[IMPORTANT]
By default a compatible master boot record (MBR) is installed on the device
-(being for example /dev/sdb when executing 'grml2usb grml.iso /dev/sdb1')
+(being for example /dev/sdx when executing 'grml2usb grml.iso /dev/sdx1')
and grub is being used as default bootloader. Avoid installation of the
default MBR using the --skip-mbr option or if you encounter any problems
with the default MBR consider using --syslinux-mbr instead. If bootloader
