Format USB stick
sudo fdisk -l #find out your usb device df umount /dev/sdb1 mkfs.vfat /dev/sdb1 #create fat32 mkfs.ext3 /dev/sdb1 #create ext3 mkdosfs -F 32 -I /dev/sdb1 #format device to fat32
Copy .iso on USB stick
sudo dd if=image.iso of=/dev/sdb1
Mount .iso
sudo mkdir /mnt/isoimage sudo mount -o loop -t iso9660 image.iso /mnt/isoimage/
