Grub4Dos boot-USB

1. Check disks and partitions

sudo blkid

2. Unmount USB’s active partition.

sudo umount /dev/sdXY ## where X=disk and Y=partition

3. Open Terminal and go to the folder where the image is or open Terminal in that folder.

4. Copy image to the USB

sudo cp grub4dosBOOT.img /dev/sdX ## where X=disk

Warning! If you are not sure what you are doing, do NOT do!

Edit: Safer way to put the image to an USB is to use Etcher.
