make clean

To build ISO with kernel.elf, create dir, in this dir create "boot" dir, in "boot" dir create "grub" dir. (Move kernel.elf in "boot" dir) In "grub" dir create "grub.cfg" file and write this text to "grub.cfg":

set timeout=5
menuentry "Kernel" {
  multiboot2 /boot/kernel.elf
  boot
}

Also to build ISO you need this packages: mtools, xorriso, grub-pc-bin. To build iso: grub-mkrescue -o kernel.iso make ("make" is your dir)
