I've been trying to convert a bootable live OS 'multiboot' USB to ISO for burning to DVD.
The USB boots fine and was made using multibootUSB - which has a bootloader with options to load various different Live OS - all work fine
Have tried to create an IMG file (which mounts fine with Ubuntu Disk Image mounter) but converting to an ISO:
mkisofs -o <iso output file name> <mountpoint>
results in an ISO that reports
boot failed could not read from cdrom boot failed could not read the boot disk no bootable device
all this tested using QEMU and also Virtualbox
Anyone know how to create a bootable ISO file that will work...? Thanks
