I am searching for a linux tool to create a multiboot dvd.

I found something about Sardu or Xboot, but these are Windows tools. Is there Linux software that can do the same? I have found unetbootin and yumi but both create multi boot usb drives, instead of multi boot dvd's.

Or can I make a bootable usb and then copy the contents (to an iso file and burn this file) to dvd?

  • K3b is a useful tool for writing isos. isolinux can be used to assemble the ISO. – jpe Oct 10 '14 at 15:30

The descriptions for creating a bootable USB stick usually lead to an MBR and a FAT fileystem. Both will not suffice to boot from CD/DVD via x86 BIOS. An EL Torito enhanced ISO 9660 filesystem is needed.

But the files in the FAT filesystem probably constitute a runnable operating system. So you can use them as payload for an ISO which contains bootloader equipment of ISOLINUX or GRUB2. If more than one operating system shall be bootable, then you will have to learn how to augment the menu configuration files of the bootloaders.

The bootloader suite GRUB2 has a program called grub-mkrescue which produces ISO filesystem images bootable by BIOS and EFI:

grub-mkrescue -o grub.iso ...your.operating.system.payload.files...

See https://www.gnu.org/software/grub/manual/html_node/Invoking-grub_002dmkrescue.html

The bootloader suite SYSLINUX has a module ISOLINUX, which provides the equipment for booting via BIOS. The production of the ISO filesystem image is then done by programs mkisofs, genisoimage, or xorrisofs.

See http://www.syslinux.org/wiki/index.php/ISOLINUX

The resulting filesystem image can then be burned to CD, DVD, or BD by the usual burn programs. Make sure you choose to burn a pre-formatted image, rather than composing a new ISO filesystem.

Since grub-mkrescue depends on xorriso, you may use that one for burning, too:

xorriso -as cdrecord -v dev=/dev/sr0 -eject grub.iso

  • thanks. I have chosen the easy way for now: borrowing an ps/2 keyboard which also helped me for now to boot the right distro. – DutchArjo Oct 16 '14 at 17:30
