setting up boot DVD

  • 772

I am interested in setting up a boot DVD, a DVD from which I can boot, containing a kernel which is compatible with Ubuntu.

Is this a reasonable thing to attempt? Is there a command I can use which will generate such a DVD?

boot

    It is "trivial" to do this.

    1) Install the necessary packages 

    sudo apt-get install syslinux genisoimage

    2) Make a working directory

    mkdir -p DVD/isolinux

    3) Move your kernel, initramfs, and isolinux.bin to the working directory

    cp /boot/vmlinuz-your-kernel DVD/isolinux
cp /boot/initramfs-your-initramfs.img DVD/isolinux
cp /usr/lib/syslinux/isolinux.bin DVD/isolinux/

    4) Create (write) a isolinux.cfg file, save it at DVD/isolinux/isolinux.cfg

    DEFAULT live
LABEL live
menu label ^Ubuntu kernel , boot hard drive
kernel /isolinux/vmlinuz-your-kernel
INITRD /isolinux/initramfs-your-initramfs.img
append  root=/dev/your_root_partition ro quiet splash --
TIMEOUT 300

    5) Make the iso

    cd DVD
sudo mkisofs -r -V "Live-DVD" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o ../ubuntu-dvd.iso .
cd ..

    6) Burn the DVD, although it will fit on a flash drive or CD easily.

    For additional information see

    https://wiki.archlinux.org/index.php/Syslinux

    The arch wiki page has great information on syslinux, and some splash and menu options I did not cover.
