready for MultiSystem to use.
